                RESEARCH REPORTING SERIES

Research reports of the Office of Research and Development, U.S. Environmental
Protection Agency, have been grouped into nine series. These nine broad cate-
gories were established to facilitate further development and application of en-
vironmental technology.  Elimination  of traditional grouping was consciously
planned to foster technology transfer and a maximum interface in related fields.
The nine series are:

      1.  Environmental  Health Effects Research
      2.  Environmental  Protection Technology
      3.  Ecological Research
      4.  Environmental  Monitoring
      5.  Socioeconomic Environmental Studies
      6.  Scientific and Technical Assessment Reports (STAR)
      7  Jnteragency Energy-Environment Research and Development
      8.  "Special" Reports
      9.  Miscellaneous Reports

This report has been assigned to the ECOLOGICAL RESEARCH series. This series
describes research on the effects of pollution on humans, plant and animal spe-
cies, and materials. Problems are assessed  for their long- and short-term influ-
ences. Investigations include formation, transport, and pathway studies to deter-
mine the fate of pollutants and their effects. This work provides the technical basis
for setting standards to minimize undesirable changes in living organisms in the
aquatic, terrestrial, and atmospheric environments.

                                FOREWORD

     Our nation's fresh waters are vital for all animals and plants,  yet our
diverse uses of water — for recreation, food,  energy,  transportation, and
industry — physically and chemically alter lakes,  rivers,  and streams.  Such
alterations threaten terrestrial organisms, as  well as  those living in water.
The Environmental Research Laboratory in Duluth, Minnesota,  develops  methods,
conducts laboratory and field studies, and extrapolates research findings

     —to determine how physical and chemical pollution affects
       aquatic life;

     —to assess the effects of ecosystems on pollutants;

     —to predict effects of pollutants on large lakes  through
       use of models; and

     —to measure bioaccumulation of pollutants in aquatic
       organisms that are consumed by other animals, including
       man.

     This report discusses the history, procedures, and derivation of
temperature criteria to protect freshwater fishes and presents numerical
criteria for 34 species.  It follows the general philosophical approach
of the National Academy of Sciences and National Academy of  Engineering in
their Water Quality Criteria 1972 and is intended to make that philosophy
practically useful.

                                   ABSTRACT

     Temperature criteria  for  freshwater  fish are  expressed as mean and
maximum temperatures;  means  control functions such as  embryogenesis,  growth,
maturation,  and reproductivity,  and maxima  provide protection for all life
stages-against lethal  conditions.   These  criteria  for  34  fish species are
based on numerous field and  laboratory  studies,  and yet for some important
species the  data are still insufficient to  develop all the  necessary
criteria.  Fishery managers, power-plant  designers,  and regulatory agencies
will find these criteria useful  in  their  efforts to protect fishery resources.

                           SUMMARY AND CONCLUSIONS

     The evolution of freshwater temperature criteria has advanced from the
search for a single "magic number" to the generally accepted protocol for
determining mean and maximum numerical criteria based on the protection of
appropriate desirable or important fish species,  or both.   The philosophy and
protocol of the National Academy of Sciences and National Academy of
Engineering (1973) were used to determine criteria for survival,  spawning,
embryo development, growth, and gamete maturation for species of  freshwater
fish, both warmwater and coldwater species.

     The influence that management objectives and selection of species have
on the application of temperature criteria, is extremely important, especially
if an inappropriate, but very temperature-sensitive,  species is included.  In
such a case, unnecessarily restrictive criteria will be derived.   Conversely,
if the most sensitive important species is not considered,  the resultant
criteria will not be protective.

                                 INTRODUCTION

     This report is intended to be a guide for derivation of temperature
criteria for freshwater fish based on the philosophy and protocol presented
by the National Academy of Sciences and National Academy of Engineering (1973),
It is not an attempt to gather and summarize the literature on thermal effects.

     Methods for determination of temperature criteria have evolved and
developed rapidly during the past 20 years, making possible a vast increase
in basic data on the relationship of temperature to various life stages.

     One of the earliest published temperature criteria for freshwater life
was prepared by the Aquatic Life Advisory Committee of the Ohio River Valley
Water Sanitation Commission (ORSANCO) in 1956.  These criteria were based on
conditions necessary to maintain a well-rounded fish population and to sustain
production of a harvestable crop in the Ohio River watershed.  The committee
recommended that the temperature of the receiving water:

          1)  Should not be raised above 34° C (93°F) at any place
              or at any time;

          2)  should not be raised above 23° C (73° F) at any place
              or at any time during the months of December through
              April; and

          3)  should not be raised in streams suitable for trout
              propagation.

McKee and Wolf (1963)  in their discus'sion of temperature criteria for the
propagation of fish and other  aquatic and marine life refer only to the
progress report of ORSANCO's Aquatic Life Advisory Committee (1956).

     In 1967 the Aquatic Life  Advisory Committee of ORSANCO evaluated and
further modified their recommendations for temperature in the Ohio River
watershed.   At this time the committee expanded their recommendation of a
93° F (33.9° C) instantaneous  temperature at any time or any place to include
a daily mean of 90° F  (32.2° C).  This, we believe, was one of the first
efforts to  recognize the importance of both mean and maximum temperatures
to describe temperature requirements of fishes.  The 1967 recommedations also
included:

          1)  Maximum temperature during December, January, and February
              should be 55° F  (12.8° C);

-------
          2)  during  the  transition months of March, April, October  and
              November  the  temperature  can be changed  gradually  by not
              more  than 7°  F  (3.9° C);

          3)  to maintain trout habitats, stream  temperatures  should  not
              exceed  55°  F  (12.8° C) during  the months of October through
              May,  or exceed  68° F (20.0° C) during the months of June
              through September; and

          4)  insofar as  possible the temperature should not be  raised
              in streams  used  for natural propagation  of trout.

     The National Technical Advisory Committee of the  Federal Water Pollution
Control Administration  presented a report on water quality criteria in 1968
that was to become  known  as the "Green  Book."  This large committee included
many of the members of  ORSANCO's Aquatic Life Advisory Committee.  The committee
members recognized  that aquatic organisms might be able to endure a high
temperature for a few hours that could  not be endured  for a period of days.
They also acknowledged  that no single temperature requirement  could be applied
to the United States  as a whole, or even to  one state, and that  the requirements
must be closely related to  each body of water and its  fish populations.  Other
important conditions  for  temperature requirements were that (1)  a seasonal cycle
must be retained, (2) the changes in temperature must  be gradual, and (3) the
temperature reached must  not be so high or so low as to damage or alter the
composition of the  desired  population.  These conditions led to  an approach to
criteria development different from earlier  ones.  A temperature increment
based on the natural water  temperature  was believed to be more appropriate
than an unvarying number.   The use of an increment requires a knowledge of
the natural temperature conditions of the water in question, and the size of
the increment that  can  be tolerated by  the desirable species.

     The National Technical Advisory Committee (1968, p. 42) recommended:

          "To maintain  a well-rounded population of warmwater fishes  .... heat
          should not be added  to a stream in excess of the amount that will
          raise the temperature of the  water (at the expected minimum daily
          flow for  that month) more than 5° F."

A casual reading of this requirement resulted in the unintended  generalization
that the acceptable temperature rise in warmwater fish streams was 5° F (2.8°
C).   This generalization was incorrect!  Upon more careful reading the key
word "amount" of heat and the key phrase "minimum daily flow for that month"
clarify the erroneousness of the generalization.  In fact,  a 5°  F (2.8° C)
rise in temperature could only be acceptable under low flow conditions for a
particular month and any increase in flow would result in a reduced increment
of temperature rise since the amount of heat added could not be  increased.
For  lakes and reservoirs the temperature rise limitation was 3°  F (1.7° C)
based "on the monthly average of the maximum daily temperature."

     In trout and salmon waters the recommendations were that "inland trout
streams,  headwaters of  salmon streams,   trout and salmon lakes, and reservoirs
containing salmonids should not be warmed," that "no heated effluents should

-------
be discharged in the vicinity of  spawning areas,"  and  that "in lakes and
reservoirs,  the temperature of the hypolimnion should  not be raised more
than 3°  F (1.7° C)."  For  other locations the  recommended incremental rise
was 5° F (2.8° C)  again based on  the  minimum expected  flow for that month.

     An important  additional recommendation  is summarized in the following
table in which provisional maximum temperatures were recommended for various
fish species and their associated biota  (from  FWPCA National Technical Advisory
Committee,  1968).

            bass,  buffalo,  carpsucker,  threadfin  shad,  and gizzard
            shad.

     90 F:   Growth of largemouth  bass,  drum,  bluegill,  and crappie.

     84 F;   Growth of pike,  perch, walleye, smallmouth  bass,  and
            sauger.

     80 F:   Spawning and  egg development of catfish,  buffalo,  thread-
            fin shad, and gizzard shad.

     75 F:   Spawning and  egg development of largemouth  bass,  white,
            yellow,  and spotted bass.

     68 F:   Growth or migration routes  of  salmonids  and for egg
            development of perch  and  smallmouth bass.

     55 F:   Spawning and  egg development of salmon and  trout  (other
            than lake trout),

     48 F:   Spawning and  egg development of lake  trout,  walleye,
            northern pike,  sauger, and  Atlantic salmon.
       NOTE:   Recommended  temperatures  for  other  species,  not  listed
              above,  may be  established if  and  when  necessary
              information  becomes  available.


These recommendations represent  one   of the significant  early  efforts to base
temperature criteria  on the  realistic approach  of species  and  community
requirements  and take into account the  significant biological  factors of
spawning,  embryo development,  growth, and survival.

-------
     The Federal Water Pollution Control Administration (1969al recommended
revisions in water quality criteria for aquatic life relative to the Main
Stem of the Ohio River.  These recommendations were presented to ORSANCO's
Engineering Committee and were based on the temperature requirements of
important Ohio River fishes including largemouth bass,  smallmouth bass, white
bass, sauger, channel catfish, emerald shiner, freshwater drum, golden
redhorse, white sucker, and buffalo (species was not indicated).  Temperature
requirements for survival, activity, final preferred temperature,  reproduction,
and growth were considered.  The recommended criteria were:

          1.   "The water temperatures shall not exceed 90°  F
               (32.2° C) at any time or any place,  and  a
               maximum hourly average value of 86°  F (30° C)
               shall not be exceeded."

          2.   "The temperature shall not exceed the
               temperature values expressed on the  following
               table:"

-------
The principal limiting fish species considered in developing these criteria
was the sauger,  the most temperature sensitive of the important Ohio River
fishes.  A second set of criteria (Federal  Water  Pollution Control
Administration,  1969b)  considered less  temperature-sensitive species,  and the
criteria for mean temperatures were higher.   The  daily mean in July and
September was 84° F (28.9°  C).   In addition,  a third set  of criteria was
developed that was not  designed to protect  the smallmouth bass, emerald
shiner, golden redhorse,  or the white sucker.   The July-to-September daily
mean temperature criterion  was 86° F (30° C).

     The significance of the 1969 Ohio  River  criteria was that they were
species dependent and that  subsequently the criteria would probably be based
upon a single species or a  related group of species.   Therefore,  it is
extremely important to  select  properly  the  species that are important  otherwise
the criteria will be unnecessarily restrictive.   For example,  if  yellow perch
is an extremely  rare species in a water body  and  is  the most temperature-
sensitive species,  it probably would be unreasonable to establish temperature
criteria for this species as part of the regulatory  mechanism.

     In 1970 ORSANCO established new temperature  standards that incorporated
the recommendations for temperature criteria  of the  Federal Water Pollution
Control Administration  (1969a,  1969.b). and the  concept of  limiting the  amount
of heat that would be added (National Technical Advisory  Committee,  1968).
The following is the complete  text of that standard:

          " All  cooling water  from municipalities  or  political
            subdivisions, public or private institutions,  or
            installations,  or  corporations discharged or
            permitted to  flow  into the  Ohio River  from the point
            of confluence of the Allegheny and Monongahela Rivers
            at Pittsburgh,  Pennsylvania, designated  as Ohio River
            mile point  0.0  to  Cairo Point, Illinois,  located at
            the  confluence  of  the Ohio  and Mississippi Rivers,  and
            being 981.0 miles  downstream from Pittsburgh,  Pennsylvania,
            shall be so regulated or  controlled as to provide  for
            reduction of  heat  content to such degree  that  the  aggregate
            heat-discharge  rate from  the municipality,  subdivision,
            institution,  installation or corporation,  as  calculated  on
            the  basis of  discharge volume and temperature  differential
            (temperature  of  discharge minus upstream river temperature)
            does not exceed  the amount  calculated  by  the  following
            formula,  provided,  however,  that  in no case shall  the
            aggregate heat-discharge  rate be of such  magnitude as will
            result  in a calculated increase in river  temperature  of
            more than 5 degrees  F:

     Although the numerical criteria for January through December  are  higher
 than those recommended by the Federal Water Pollution Control Administration,
 they are only used to calculate the amount of heat  that can  be  added at  the
 "minimum daily flow once in ten years."  Additional flow would  result  in
 lower maxima since no additional heat could be added.  There was also  the ^
 increase of 5° F (2.8° C) limit that could be more  stringent than  the  maximum
 temperature limit.

     The next important step in the evolution of thought on  temperature
 criteria was Water Quality Criteria 19.72 (NAS/NAE,  1973), which is  becoming
 known as the "Blue Book," because of its comparability to the Green Book (FWPCA
 National Technical Advisory Committee, 1968).  The  Blue Book is the report  of
 the Committee on Water Quality Criteria of the National Academy of  Sciences at
 the request of and funded by the U.S. Environmental Protection  Agency  (EPA).
 The heat and temperature section, with its recommendations and  appendix  data,
 was authored by Dr. Charles Coutant of the Oak Ridge National Laboratory.   These
 materials are reproduced in full in Appendix A and Appendix  B in this  report.
 A discussion and description of the Blue Book temperature criteria  will  be
 found later in this report.

     The Federal Water Pollution Control Act Amendments of 1972 (Public
 Law 92-500) contain a section [304 (al (11] that requires that  the
 administrator of the EPA "after consultation with appropriate Federal  and
 State agencies and other interested persons, shall develop and  publish,
 within  one year after enactment of this title (and  from time to time

     The U.S.  Environmental Protection Agency (1976) has published  Quality
 Criteria for Water as a response to the Section 304(a)(l) requirements of
 PL 22-500.   That approach to-the determination of temperature criteria for
 freshwater fish is essentially the same as the approach recommended in the
 Blue Book (NAS/NAE,  1973).   The EPA criteria report on temperature  included
 numerical criteria for freshwater fish species and a nomograph  for  winter
 temperature criteria.   These detailed criteria were developed according
 to the protocol in the Blue Book,  and the procedures used to develop those
 criteria will  be discussed in detail in this report.

     The Great  Lakes  Water Quality Agreement (1972) between  the United States
of America   and Canada was signed in 1972 and contained a specific  water
quality  objective  for temperature.   It states that "There should be no change
that would  adversely  affect any local or general use of these waters."  The

-------
International Joint Commission was designated to assist in the implementation
of this agreement and to give advice and recommendations to both countries
on specific water quality objectives.   The International Joint Commission
committees assigned the responsibility of developing these objectives have
recommended temperature objectives for the Great Lakes based on the "Blue
Book" approach and are in the process of refining and completing those
objectives for consideration by the commission before submission to the two
countries for implementation.

                                   SECTION 3

                     THE PROTOCOL FOR TEMPERATURE CRITERIA

     This section is a synthesis of concepts and definitions from Fry et al.
 (1942, 1946),  Brett (1952,  1956), and the NAS/NAE (1973).

     The lethal threshold temperatures are those temperatures at which 50
 percent of a sample of individuals would survive indefinitely after acclimation
 at some other temperature.   The majority of the published literature (Appendix
 B) is calculated on the basis of 50 percent survival.   These lethal thresholds
 are commonly referred to as incipient lethal temperatures.  Since organisms
 can be lethally stressed by both rising and falling temperatures, there are
 upper incipient lethal temperatures and lower incipient lethal temperatures.
 These are determined by removing the organisms from a temperature to which
 they are acclimated and instantly placing them in a series of other temperatures
 that will typically result in a range in survival from 100 to 0 percent.
 Acclimation can require up to 4 weeks, depending upon the magnitude of the
 difference between the temperature when the fish were obtained and the desired
 acclimation temperature.  In general, experiments to determine incipient
 lethal temperatures should extend until all the organisms in any test chamber
 are dead or sufficient time has elapsed for death to have occurred.  The
 ultimate upper incipient lethal temperature is that beyond which no increase
 in lethal temperature is accomplished by further increase in acclimation
 temperature.  For most freshwater fish species in temperate latitudes the
 lower incipient lethal temperatures will usually end at Op C, being limited
 by the freezing point of water.  However, for some important species, such as
 threadfish shad in freshwater and menhaden in seawater, the lower incipient
 lethal temperature is higher than 0° C,

     As indicated earlier,  the heat and temperature section of the Blue Book
 and its associated appendix data and references have been reproduced J.n this
 report as Appendix A and Appendix B.  The following discussion will briefly
 summarize the  various types of criteria and provide some additional insight
 into the development of numerical criteria.  The Blue Book (Appendix A)
 also describes in detail the use of the criteria in relation to entrainment.

MAXD1UM WEEKLY AVERAGE TEMPERATURE

     For practical reasons  the maximum weekly average temperature (MWAT) is
 the mathematical mean of multiple, equally spaced,  daily temperatures over a
 7-day consecutive period.
                                     10

-------
For Growth

     To maintain growth of aquatic organisms at rates necessary for sustaining
actively growing and reproducing populations, the MWAT in the zone normally
inhabited by the species at the season should not exceed the optimum temperature
plus one-third of the range between the optimum temperature and the ultimate
upper incipient lethal temperature of the species:

                                        ultimate upper incipient       optimum
WAT for growth = optimum temperature +   lethal temperature	   temperature


The optimum temperature is assumed to be the optimum for growth, but other
physiological optima may be used in the absence of growth data.  The MWAT need
not apply to accepted mixing zones and must be applied with adequate under-
standing of the normal seasonal distribution of the important species.

For Reproduction

     The MWAT for reproduction must consider several factors such as gonad
growth and gamete maturation, potential blocking of spawning migrations,
spawning itself, timing and synchrony with cyclic food sources, and normal
patterns of gradual temperature changes throughout the year.  The protection
of reproductive activity must take into account months during which these
processes normally occur in specific water bodies for which criteria are
being developed.

For Winter Survival

     The MWAT for fish survival during winter will apply in any area in which
fish could congregate and would include areas such as unscreened discharge
channels.  This temperature limit should not exceed the acclimation, or plume,
temperature (minus a 3.6° F (2.0° C) safety factor) that raises the lower
lethal threshold temperature above the normal ambient water temperature for
that season.  This criterion will provide protection from fish kills caused
by rapid changes in temperature due to plant shutdown or movement of fish
from a heated plume to ambient temperature.


SHORT-TERM EXPOSURE TO EXTREME TEMPERATURE

     It is well established that fish can withstand short exposure to temperatures
higher than those acceptable for reproduction and growth without significiant
adverse effects.   These exposures should not be too lengthy or frequent or the
species could be adversely affected.  The length of time that 50 percent of a
population will survive temperature above the incipient lethal temperature can
be calculated from the following regression equation:

         log time (min)  = a + b (temperature in °C);

                             or

         temperature (°C) = (log time (min)  - a)/b.

                                      U

-------
The constants "a" and "b" are for intercept  and  slope and will be discussed
later.  Since this equation is based on 50 percent  survival,  a 3.6° F (2-0° Cl
reduction in the upper incipient  lethal temperature will provide the safety
factor to assure no deaths.

     For those interested in more detail  or  the  rationale for these general
criteria, Appendices  A and B should  be  read  thoroughly.   In addition, Appendix
A contains a fine discussion of a procedure  to evaluate  the potential thermal
impact of aquatic organisms  entrained in  cooling water or the discharge
plume, or both.

                   THE PROCEDURES FOR CALCULATING NUMERICAL

                   TEMPERATURE CRITERIA FOR FRESHWATER FISH

MAXIMUM WEEKLY AVERAGE TEMPERATURE

     The necessary minimum data for the determination of this criterion are
the physiological optimum temperature and the ultimate upper incipient lethal
temperature.  The latter temperature represents the "breaking point" between
the highest temperatures to which an animal can be acclimated and the lowest
of the extreme upper temperatures that will kill the warm-acclimated organism.
Physiological optima can be based on performance, metabolic rate, temperature
preference, growth, natural distribution, or tolerance.  However, the most
sensitive function seems to be growth rate, which appears to be an integrato-r
of all physiological responses of an organism.   In the absence of data on
optimum growth, the use of an optimum for a more specific function related to
activity and metabolism may be more desirable than not developing any growth
criterion at all.

     The MWAT's for growth were calculated for fish species for which appropriate
data were available (Table 1).  These data were obtained from the fish temperature
data in Appendix C,  These data sheets contain the majority of thermal effects
data for about 34 species of freshwater fish and the sources of the data.  Some
subjectivity is inevitable and necessary because of variability in published
data resulting from differences in age, day length, feeding regime, or methodology.
For example, the data sheet for channel catfish (Appendix C) includes four
temperature ranges for optimum growth based on three published papers.  It would
be. more appropriate to use data for growth of juveniles and adults rather than
larvae.  The middle of each range for juvenile channel catfish growth is 29° and
30° C.   In this instance 29° C is judged the best estimate of the optimum.  The
highest incipient lethal temperature (that would approximate the ultimate
incipient lethal temperature) appearing in Appendix C is 38° C,  By using the
previous formula for the MWAT for growth, we obtain

                         29° c + (38-29° Cl = ^ c_

The temperature criterion for the MWAT for growth of channel catfish would be
32° C (as appears in Table 1).

SHORT-TERM MAXIMUM DURING GROWTH SEASON

     In addition to the MWAT, maximum temperature for short exposure will
protect against potential lethal effects.   We have to assume that the incipient
lethal temperature data reflecting 50 percent survival necessary for this
calculation would be based on an acclimation temperature near the MWAT for
growth.  Therefore, using the data in Appendix B for the channel catfish, we
find four possible data choices near the MWAT of 32° C (again it is preferable
to use data on juveniles or adults):

           Acclimation temperature (° C)        ji           b_

                       30                   32.1736     -0.7811

                       34

                       30

                       35

The formula for calculating the maximum for short exposure is:

              temperature (°C) - Clog time (min) - a}/b

     To solve the equation we must select a maximum time limitation on this
maximum for short exposure.  Since the MWAT is a weekly mean temperature
an appropriate length of time for this limitation for short exposure would
be 24 hr without risking violation of the MWAT.

     Since the time is fixed at 24 hr (1,440 min), we need to solve for
temperature by using, for example, the above acclimation temperature of 30° C
for which a = 32.1736 and b = -0.7811.
                       ,0 _    log 1.440 -a
          temperature  (° C) = —s—£	

                       ro r^^   3.1584  -32.1736     -29.0152
          temperature  (° C) - 	_Q>7811	  =  -0.7811   '=  37'146

Upon solving for each of the four data points we obtain 37,1°, 37.8°, 35.9°, and
38.4° C.  The average would be 37.3° C, and after subtracting the 2° C safety
factor to provide 100 percent survival, the short-term maximum for channel
catfish would be 35° C as appears in Table 1.

MAXIMUM WEEKLY AVERAGE TEMPERATURE FOR SPAWNING

     From the data sheets in Apendix C one would use either the optimum
temperature for spawning or, if that is not available, the middle of the range
of temperatures for spawning.  Again, if we use the channel catfish as an example,
the MWAT for spawning would be 27° C (Table 2).  Since spawning may occur over
a period of a few weeks or months in a particular water body and only a MWAT
for optimum spawning is estimated, it would be logical to use that optimum for
the median time of the spawning season.  The MWAT for the next earlier month

could approximate the lower temperature of the range in spawning temperature,
and the MWAT for the last month of a 3-month spawning season could approximate
the upper temperature for the range.  For example, if the channel catfish
spawned from April to June the MWAT's for the 3 months would be approximately
21°, 27°, and 29° C.  For fall spawning fish species the pattern or sequence
of temperatures would be reversed because of naturally declining temperatures
during their spawning season.

SHORT-TERM MAXIMUM DURING SPAWNING SEASON

     If spawning season maxima could be determined in the same manner as those
for the growing season, we would be using the time-temperature equation and
the Appendix B data as before.  However, growing  season data are based usually
on survival of juvenile and adult individuals.  Egg-incubation temperature
requirements are more restrictive (lower), and this biological process would
not be protected by maxima based on data for juvenile and adult fish.  Also,
spawning itself could be prematurely stopped if those maxima were achieved.
For most species the maximum spawning temperature approximates the maximum
successful incubation temperature.  Consequently, the short-term maximum
temperature should preferably be based on maximum incubation temperature for
successful embryo survival, but the maximum temperature for spawning is an
acceptable alternative.  In fact, the higher of the two is probably the
preferred choice as variability in available data has shown discrepancies in
this relationship for some species.

     For the channel catfish (Appendix C)_ the maximum reported incubation
temperature is 28° C, and the maximum reported spawning temperature is 29° C,
Therefore, the best estimate of the short-term survival of embryos would be
29° C (Table 2).

MAXIMUM WEEKLY AVERAGE TEMPERATURE FOR WINTER

     As discussed earlier the MWAT for winter is designed usually to prevent
fish deaths in the event the water temperature drops rapidly to an ambient
condition.  Such a temperature drop could occur as the result of a power-plant
shutdown or a movement of the fish itself.  These MWAT's are meant to apply
wherever fish can congregate, even if that is within the mixing zone.

     Yellow perch require a long chill period during the winter for optimum
egg maturation and spawning (Appendix A).  However, protection of this species
would be outside the mixing zone.  In addition, the embryos of fall spawning
fish such as trout,  salmon, and other related species such as cisco require
low incubation temperatures.   For these species also the MWAT during winter
would have to consider embryo survival, but again, this would be outside the
mixing zone.  The mixing zone, as used in this report,  is that area adjacent
to the discharge in which receiving system water quality standards do not
apply;  a thermal plume therefore is not a mixing zone.

     With these exceptions in mind,  it is unlikely that any signficant
effects on fish populations would occur as long as death was prevented.
                                       17

-------
 In many instances  growth could be  enhanced by controlled winter heat addition,
 but inadequate  food may result in  poor condition of  the fish.

      There are  fewer  data for lower incipient lethal temperatures than for
 the previously  discussed upper incipient lethal temperatures.   Appendix B
 contains lower  incipient lethal temperature data for only about 20 freshwater
 fish species, less than half of which are listed in  Tables  1 and 2.   Consequently,
 the available data were combined to calculate a regression  line (Figure 1)
 which gives a generalized MWAT for winter survival instead  of  the species
 specific approach used in the other types of criteria.

      All the lower incipient lethal temperature data  from Appendix C for
 freshwater fish species were used  to calculate the regression  line,  which had
 a slope of 0.50 and a correlation coefficient of 0.75.  This regression line
 was then displaced by approximately 2.5° C since it passed  through the middle
 of  the  data and did not represent the more sensitive  species.   This  new line
 on  the  edge of  the data array was then displaced by a 2° C  safety factor,  the
 same factor discussed earlier, to account for the fact that the  original data
 points  were for 50 percent survival and the 2° C safety factor would result
 in  100  percent  survival.   These two adjustments  in the original  regression
 line therefore  result in a line CFigure 11 that  should insure no  more  than
 negligible mortality of any fish species.  At lower acclimation  temperatures
 the  coldwater species were different from the warmwater species,  and the  resultant
 criterion  takes this into account.

     If fish can congregate in an area close  to  the discharge point,  this
 criterion could be a limit on the degree rise permissible at a particular  site.
 Obviously, if there is a  screened discharge channel in which some cooling
 occurs, a higher initial  discharge temperature could  be permissible  to  fish.

     An example of the use of this  criterion  (as plotted in the nomograph,
 Figure 1) would  be a  situation in which the ambient water  temperature  is 10°
 C, and the MWAT, where fish  could  congregate,  is 25°  C,  a  difference of 15°
C.  At a lower ambient temperature  of  about 2.5° C, the MWAT would be  10°  C
a 7.5° C difference.

                                   EXAMPLES

     Again, because precise thermal-effects data are not available for all
 species, we would like to emphasize the necessity for subjective decisions
 based on common-sense knowledge of existing aquatic systems.  For some
 fish species for which few or only relatively poor data are available,
 subjectivity becomes important.  If several qualified people were to calculate
 various temperature criteria for species for which several sets of hi&h quality
 data were available, it is unlikely that they would be in agreement in all
 instances.

     The following examples for warmwater and coldwater species are presented
 only as examples and are not at all intended to be water-body-specific
 recommendations.  Local extenuating circumstances may warrant differences, or
 the basic conditions of the examples may be slightly unrealistic.  More
 precise estimates of principal spawning and growth seasons should be
 available from the local state fish departments.

 EXAMPLE 1

     Tables 1 and 2, Figure 1, and Appendix C are the principal data sources
 for the criteria derived for this example.  The following water-body-specific
 data are necessary and in this example are hypothetical:

     1.   Species to be protected by the criteria:  channel catfish, largemouth
 bass, bluegill,  white crappie, freshwater drum, and bigmouth buffalo.

     2.   Local spawning seasons for these species:  April to June for the
 white crappie and the bigmouth buffalo; other species, May to July.

     3.   Normal ambient winter temperature:   5° C in December and January;
 10° C in November,  February, and March.

     4.   The principal growing season for these fish species:  July through
 September.

     5.   Any local extenuating circumstances should be incorporated into the
 criteria as  appropriate.   Some examples would be yellow perch gamete
maturation  in the winter,  very temperature-sensitive endangered species,
or important fish-food organisms that are very temperature sensitive.  For
 the example  we will have no extenuating circumstances.
                                      20

-------
     In some instances the data will be insufficient to determine each
necessary criterion for each species.  Estimates must be made based on
available species-specific data or by extrapolation from data for species with
similar requirements for which adequate data are available.  For instance, this
example includes the bigmouth buffalo and freshwater drum for which no growth
or short-term summer maxima are available (Table 1).  One would of necessity
have to estimate that the summer criteria would not be lower than that for the
white crappie, which has a spawning requirement as low as the other two
species.

     The choice of important fish species is very critical.  Since in this
example the white crappie is as temperature sensitive as any of the species,
the maximum weekly average temperature for summer growth is based on the
white crappie.  Consequently, this criterion would result in lower than
optimal conditions for the channel catfish,  bluegill, and largemouth bass.
An alternate approach would be to develop criteria for the single most
important species even if the most sensitive is not well protected.  The
choice is a socioeconomic one.

     Before developing a set of criteria such as those in Table 3, the material
material in Tables 1 and 2 should be studied for the species of concern.   It  is
evident that the lowest optimum temperature for summer growth for the species
for which data are available would be for the white crappie (28° C).  However,
there is no maximum for short exposure since the data are not available (Appendix
C) .  For the species for which there are data, the lowest maximum for short
exposure is for the largemouth bass (34° C).  In this example we have all
the necessary data for spawning and maximum for short exposure for embryo
survival for all species of concern (Table 2)..

     During the winter, criteria may be necessary both for the mixing zone as
well as for the receiving water.  Receiving-water criteria would be necessary
if an important fish species were known to have gamete-maturation requirements
like the yellow perch, or embryo-incubation requirements like trout, salmon,
cisco, etc.  In this example there is no need for receiving-system water criteria.

     At this point,  we are ready to complete Table 3 for Example 1.

                                       HEAT  AND  TEMPERATURE
   Living organisms do not respond to the quantity of heat
 but to degrees of temperature  or to temperature changes
 caused by transfer of heat. The importance of temperature
 to acquatic organisms is well known,  and the composition
 of aquatic communities depends largely on the temperature
 characteristics of their environment. Organisms have upper
 and lower  thermal tolerance limits,  optimum temperatures
 for growth, preferred temperatures in thermal  gradients,
 and temperature limitations for migration, spawning, and
 egg incubation.  Temperature  also  affects  the physical
 environment of the aquatic medium, (e.g., viscosity, degree
 of ice cover,  and oxygen capacity.  Therefore,  the  com-
 position of aquatic communities depends largely on tem-
 perature  characteristics of the  environment.   In  recent
 years there has been an accelerated demand for cooling
 waters  for power stations that release large quantities of
 heat, causing, or threatening to cause, either a warming of
 rivers, lakes, and coastal waters, or a rapid cooling when the
 artificial sources of heat are abruptly terminated. For these
 reasons, the environmental consequences  of temperature
 changes must be considered in assessments of water quality
 requirements of aquatic organisms.
   The  "natural"  temperatures of surface  waters of  the
 United States vary from 0 C to over 40 G as a function of
 latitude, altitude, season,  time of day,  duration of flow,
 depth, and many other variables. The agents that  affect
 the natural temperature are so  numerous that it  is unlikely
 that two bodies of water,  even in the  same latitude, would
 have exactly the same thermal characteristics. Moreover, a
 single aquatic habitat  typically does  not have uniform or
 consistent  thermal characteristics.  Since all aquatic  or-
 ganisms  (with  the  exception of aquatic mammals and  a
 few large, fast-swimming fish) have body temperatures that
 conform to the water temperature, these natural variations
 create  conditions  that  are optimum at  times, but  are
 generally  above or  below optima  for. particular physio-
 logical,  behavioral, and competitive functions of  the species
 present.
  Because  significant temperature changes may affect the
 composition  of an  aquatic  or  wildlife  community, an
 induced change in the thermal characteristics of an eco-

*From:National  Academy of Sciences  (1973)
 system may be detrimental.  On the other hand, altered
 thermal characteristics may be beneficial, as evidenced in
 most  fish  hatchery practices  and  at  other aquacultural
 facilities. (See the discussion of Aquaculture in Section IV.)
   The general difficulty in developing suitable criteria for
 temperature (which would limit the addition of heat) lies
 in determining the deviation from "natural" temperature a
 particular body of water can experience without suffering
 adverse effects  on its  biota. Whatever  requirements are
 suggested, a "natural" seasonal  cycle must be  retained,
 annual  spring and fall changes  in  temperature must  be
 gradual,  and  large  unnatural  day-to-day  fluctuations
 should be  avoided. In view of the many variables, it seems
 obvious that no  single temperature requirement can  be
 applied uniformly to  continental or large regional areas;
 the requirements must be closely related to each body of
 water  and  to  its  particular  community  of organisms,
 especially  the important  species found in it. These should
 include invertebrates,  plankton, or other plant and animal
 life that may be of importance to food chains or otherwise
 interact with species of direct interest to man. Since thermal
 requirements of various species differ,  the social  choice of
 the species to be protected allows  for different "levels of
 protection" among water bodies as suggested by DoudorofT
 and Shumway (1970)272 for dissolved oxygen criteria. (See
 Dissolved  Oxygen, p. 131.) Although such decisions clearly
 transcend  the scientific judgments  needed  in establishing
 thermal criteria for protecting selected species, biologists can
 aid in  making them.  Some measures useful in  assigning
 levels of importance to species  are:  (1) high yield to com-
 mercial or sport fisheries, (2) large  biomass in the existing
 ecosystem (if desirable), (3) important links in food chains
 of other species judged important  for other reasons, and
 (4) "endangered" or  unique status. If it  is desirable to
 attempt strict preservation of an existing  ecosystem, the
 most  sensitive species  or  life stage may dictate the criteria
 selected.
   Criteria for  making recommendations  for water  tem-
 perature to protect desirable aquatic life cannot be simply a
 maximum allowed change  from "natural temperatures."
 This is principally because a change of even one degree from

152/Section III—Freshwater Aquatic Life and Wildlife
an  ambient  temperature has varying  significance for an
organism,  depending upon where the ambient level lies
within the tolerance range. In addition, historic tempera-
ture records or, alternatively, the existing ambient tempera-
ture prior to any thermal alterations by man are not always
reliable  indicators  of  desirable  conditions  for  aquatic
populations. Multiple developments of water resources also
change water temperatures both  upward (e.g., upstream
power plants  or shallow reservoirs) and downward  (e.g.,
deep water releases from large reservoirs), so that "ambient"
and "natural" are exceedingly difficult to define at a given
point over periods of several years.
  Criteria for temperature should consider both the multiple
thermal requirements of aquatic species and requirements
for  balanced communities. The number of distance require-
ments and the necessary values for each require  periodic
reexamination as knowledge of thermal effects  on aquatic
species  and  communities  increases.   Currently definable
requirements include:

    • maximum  sustained  temperatures that are  con-
       sistent  with maintaining desirable  levels  of pro-
       ductivity ;
    • maximum levels of metabolic acclimation to warm
       temperatures that will permit  return  to  ambient
       winter temperatures  should  artificial  sources of
       heat cease;
    • temperature limitations for survival of brief exposures
       to temperature extremes, both upper and lower;
    • restricted temperature ranges  for various stages of
       reproduction, including (for fish) gonad growth and
       gamete maturation, spawning migration, release of
       gametes,  development of the  embryo,  commence-
       ment of independent  feeding (and other activities)
       by juveniles; and temperatures required for meta-
       morphosis,  emergence, and other activities  of lower
       forms;
    • thermal limits for diverse compositions of species of
       aquatic communities, particularly where reduction
       in  diversity creates  nuisance  growths  of  certain
       organisms,  or where  important  food  sources or
       chains  are altered;
    • thermal  requirements  of downstream aquatic life
       where upstream warming of a cold-water source will
       adversely affect  downstream temperature  require-
       ments.

  Thermal criteria must also be formulated with knowledge
of how man alters temperatures, the hydrodynamics of the
changes, and how  the biota can reasonably be expected to
interact  with the  thermal regimes produced. It is not
sufficient, for  example,  to define only  the thermal criteria
for  sustained production of a species in open waters, because
large  numbers of organisms may also be exposed to thermal
changes  by being  pumped  through the condensers  and
mixing  zone  of a power plant.   Design  engineers  need
particularly to know  the biological limitations to their
design options in such instances. Such considerations may
reveal nonthermal impacts of cooling processes that may
outweigh temperature  effects, such as impingement of fish
upon intake screens, mechanical or chemical  damage to
zooplankton in  condensers, or effects of altered current
patterns on bottom fauna in a discharge area. The environ-
mental situations of aquatic organisms (e.g., where they
are,  when they are there, in what numbers) must also be
understood. Thermal criteria for migratory  species should
be applied to a certain area only when the species is actually
there.  Although  thermal  effects  of power stations  are
currently of great interest,  other  less  dramatic causes of
temperature change  including deforestation,  stream chan-
nelization,  and impoundment of  flowing water must  be
recognized.

DEVELOPMENT  OF CRITERIA

  Thermal criteria necessary for the protection of species or
communities are discussed separately below.  The order of
presentation of the different criteria does not imply priority
for any one body of water. The descriptions define preferred
methods and procedures for judging thermal requirements,
and  generally do not give numerical  values  (except in
Appendix II-C). Specific values for all limitations would
require a biological handbook  that is far beyond the scope
of this Section.  The  criteria may seem complex, but they
represent an extensively developed framework of knowledge
about  biological responses. (A sample application of these
criteria begins on page 166, Use of Temperature Criteria.)

TERMINOLOGY  DEFINED

  Some basic thermal  responses of aquatic organisms will
be referred to repeatedly and  are defined  and reviewed
briefly here.  Effects of heat  on organisms  and  aquatic
communities have been reviewed periodically (e.g., Bullock
1955,269 Brett 1956;253 Fry 1947,276 1964,278 1967;279  Kinne
1970296). Some effects have been analyzed in the context of
thermal modification by power plants (Parker and Krenkel
1969;308 Krenkel and Parker 1969;298 Cairns  1968;261 Clark
1969;263 and Coutant 1970c269). Bibliographic information
is available from Kennedy and Mihursky (1967),294  Raney
and  Menzel (1969),313  and from annual reviews published
by  the Water  Pollution  Control  Federation (Coutant
1968,265 1969,266  1970a,267  1971270).
  Each species (and often each distinct life-stage of a species)
has a  characteristic  tolerance range of temperature as a
consequence of acclimations (internal biochemical  adjust-
ments) made while at previous holding temperature (Figure
III-2; Brett 1956253). Ordinarily, the ends of this range, or
the lethal thresholds, are defined by survival of 50 per cent
of a  sample of individuals. Lethal thresholds typically are
referred to as "incipient  lethal  temperatures," and tem-
perature  beyond  these ranges would be considered "ex-
                                                      29

 treme."  The  tolerance range is adjusted  upward by ac-
 climation to warmer water and downward to cooler water,
 although there  is a  limit to such  accommodation. The
 lower end of the range usually is at zero degrees centigrade
 (32 F) for species in temperate latitudes (somewhat less for
 saline waters),  while the upper end terminates in  an
 "ultimate incipient lethal temperature" (Fry et al.  1946281).
 This  ultimate threshold temperature represents the "break-
 ing point"  between the  highest temperatures  to which an
 animal can be acclimated and  the  lowest of the  extreme
 temperatures  that will kill the warm-acclimated organism.

to a few hours will not greatly affect the thermal tolerance
limits, since acclimation to changing temperatures requires
several days (Brett 1941).261
  At the temperatures above and below the incipient lethal
temperatures, survival depends not only on the temperature
but also on the duration of exposure, with mortality oc-
curring more rapidly the farther the  temperature is from
the threshold (Figure III-3). (See*Coutant 1970am and
1970b268 for  further  discussion  based  on both  field and
laboratory studies.)  Thus, organisms  respond to extreme
high  and low  temperatures in a  manner similar to the
dosage-response pattern which is  common to  toxicants,
Pharmaceuticals, and radiation (Bliss 1937).249 Such tests
seldom extend beyond one week in duration.

MAXIMUM ACCEPTABLE  TEMPERATURES FOR
PROLONGED EXPOSURES

  Specific criteria for prolonged exposure (1 week or longer)
must  be defined for warm and for cold seasons. Additional
criteria for gradual  temperature (and life cycle) changes
during reproduction and  development  periods  are dis-
cussed on pp. 162-165.

 154: /Section Hi—Freshwater Aquatic Life and Wildlife
 SPRING, SUMMER, AND FALL MAXIMA FOR
 PROLONGED  EXPOSURE

   Occupancy  of habitats  by most aquatic organisms  is
 often limited within the thermal tolerance range to tem-
 peratures  somewhat below the ultimate upper incipient
 lethal temperature. This is the result of poor physiological
 performance at near lethal levels (e.g., growth, metabolic
 scope for  activities, appetite, _food conversion efficiency),
• interspecies  competition, disease,  predation,  and  other
 subtle ecological factors  (Fry  195 1;277  Brett 197 1266). This
 complex limitation is evidenced by restricted southern and
 altitudinal distributions of many species. On the other hand,
 optimum  temperatures   (such as those  producing fastest
 growth rates)  are  not generally necessary at all times to
 maintain thriving  populations and are often exceeded in
 nature during summer months  (Fry 1951 ;277 Cooper 1953 ;264
 Beyerle and Cooper I960;246 Kramer and Smith I960297).
 Moderate  temperature  fluctuations  can  generally  be
 tolerated as long as a maximum upper limit is not exceeded
 for long periods.
   A true temperature limit for exposures long enough to
 reflect metabolic acclimation and optimum ecological per-
 formance  must lie  somewhere between  the physiological
 optimum and the ultimate upper incipient lethal tempera-
 tures.  Brett (I960)254 suggested that  a  provisional long-
 term exposure limit be the temperature greater than opti-
 mum  that allowed  75 per  cent of optimum performance.
 His suggestion has not been tested by definitive studies.
   Examination of literature  on  performance,  metabolic
 rate,  temperature preference, growth, natural distribution,
 and tolerance of several species has yielded  an apparently
 sound theoretical basis for estimating an upper temperature
 limit for long term exposure and a method for doing this
with  a minimum of additional research. New data will
provide refinement, but this method forms a useful guide
for the present time. The method is based on the general
observations summarized here and in Figure 1 1 1-4 (a,  b, c).
   1 .  Performances of organisms over a range of tempera-
tures are available in the scientific literature for a variety of
functions. Figures III-4a and  b show  three characteristic
types of responses numbered 1  through  3, of which types  1
and 2 have coinciding  optimum peaks.  These optimum
temperatures are characteristic for a species  (or life stage).
   2.  Degrees  of  impairment from  optimum  levels  of
various performance functions  are  not uniform  with in-
creasing temperature above the  optimum for a single species.
The most sensitive function appears to  be growth rate, for
which a temperature of zero growth (with abundant food)
can be determined  for important species and  life stages.
Growth rate of organisms appears to be an integrator of all
factors acting on an organism. Growth rate should probably
be expressed as net biomass gain or net growth  (McCormick
et al.  197 1)302 of the population, to account for deaths.
  3.  The maximum temperature at which several species
 are consistently found  in nature  (Fry 1951;277  Narver
 1970)306 lies near the average of the optimum temperature
 and the temperature of zero net growth.
   4.   Comparison of patterns in  Figures  III-4a and b
 among different species indicates that while the trends are
 similar,  the optimum is closer to the lethal level in  some
 species than it is in sockeye salmon. Invertebrates exhibit a
 pattern  of temperature effects on growth rate that is very
 similar to that of fish (Figure  III-4c).
   The optimum temperature  may be influenced by rate of
 feeding. Brett et al. (1969)267  demonstrated  a shift in opti-
 mum toward  cooler temperatures for sockeye salmon when
 ration was restricted. In a similar experiment with channel
 catfish, Andrews and Stickney (1972)242 could see no such
 shift. Lack of a general shift  in optimum may  be due to
 compensating changes in activity of the fish (Fry personal
 observation).^6
   These observations suggest  that an average of the  opti-
 mum temperature and the temperature of zero net growth
 [(opt. temp. + z.n.g. temp)/2] would be a useful estimate of
 a limiting weekly mean temperature for  resident organisms,
 providing  the peak  temperatures  do  not  exceed values
 recommended for short-term  exposures.  Optimum growth
 rate would generally be reduced to no lower than 80 per cent
 of the  maximum if the limiting temperature is as averaged
 above  (Table  III-ll). This range of reduction from  opti-
 mum appears acceptable, although there are no quantita-
 tive studies available that would  allow  the criterion to be
 based upon a  specific level of impairment.
  The criteria for maximum upper temperature must allow
for seasonal changes, because  different life stages of many
species  will have  different thermal requirements for the
average  of their optimum  and zero net growths. Thus a
juvenile fish in May will be likely to have a lower maximum
acceptable temperature than will the same fish in July, and
this must be reflected in the thermal criteria for a waterbody.

 (Brett 1952)262 whereas those for zero growth are not.

 z.n.g. temp.)/2. For example, the values are, respectively,
 32.7 and 32.8 C for channel catfish and 30.6 and 30.8 for
 largemouth bass (data from Table III-8 and Appendix II).

able limits, while retaining as its scientific basis the require-
ments of preserving adequate rates of growth. Some limits
obtained from data in the  literature  are  given  in  Table
111-12. A hypothetical example of the effect of this limit on
growth of largemouth bass is illustrated in  Figure III-5.
  Figure III-5 shows a hypothetical example of the  effects
of the limit on maximum weekly average  temperature on
growth rates of juvenile largemouth bass. Growth data as a
function of temperature are from Strawn 1961319; the  ambi-
ent temperature is an averaged  curve for Lake  Norman,
N. C., adapted from data supplied by Duke Power  Com-
pany. A  general temperature elevation of  10 F is used to
provide an extreme example.  Incremental  growth rates
(mm/wk) are  plotted on the main figure, while annual ac-
cumulated growth is plotted in the inset.  Simplifying as-
sumptions were that growth rates and the relationship of
growth rate to temperature were constant  throughout the
year, and that there would be sufficient  food  to sustain
maximum attainable growth rates at all times.
  The criterion for a specific location would be determined
by the most  sensitive  life stage  of an important species
likely to  be present in that location  at that time.  Since
many fishes have  restricted  habitats  (e.g., specific  depth
zones) at  many life stages, the thermal criterion must be
applied to the proper zone. There is field evidence that fish
avoid localized areas of unfavorably warm  water. This has
been  demonstrated both in lakes  where  coldwater fish
normally  evacuate warm  shallows  in summer (Smith
1964)318  and  at power station mixing zones (Gammon
1970;282 Merriman et al. 1965).304 In most large  bodies of
water  there are both vertical  and  horizontal  thermal
gradients  that mobile  organisms  can follow  to avoid un-
favorable high (or low)  temperatures.
  The summer maxima need  not, therefore,   apply  to
mixing zones that occupy a small percentage of the suitable
habitat or  necessarily to all zones where organisms have
free egress to cooler water. The maxinja must apply, how-
ever, to restricted local habitats, such as lake hypolimnia or
thermoclines,  that provide  important summer  sanctuary
areas for cold-water species. Any avoidance of a warm area
not part of the normal  seasonal habitat of  the species will
mean that less  area of the water body is available to support
the population and that production may be reduced. Such
reduction should not interfere with biological communities
or populations of  important species to a  degree that is
damaging to the ecosystem  or other beneficial  uses.  Non-
mobile organisms that must  remain in  the warm  zone will
probably be the limiting organisms for that location. Any
recommendation for upper limiting temperatures must be
applied carefully with  understanding of the population
dynamics  of the species in question in order to  establish
both local and regional requirements.

  Heat added to upper reaches of some cold rivers can be
retained throughout the river's remaining length (Jaske
and Synoground 1970).292 This factor adds to the natural
trend of warming at distances from headwaters. Thermal
additions in  headwaters, therefore,  may  contribute  sub-
stantially to reduction of cold-water species in downstream
areas (Mount 1970).305 Upstream thermal additions should
be evaluated  for their effects on summer maxima at down-
stream locations, as well as in the immediate vicinity  of
the heat source.

Recommendation

  Growth of  aquatic organisms would be main-
tained at levels  necessary for sustaining  actively
growing and reproducing populations if the maxi-
mum weekly average temperature in the zone in-
habited by the species at that time does not exceed
one-third of the range between the optimum tem-
perature and the ultimate upper incipient  lethal
temperature of the species (Equation 1, page 157),
and the temperatures above the weekly average do
not exceed the criterion for  short-term exposures.
This maximum need not apply to acceptable mix-
ing zones (see proportional relationships of mixing
zones to receiving  systems, p.  114), and  must be
applied with adequate understanding of the normal
seasonal distribution of the important species.
WINTER MAXIMA

  Although  artificially produced temperature elevations
during winter months may actually bring the temperature
closer to optimum or preferred temperature for important
species and  attract fish  (Trembley  1965),321 metabolic
acclimation to these higher levels can preclude safe return
of the organism  to ambient  temperatures  should  the
artificial heating suddenly cease (Pennsylvania Fish Com-
mission 1971;310 Robinson  1970)316 or  the organism  be
driven from  the heat area.  For example, sockeye salmon
(Oncorhynchus nerka) acclimated to 20 C suffered 50 percent
mortality in  the laboratory when  their temperature was
dropped suddenly to 5 C (Brett  1971:256 see Figure III-3).
The same population of fish withstood a drop to zero when
acclimated to 5 C. The lower limit of the range of thermal
tolerance of  important  species must, therefore, be main-
tained at the  normal  seasonal  ambient temperatures
throughout cold seasons, unless special provisions are made
to assure that rapid temperature drop will not occur or that
organisms cannot become acclimated to elevated tempera-
tures.  This can be accomplished  by limitations on tempera-
ture elevations in such areas as discharge canals and mixing
zones  where organisms may reside, or  by insuring that
maximum temperatures occur only in  areas not accessible
to important aquatic life for lengths of time  sufficient to
allow  metabolic acclimation. Such inaccessible  areas would
include the high-velocity zones of diffusers or screened dis-
                                                   37

 charge channels. This reduction of maximum temperatures
 would not preclude use of slightly warmed areas as sites for
 intense winter fisheries.
   This consideration may be important in some regions at
 times other  than in winter. The Great Lakes, for example,
 are susceptible to rapid changes in elevation of the thermo-
 cline in summer  which  may induce  rapid decreases in
 shoreline temperatures. Fish acclimated to exceptionally
 high temperatures in discharge canals may be killed or
 severely  stressed  without  changes in power plant opera-
 tions (Robinson 1968).314  Such regions should  take special
 note of this  possibility.
   Some  numerical values for acclimation temperatures and
 lower  limits of tolerance ranges (lower  incipient lethal
 temperatures) are given in Appendix II-C. Other data must
 be provided by further research.  There  are no adequate
 data available with which to estimate a safety factor for no
 stress from cold shocks. Experiments currently in progress,
 however, suggest that channel catfish fingerlings are more
 susceptible to predation after being cooled more than 5 to
 6 C (Goutant, unpublished data).324
   The effects of limiting ice formation in lakes and rivers
 should  be carefully observed.  This aspect of maximum
 winter temperatures is apparent,  although there is insuffi-
 cient evidence to  estimate its importance.

 Recommendation

   Important species  should  be protected  if  the
 maximum weekly average temperature during win-
 ter  months in any area to which they have access
 does  not   exceed  the  acclimation  temperature
 (minus a 2 C safety factor)  that raises the lower
 lethal threshold temperature of such species above
 the normal ambient water temperatures for  that
 season, and the criterion for  short-term exposures
 is not exceeded. This  recommendation applies es-
 pecially to locations where organisms may be at-
 tracted from the receiving water and subjected to
 rapid thermal drop, as in the low velocity areas of
 water diversions (intake or discharge), canals, and
 mixing  zones.

 SHORT-TERM EXPOSURE  TO  EXTREME TEMPERATURE

  To protect aquatic life  and yet allow other uses of the
water, it is essential to know the lengths of time organisms
can survive  extreme temperatures (i.e., temperatures that
exceed  the   7-day incipient  lethal temperature).  Both
natural environments and  power plant cooling  systems can
briefly reach temperature extremes (both upper and lower)
without  apparent  detrimental  effect to  the  aquatic life
 (Fry 1951 ;277 Becker et al. 1971).245
  The length of time that 50 per  cent of a population will
survive temperature above the incipient lethal temperature
can  be calculated from a regression equation of experi-
mental data (such as those in Figure 111-3) as follows:

               log (time) =a+b (temp.)     (Equation 2)

where time is expressed in minutes, temperature in degrees
centigrade and where a  and b  are intercept  and slope,
respectively, which  are characteristics of each acclimation
temperature  for  each species. In some  cases the  time-
temperature relationship is more complex than the  semi-
logarithmic model given above.  Equation 2,  however, is
the  most applicable,  and is generally accepted by  the
scientific  community  (Fry   1967).279 Caution  is recom-
mended  in extrapolating beyond the data limits of  the
original research (Appendix II-C). The rate of temperature
change does not appear to alter this equation, as long as the
change occurs more rapidly than  over several days (Brett
1941.251  Lgrnke  1970).30° Thermal  resistance  may  be
diminished by the  simultaneous  presence  of toxicants or
other debilitating factors (Ebel et al. 1970,273 and summary
by Coutant 1970c).269 The most accurate predictability can
be derived from  data collected using water from the site
under evaluation.
  Because the  equations based on  research on  thermal
tolerance predict 50  per cent mortality, a safety factor is
needed to assure no mortality. Several studies  have  indi-
cated that a 2 C  reduction of an  upper stress temperature
results in no  mortalities within  an equivalent  exposure
duration  (Fry et al.  1942;280 Black 1953).248 The validity
of a two degree safety factor was strengthened by the results
of Coutant  (1970a).267 He showed that about 15 to 20
per cent of the exposure time, for median mortality at a given
high temperature, induced selective predation on thermally
shocked salmon and trout. (This also amounted to reduction
of the effective  stress temperature  by about  2  C.)  Un-
published data  from subsequent predation experiments
showed that this reduction of about 2 C also applied to the
incipient lethal temperature. The level at which there is no
increased vulnerability to predation is the best estimate of a
no-stress exposure that is currently available.  No similar
safety  factor has  been explored for tolerance of low  tem-
peratures. Further  research  may determine  that  safety
factors, as well  as  tolerance limits, have  to  be decided
independently for each species, life stage, and water quality
situation.
  Information needed for predicting survival of a number
of species of fish and invertebrates  under short-term condi-
tions of heat extremes is presented  in Appendix  II-C. This
information  includes  (for each acclimation temperature)
upper  and lower incipient lethal temperatures: coefficients
a and b for the thermal resistance equation; and information
on size,  life stage, and geographic source  of the species.
It is  clear that adequate data  are available for only a small
percentage of aquatic species, and additional research is
necessary.  Thermal  resistance  information  should  be
obtained  locally  for critical  areas to account  for simul-
                                                      38

taneous presence  of toxicants or other debilitating factors,
a consideration not reflected in Appendix II-C data. More
data are available for upper lethal temperatures than for
lower.
  The resistance  time   equation,  Equation  2,  can  be
rearranged to incorporate the 2 C margin of safety and also
to define conditions for survival (right side of the equation
less than or equal to 1) as follows:
                   1  >
                           time
                       JQ[a+b(temp.+2)]
(Equation 3)
  Low levels of mortality of some aquatic organisms are not
necessarily detrimental to ecosystems, because permissible
mortality levels can  be established. This is how  fishing or
shellnshing activities are  managed. Many states and inter-
national agencies  have  established elaborate systems for
setting an allowable rate of mortality (for sport  and com-
mercial fish) in order to assure needed reproduction and
survival. (This should not imply, however, that  a form of
pollution should be allowed to take the entire harvestable
yield.) Warm discharge  water from  a  power plant  may
sufficiently stimulate reproduction of some organisms (e.g.,
zooplankton),  such that those killed during passage through
the maximally heated areas are replaced within a few hours,
and no impact of the mortalities can be found in the open
water  (Churchill  and  Wojtalik  1969;262  Heinle 1969).288
On the other  hand, Jensen  (1971)293  calculated  that  even
five percent additional  mortality  of 0-age brook  trout
(Salvelinus fontinalis) decreased the yield of the trout fishery,
and 50 per cent additional mortality would,  theoretically.
cause extinction of the population. Obviously, there can be
no adequate generalization concerning the impact of short-
term  effects on entire ecosystems,  for  each case will be
somewhat  different. Future  research  must be directed
toward determining the effects of local temperature stresses
on population dynamics.  A complete discussion will not be
attempted here. Criteria for complete short-term protection
may not always be necessary and should  be applied with an
adequate understanding of local conditions.

Recommendation
  Unless  there  is justifiable reason  to believe it
unnecessary for maintenance of populations of a
species,  the  right side  of Equation  3  for  that
species should not  be allowed  to increase above
unity when the temperature exceeds the incipient
lethal temperature minus 2 C:
                  1 >
                          time
                       JQ[u+6(temp.+2)]
Values for a and b at the appropriate acclimation
temperature for some species can be obtained from
Appendix II-C or  through  additional  research  if
necessary data are not available. This recommen-
dation applies to all locations where organisms to
be protected  are exposed, including areas  within
mixing zones and water diversions such as power
station cooling water.

REPRODUCTION AND DEVELOPMENT

  The sequence of events relating to gonad growth and
gamete maturation, spawning migration, release of gametes,
development of the egg  and embryo, and  commencement
of independent feeding represents one of the most complex
phenomena  in  nature, both for fish  (Brett 1970)265 and
invertebrates  (Kinne  1970).296 These events  are generally
the most thermally sensitive of all life stages. Other environ-
mental factors, such as light and salinity, often seasonal in
nature, can also profoundly affect the response to tempera-
ture  (Wiebe 1968).323 The general physiological state of the
organisms (e.g., energy reserves), which is an integration of
previous history, has a strong effect on reproductive poten-
tial (Kinne 1970).296 The erratic sequence of failures and
successes of different year classes of lake fish attests to the
unreliability of natural conditions for providing optimum
reproduction.
  Abnormal, short-term temperature fluctuations appear to
be of greatest significance in reduced production of juvenile
fish  and  invertebrates  (Kinne,  1963).296  Such  thermal
fluctuations can  be a  prominent consequence of water use
as in hydroelectric power (rapid changes in river flow rates),
thermal electric  power (thermal discharges at fluctuating
power levels),  navigation  (irregular  lock releases),  and
irrigation  (irregular water  diversions and wasteway re-
leases). Jaske and  Synoground (1970)292 have documented
such temperature changes due to  interacting thermal and
hydroelectric  discharges  on the Columbia  River.
  Tolerable limits  or variations  of temperature change
throughout development,  and particularly at the  most
sensitive  life  stages,  differ  among  species.  There  is  no
adequate summary of data on such thermal requirements
for successful reproduction. The data are scattered through
many years of natural history observations  (however, see
Breder and Rosen  1966250 for a recent compilation of some
data; also see Table 111-13).  High priority must be assigned
to summarizing existing information  and obtaining that
which is lacking.
  Uniform elevations of temperature by  a few degrees
during the spawning period, while maintaining short-term
temperature cycles and seasonal thermal  patterns, appear
to have little overall effect  on the reproductive  cycle of
resident aquatic species, other than  to advance the timing
for spring spawners or delay  it for fall spawners. Such shifts
are often seen in nature,  although no quantitative measure-
ments of  reproductive  success have  been  made in  this
connection.  For example,  thriving populations  of  many
fishes occur in diverse streams of the  Tennessee Valley in
which the date of the spawning temperature may vary in a
                                                     39

 given year by 22 to 65 days. Examination of the literature
 shows that shifts in spawning dates by nearly one month
 are common in natural waters throughout the U.S. Popula-
 tions of some species at the southern limits  of their dis-
 tribution are exceptions, e.g., the lake whitefish (Coregonus
 clupeajormis)  in  Lake  Erie  that require a prolonged, cold
 incubation period  (Lawler  1965)299  and species such  as
 yellow perch  (Percaflavescens) that  require a long chill period
 for egg maturation prior  to spawning  (Jones,  unpublished
   This biological plasticity suggests that the annual spring
 rise, or fall drop, in temperature might safely  be advanced
 (or delayed) by nearly one month in many regions, as long
 as the thermal requirements that  are necessary for migra-
 tion, spawning, and other activities are not  eliminated and
 the necessary chill periods, maturation times, or incubation
 periods are preserved for  important species. Production of
 food organisms may advance in a similar way, with little
 disruption of food chains, although there is little evidence to
 support this assumption (but see Coutant 1968;265 Coutant
 and Steele 1968;271 and Nebeker  1971).307  The process is
 similar to the latitudinal differences within the range of a
 given species.
   Highly  mobile species  that depend upon  temperature
 synchrony among widely different regions or environments
 for various phases of the reproductive or rearing cycle (e.g.,
 anadromous salmonids  or aquatic insects)  could  be faced
 with dangers of dis-synchrony if one area is warmed,  but
 another is not. Poor long-term success of one year class of
 Eraser River (British Columbia) sockeye salmon (Oncorhyn-
 chus nerka) was attributed to early (and highly successful)
 fry production and emigration during an abnormally warm
 summer  followed  by  unsuccessful,  premature  feeding
 activity in the cold and still unproductive estuary (Vernon
 1958).322 Anadromous species are  able, in some cases, (see
 studies of eulachon  (Thaleichthys  pacificus)  by Smith and
      Saalfeld 1955)317 to modify their migrations and spawning
      to coincide  with  the proper temperatures whenever  and
      wherever they occur.
        Rates of embryonic development that could lead to  pre-
      mature  hatching  are determined  by temperatures of the
      microhabitat of the embryo. Temperatures of the micro-
      habitat may be quite different from those of the remainder
      of the waterbody. For example, a thermal effluent at the
      temperature  of maximum water  density (approximately
      4 C) can sink in a  lake whose surface water  temperature
      is  colder  (Hoglund and  Spigarelli,  1972).290  Incubating
      eggs of such species as lake trout (Salvelinus namaycusK)  and
      various coregonids on the lake bottom may be intermittently
      exposed to temperatures warmer  than normal. Hatching
      may be advanced to dates that are too early for survival of
      the fry in their  nursery areas.  Hoglund and Spigarelli
      1972,290 using temperature data from a sinking plume  in
      Lake Michigan, theorized that if lake herring (Coregonus
      artedii)  eggs  had been  incubated at  the location of one  of
      their temperature  sensors,  the fry  would  have  hatched
      seven days early. Thermal limitations must, therefore, apply
      at the proper location for the particular species or life stage
      to be protected.
      Recommendations
        After their specific  limiting temperatures  and
      exposure times have been determined  by  studies
      tailored  to local conditions,  the reproductive  ac-
      tivity  of selected species will  be protected in areas
      where:
      • periods required  for  gonad growth and  gamete
        maturation are preserved;
      • no  temperature  differentials are created that
        block spawning migrations, although some delay
        or advancement of timing based upon local con-
        ditions may be tolerated;
                                                       41

-------
                                                                                    Heat and Temperature /165
• temperatures are not raised to a level at which
  necessary spawning or incubation temperatures
  of winter-spawning species cannot occur;
• sharp temperature changes are not induced  in
  spawning areas, either  in mixing zones or  in
  mixed water bodies (the thermal and geographic
  limits to such changes will be dependent upon
  local  requirements  of  species,  including  the
  spawning microhabitat,  e.g.,  bottom gravels,
  littoral zone,  and surface  strata);
• timing of reproductive events is not  altered  to
  the extent that synchrony is broken where repro-
  duction or rearing of certain life stages is shown
  to be dependent upon cyclic food sources or other
  factors at remote locations.
• normal patterns of gradual temperature changes
  throughout the year are maintained.

These requirements should supersede  all others
during times when they apply.

CHANGES IN STRUCTURE OF AQUATIC COMMUNITIES

  Significant change in temperature or in thermal patterns
over a period of time may cause some change  in the com-
position of aquatic communities (i.e., the species represented
and the numbers  of individuals in each species). This has
been documented by field studies at power plants (Trembley
1956-1960)321 and by laboratory investigations (Mclntyre
1968).303 Allowing temperature changes to alter significantly
the community  structure in  natural waters may be detri-
mental, even though species of direct importance to  man
are not eliminated.
  The limits of allowable change in species diversity due to
temperature changes should not differ from those applicable
to any other pollutant. This  general topic is treated  in
detail, in reviews  by others (Brookhaven  National Lab.
1969)258 and is  discussed in Appendix II-B, Community
Structure and Diversity Indices, p. 408.

NUISANCE ORGANISMS

  Alteration of aquatic communities by the addition of heat
may occasionally result in growths of nuisance organisms
provided that other  environmental conditions  essential  to
such growths (e.g.,  nutrients)  exist.  Poltoracka (1968)311
documented  the growth stimulation of plankton in  an
artificially heated small  lake;  Trembley  (1965321)  re-
ported dense growths of attached algae in the discharge
canal and shallow discharge plume of a power station (where
the  algae broke loose periodically releasing decomposing
organic matter to  the receiving water). Other  instances of
algal growths in effluent channels of power stations were
reviewed by Coutant (1970c).269
  Changed thermal patterns (e.g., in stratified lakes)  may
greatly alter the seasonal appearances  of  nuisance algal
growths even though the temperature changes are induced
by altered circulation patterns (e.g., artificial destratifica-
tion). Dense growths of plankton have been retarded in
some instances and stimulated in others (Fast 1968;276 and
unpublished data 1971).325
  Data  on temperature limits or thermal distributions in
which nuisance growths will be produced are not presently
available due in part to the complex interactions with other
growth stimulants. There is not  sufficient evidence to say
that  any temperature increase will necessarily  result in
increased nuisance organisms. Careful evaluation of local
conditions is required for any  reasonable prediction of
effect.

Recommendation
  Nuisance growths  of organisms  may  develop
where there are increases in temperature  or alter-
ations  of the temporal or spatial  distribution of
heat in water. There should be careful evaluation
of all factors contributing to nuisance growths at
any  site before  establishment of  thermal limits
based upon this response, and  temperature limits
should be set in conjunction with restrictions on
other factors (see the discussion of Eutrophication
and  Nutrients in Section I).

CONCLUSIONS
  Recommendations for  temperature  limits to  protect
aquatic life consist of the following two upper limits for any
time  of the year (Figure 111-6).

  1.  One limit consists of a maximum weekly average
temperature that:
    (a)  in  the warmer  months   (e.g.,  April  through
        October   in  the  North,  and  March  through
        November in the South) is one third of the range
        between   the  optimum  temperature  and  the
        ultimate upper incipient lethal temperature for the
        most sensitive important species (or  appropriate
        life stage)  that is normally found at that location at
        that time; or
    (b)  in the cooler months (e.g., mid-October to mid-
        April in the North, and December to February in
        the South) is that elevated temperature from which
        important species die when that elevated  tem-
        perature  is suddenly  dropped  to  the normal
        ambient  temperature, with the  limit being the
        acclimation temperature  (minus a  2 C  safety
        factor), when the lower  incipient lethal tempera-
        ture equals the normal ambient water temperature
        (in some regions this limit may also be applicable
        in summer); or
    (c)  during reproduction seasons (generally April-June
        and September-October in the North, and March-
        May and  October-November in the South) is that
                                                    42

        growths of nuisance organisms.
  2.  The second limit is the  time-dependent maximum
temperature  for short  exposures  as given by  the  species-
specific equation:

                        10[a+b(temp.+2)]

  Local requirements for reproduction  should supersede
all other requirements when they are applicable. Detailed
ecological  analysis  of  both  natural  and  man-modified
aquatic environments is necessary  to ascertain  when these
requirements should apply.
USE  OF TEMPERATURE CRITERIA

  A  hypothetical electric power station using lake water for
cooling is  illustrated as  a typical example in Figure III-7.
This discussion concerns the application of thermal criteria
to this typical situation.
  The size of the power station is  1,000 megawatts electric
(MWe) if nuclear, or 1,700 MWe  if fossil-fueled (oil,  coal,
gas); and it  releases  6.8  billion  British Thermal  Units
(BTU) per hour to the aquatic environment. This size  is
representative of power stations currently being installed.
Temperature  rise  at the condensers would be  20 F  with
cooling water flowing at the rate of 1,520 cubic feet/second
(ft3/sec)  or 682,000 gallons/minute.  Flow could be in-
creased to reduce temperature rise.
   The schematic Figure 111-7 is drawn with two alternative
discharge  arrangements to illustrate the extent to which
design features  affect thermal  impacts upon aquatic life

 168/Section Ill—Freshwater Aquatic Life and Wildlife
Warm condenser water can be carried from the station to
the lake by (a) a pipe carrying water at a high flow velocity
or (b) a canal in which the warm water flows slowly. There
is  little cooling in  a  canal,  as  measurements at several
existing power stations have shown. Water can be released
to the lake by using any of several combinations of water
velocity and  volume  (i.e., number  of outlets)  or outlet
dimensions and locations.  These  design features largely
determine  the configuration of the thermal plumes illus-
trated in Figure III-7 resulting from either rapid dilution
with lake water or from slow release as a surface layer. The
isotherms  were placed according to  computer simulation
of thermal discharges  (Pritchard 1971)312 and represent a
condition without lake currents to  aid  mixing.
  Exact configuration of an  actual plume depends  upon
many factors  (some of which change  seasonally or even
hourly) such as local patterns of currents, wind, and bottom
and shore topography.

Analytical Steps

  Perspective  of the organisms in the water body and of the
pertinent   non-biological  considerations (chemical,  hy-
drological,  hydraulic)  is an essential  beginning.  This
perspective requires  a  certain amount of literature survey
or on site study if the information is not well known. Two
steps  are particularly important:

  1.  identification  of the important  species  and  com-
munity (primary production, species diversity, etc.) that are
relevant to this site;  and
  2.  determination of life patterns of the important species
(seasonal distribution, migrations, spawning areas, nursery
and rearing areas, sites  of commercial or sport  fisheries).
This information should  include as much specific informa-
tion on thermal requirements as it is possible to obtain
from the literature.

  Other steps  relate the life  patterns and  environmental
requirements of the biota to the sources of potential thermal
damage from the power plant. These steps can be identified
with specific areas in Figure III—7.

Aquatic Areas Sensitive to Temperature Change

  Five principal areas offer potential for biological damage
from thermal changes, labeled A-E on Figure III-7. (There
are other   areas associated with  mechanical  or chemical
effects that cannot be treated here; see the index.)

  Area A  The cooling water as it passes through the intake,
          intake piping (Ai),  condensers, discharge piping
          (A2) or canal  (A'2), and thermal plume (A3 or
          A's), carrying  with it small organisms  (such as
          phytoplankton, zooplankton, invertebrate larvae,
          and fish  eggs  or larvae). Organisms receive a
          thermal shock  to the  full  20 F above  ambient
          temperature with a duration that depends upon
          the rate of water flow and the temperature drop
          in the plume.
  Area B Water  of the plume alone that entrains  both
          small and larger organisms  (including small fish)
          as it is diluted (B  or  B'). Organisms  receive
          thermal shocks from temperatures ranging from
          the discharge to the  ambient temperature, de-
          pending upon where  they are entrained.
  Area G Benthic environment where bottom organisms
          (including fish eggs) can be heated chronically or
          periodically  by the thermal  plurne (C or G').
  Area D The slightly  warmed mixed water body (or large
          segment of it) where all organisms experience a
          slightly warmer average temperature (D).
  Area E The discharge canal in which resident or seasonal
          populations  reside at abnormally high  tempera-
          tures (E).

Cooling Water Entrainment
  It is not adequate to consider only  thermal criteria for
water bodies alone when large numbers of aquatic organisms
may be pumped  through a power plant. The probability
of an organism being  pumped through will depend upon
the ratio of the volume of cooling water in the plant to the
volume in the lake (or  to the volume passing the plant in a
river  or tidal fresh  water).  Tidal  environments  (both
freshwater and saline)  offer greater potential for entrain-
ment than is apparent, since  the same water mass will
move back and forth past the plant many times during the
lifetime  of  pelagic  residence  time  of  most  organisms.
Thermal shocks that could be experienced by organisms
entrained at  the hypothetical  power station are shown in
Figure III-8.
  Detrimental effects of thermal exposures received  during
entrainment can be judged by using the following  equation
for short-term exposures to extreme temperatures:
           General criterion: 1>
                                    time
Values for a and b in the equation for the species of aquatic
organisms that are likely to be pumped with cooling water
may be obtained from  Appendix II, or  the data may be
obtained using the methods of Brett (1952).252 The prevailing
intake  temperature  would  determine  the  acclimation
temperature to  be selected from the table.
  For example, juvenile largemouth bass may  frequent the
near-shore waters of this lake and be drawn into the intake.
To determine whether the hypothetical thermal discharges
(Figure III-7) would be detrimental for juvenile bass, the
following analysis can  be made (assuming, for example,
that the lake is in Wisconsin where these basic data for bass
are available):

Travel time in piping to discharge is  assumed to be
1 min.,  and temperature drop to below the lethal
threshold minus 2 C (29.5 C or$5.1 F)  is about 10 sec.
(Pritchard, 1971).312

Conclusion

  Juvenile bass would survive this thermal exposure:

                   1>0.1630

  By using the equation in the following form,

          log (time)=a+6 (temp.+ 2)

the length of time  that bass could barely survive  the
expected temperature rise could be calculated, thus
allowing selection of an appropriate discharge system.
For example:

      log (time) =34.3649-0.9789 (34.22)
      log (time) =0.8669
          time =7.36

 170/Section III—Freshwater Aquatic Life and Wildlife
       This would be about 1,325 feet of canal flowing at
     3 ft/sec.

   It is apparent that a long discharge canal, a nonrecircu-
lating cooling pond,  a very long offshore cioe, or delayed
dilution in a mixing zone (such as the one promoting surface
cooling) could prolong the duration of exposure of pumped
organisms and thereby increase the likelihood of damage to
them. Precise information on the travel times of the cooling
water in  the discharge system  is needed to conduct this
analysis.
   The calculations have ignored changing temperatures in
the thermal plume, because the canal alone was lethal, and
cooling in the plume with rapid dilution was so rapid that
the additional exposure was only for 10 seconds (assumed to
be at the discharge  temperature the whole time).  There
may  be  other circumstances under which the  effect  of
decreasing  exposure  temperature  in  the plume  may  be
of interest.
   Effects  of changing temperatures in the plume can  be
estimated by summing the effects of incremental exposures
for short time periods  (Fry et al. 1946281).  For example, the
surface cooling plume of Figures  III-7  and III-8  could  be
considered to be composed of several short time spans, each
with  an average temperature, until  the  temperature had
dropped to the upper lethal  threshold minus  2 G for the
juvenile bass. Each time  period would be calculated  as if
it were a  single exposure, and the calculated values for  all
time  periods would be summed and compared with unity,
as follows:
       timei
time,,
  }Q[a+b(temp.i+2)]
                     [a+b(temp .
  The surface cooling plume of Figure III-6 (exclusive of
the canal) could  be considered to consist  of  15  min  at
89.7 F (32.06C),  15 min  at  89.2 F (31.78 C),  15  min  at
88.7 F (31.4 C),  15 min  at  88.2 F  (31.22C), 15  min  at
87.8 F (31.00 C), until the lethal threshold for 70 F acclima-
tion minus 2 C (85.1 F) was reached. The calculation would
proceed as follows:
1 >
              15
     1Q [34.3649— 0.9789(32.06+2)]
                                     15
                               4.364 9— 0.9789(31.78+2)]
  In this case, the bass would not survive through the first
15-minute period. In other such calculations, several steps
would have to be summed before unity was reached (if not
reached, the plume would not be detrimental).

Entrainment in the Plume
  Organisms mixed with the thermal plume during dilution
will also receive thermal shocks,  although the maximum
temperatures  will generally be less  than the  discharge
 temperature. The number of organisms affected  to  some
 degree  may be  significantly greater than  the numbers
 actually pumped through the plant. The route of maximum
 thermal exposure for  each  plume is indicated in Figure
 III-7 by  a  dashed line.  This route should be analyzed to
 determine the maximum reproducible effect.
   Detrimental effects of these exposures can also be judged
 by using the criterion for short-term  exposures to  extreme
 temperatures. The analytical steps were outlined above for
 estimating the effects on organisms that pass through the
 thermal plume portions of the entrainment thermal pattern.
 There would have been no mortalities of the largemouth
 bass from entrainment in the plume with rapid dilution, due
 to the short duration of exposure (about 10 seconds). Any
 bass that  were entrained in the  near-shore portions of the
 larger plume, and remained  in it, would have died in less
 than 15 minutes.

 Bottom Organisms Impacted by the Plume
   Bottom communities  of  invertebrates, algae,  rooted
 aquatic plants,  and  many  incubating fish  eggs  can be
 exposed to  warm  plume water,  particularly  in  shallow
 environments. In some circumstances the warming can be
 continuous,  in others it can be intermittent due to  changes
 in plume configuration with changes in currents, winds, or
 other factors. Clearly a thermal plume that  stratifies and
 occupies only the upper part of the water column will  have
 least effect on bottom biota.
   Several approaches are useful in evaluating effects on the
 community. Some have predictive capability, while others
 are suitable largely for identifying effects after they  have
 occurred.  The criterion for short-term exposures identified
 relatively  brief periods of detrimental high temperatures.
 Instead of the organism passing  through zones of elevated
 temperatures, as in the previous examples, the organism is
 sedentary, and the thermal pulse passes over it. Developing
 fish eggs may be very sensitive to such changes.  A  brief
 pulse of high temperature that kills large numbers  of orga-
 nisms may affect a bottom area for time periods far longer
 than the immediate exposure time. Repeated sublethal ex-
 posures may also  be  detrimental, although the process is
 more complex than straight-forward  summation. Analysis
 of single exposures proceeds  exactly as described for plume
 entrainment.
   The criterion  for prolonged exposures is more generally
 applicable. The  maximum tolerable weekly  average  tem-
 perature may be determined  by  the organisms present and
 the phase of their life cycle. In  May, for  example, the
 maximum heat  tolerance temperature for the community
may be determined by incubating fish  eggs or fish fry on the
 bottom. In July  it may  be  determined by the  important
resident invertebrate species. A well-designed thermal dis-
charge should not require an extensive mixing zone where
these criteria are exempted. Special criteria for reproductive
processes may have  to be applied, although thermal dis-
                                                      47

charges  should be located so  that zones  important  for
reproduction—migration, spawning, incubation—are not
used.
  Criteria for species  diversity provide  a useful tool  for
identifying  effects of  thermal  changes  after  they  have
occurred, particularly the effects of subtle changes that are
a result of community interactions rather than physiological
responses by one  or  more major species. Further research
may  identify critical temperatures  or sequences of tem-
perature changes that cannot be exceeded and may thereby
provide  a predictive capability as well.  (See Appendix
II-B.)

Mixed Water Body (or major region thereof)
  This  is the region  most commonly considered in  es-
tablishing water quality standards, for it generally includes
the major area of the water body. Here the results of thermal
additions are observed as small temperature increases over a
large area (instead of high temperatures locally at the dis-
charge point), and all heat sources become integrated into
the normal annual temperature cycle (Figure  111-6 and
Figure III-7 insert).
  Detrimental high temperatures in this area (or parts  of
it)  are defined by the  criteria for maximum temperatures
for prolonged  exposure  (warm  and cool  months) for the
most sensitive species or  life stage occurring there, at each
time of year, and  by  the  criteria for reproduction.
  For example,  in the lake with the  hypothetical power
station, there may be 40 principal fish species, of which half
are  considered important.  These species  have  spawning
temperatures  ranging from  5 to 6 C for the  sauger (Stizo-
stedion canadense) to 26.7 C for the spotted bullhead  (Ictalurus
serracanthus}. They also have a similar range of temperatures
required  for  egg  incubation, and  a  range  of maximum
temperatures  for  prolonged  exposures  of juveniles and
adults. The requirements, however,  may be met any time
within normal time spans, such as January 1 to 24 for sauger
spawning, and March  25 to April 29 for smallmouth bass
spawning. Maximum temperatures for prolonged exposures
may increase steadily throughout  a  spring period.  To
predict effects of thermal discharges the pertinent tempera-
tures for reproductive activities and maximum temperatures
for each life stage can be plotted over a 12-month period
such as shown in Fig. III-6. A maximum annual tempera-
ture curve can become apparent when sufficient biological
data are available. Mount (1970)305 gives  an example of
this type of analysis.

condenser cooling water can develop biological communities
that are atypical of normal seasonal communities. Interest
in these areas  does not generally derive from concern for a
balanced ecosystem, but rather from effects that the altered
communities can have on the entire aquatic  ecosystem.
   The  general  criteria  for nuisance  organisms may  be
applicable.  In the discharge canals of some existing power
stations, extensive mats of temperature-tolerant blue-green
algae grow and periodically break away, adding a decom-
posing organic matter to the nearby shorelines.
   The  winter criterion  for  maximum temperatures for
prolonged exposures identifies the potential for fish kills due
to  rapid decreases in temperature. During  cold seasons
particularly,  fish are  attracted  to warmer water of  an
enclosed area, such as a  discharge canal. Large numbers
may reside there for sufficiently long periods  to  become
metabolically  acclimated  to  the  warm  water.  For any
acclimation  temperature there is a minimum temperature
to which the species can be cooled rapidly and still survive
(lower  incipient lethal  temperature).  These  numerical
combinations,  where  data are  available,  are  found  in
Appendix II-C.  There would be 50 per cent mortality, for
example, if largemouth  bass  acclimated in a  discharge
canal to 20 C, were cooled to 5.5 C  or below.  If normal
winter  ambient  temperature  is less  than 5.5 C,  then the
winter  maximum should be  below  20 C,  perhaps nearer
15 C. If it is difficult to maintain the  lower temperatures,
fish should be  excluded from the area.

 16. ABSTRACT
       The evolution  of  freshwater temperature criteria  is discussed  as it
 rcilates to standards  development by  regulatory agencies.  The present,
 generally accepted  philosophical approach to criteria  development  is explained
 in detail and its use  to protect various life stages of fish is  demonstrated
 by selected examples.   Numerical criteria for survival, spawning,  embryo
 development, growth,  and gamete maturation of fish  species were  calculated
 and tabulated.
