 Introduction
This report is a fifteen-year summary of
information contained in federal fish kill
publications,  based on voluntary
reporting by State and local agencies.
The report includes: An analysis of data
which describes the number of incidents,
the total number of fish killed, the
average size of a kill, and the largest fish
kill or kills reported. The report also
includes the number of reported
incidents by each pollution source
operation and by the individual sources
of pollution under these major
operations.

It should be stressed that pollution-
caused fish kills reported in this
publication probably represent only a
fraction of the kills  which actually
occurred during the 1961-1975 period,
partly because the  reporting offish kills
is voluntary. Also, numerous small kills
often go unnoticed or unreported, and
significantly large kills are  often not
included due  to lack of sufficient
information to determine if the kills were
caused by pollutants, or were due to
natural causes. It is often quite difficult to
determine the actual cause of a kill, even
using the most careful investigative and
analytical procedures.

The Public Health Service began
reporting pollution-caused fish kills on
June 1, 1960, under the authority of the
Federal Water Pollution Control Act, PL
84-660, Section 4(C). In 1960, the
Surgeon General of the Public Health
Service requested that all State fish and
game conservation agencies report
instances of fish kills attributable to
pollutants. Working closely with the U.S.
Fish  and Wildlife Service and various
independent conservation  organizations,
the Public Health Service designed a  self-
addressed postcard reporting form
(Appendix B). This  form was furnished to
the State agencies to be completed when
fish kills occurred. Summary totals,
statistical evaluations, and conclusions
were, and continue to be, based upon the
information contained in these reporting
forms.
In 1972, the responsibility for fish kill
reporting was transferred to the United
States Environmental Protection Agency
(EPA) in an attempt to secure additional
information on the effects of pollutants
discharged to surface waters. The
principal objective was to determine, if
possible, the causes of fish kills, and to
place responsibility when kills were
caused by man-made pollution.

-------
  Foreword
  The annual EPA fish kill reports represent
  the combined voluntary efforts of private
  individuals. State fish and game, health,
  and conservation officers, and water
  pollution control officials at the State and
  Federal level. Usually, a fish kill is first
  noticed by a fisherman, camper, or other
  private citizen who initiates the reporting
  process by contacting a warden or other
  State official. The State agency then
  sends trained specialists to investigate
  and identify the species, the cause, and
  size of the kill. Where water pollution is
  determined or suspected to be the cause,
  the State submits a report to the EPA.

  The reporting system depends, to a large
  extent, upon individuals in the field
  making State officials aware of fish kills.
  It is quite likely that the large increases in
  reports since 1970 over earlier years are
 at least partially a result of increased
 public awareness of pollution. In an effort
 to further increase this awareness and to
 encourage individuals to report kills to
 State officials, we are including
 Appendixes A, B, and C to this report:

 • Appendix A—A list of State agencies
who should be notified of kills;

 • Appendix B—A reproduction of the
report form to show the information
desired; and

• Appendix C—A definition of the
types of operations identified as
pollutant sources.

-------
Statistical  Highlights
The following are summary statistics of
fish kills reported from 1961 through
1975.

   • A total of 465.4 million fish were
   reported killed by pollution during the
   1961-1975 period.

   • Municipal operations accounted for
   195.3 million fish killed (42 percent)
   and led all other sources of pollution.
   Industrial operations was second,
   accounting for 98.5 million fish killed
   (21 percent). The remaining fish kills
   (38 percent) were divided among
   agricultural, transportation, and other
   operations.

   • Industrial operations, with 2,845
   incidents (32 percent), led all other
   sources of pollution in reported fish kill
   incidents.

   • A total of 8,967 fish kill incidents
   were reported during the 1961-1975
   period. The greatest annual number of
   incidents (860) were reported in 1971.

   • A total of 79 reported incidents
   involving a million or more fish
   accounted for 360.1 million dead fish
   or 77.4 percent of all fish killed.

   • Florida led all States in the number
   of reported incidents involving a
   million or more fish killed (15
   incidents), followed by Texas (14
   incidents).

   • Sewerage systems led all individual
   sources of pollution in the number of
   fish kill incidents involving 1,000,000 or
   more fish (133,000,000 fish—23
   reported incidents).

   • Ohio led all States in the total
   number of reported incidents (1,011),
   followed by Pennsylvania (983).

   • A total of 7,253 fish kill incidents (82
   percent) were reported on rivers, 1,424
   incidents (15 percent) were reported on
   lakes, and 290 incidents (3 percent)
   were reported in coastal waters.

   • Maryland led all  States in the
   number of fish reported killed (104
   million, or 22 percent).
• A total of 47 million fish were
reported killed in the largest single
reported incident. This major fish kill
occurred in the Back River near Essex,
Maryland in 1974.

• A total of 335 million fish (72
percent) were reported killed during
the summer months of July, August,
and September.

• Of the 430 million fish reported
killed during the 1961-1975 period, 90
percent were classified as non-game
fish.

• Low dissolved oxygen was identified
as the leading  cause of fish kills during
the 1961-1975 period, accounting  for
21 percent of the reported fish kill
incidents.

• Pesticides led all  other specific
causes in reported incidents (18
percent).

• A comparison of  regional variations
of fish kill incidents  for the most recent
five-year period, 1971-1975, shows that
of the 10 EPA regions. Region V (Ohio,
Indiana, Michigan, Illinois, Wisconsin,
and Minnesota) had the highest
percentage of  incidents (21 percent),
followed by Region  IV (Alabama,
Florida, Georgia, Kentucky, Mississippi,
North Carolina, South Carolina, and
Mississippi) with 18 percent.

-------
  Basic Statistics
  In 1961, the first full year of the voluntary
  fish kill reporting program, 45   .
  participating States reported 413
  incidents. During that year, a small
  number of incidents (9) were identified as
  major fish kills (100,000 or more fish),
  accounting for 90 percent of the total
  reported fish killed. Major kills continued
  to account for the greatest number of
  fish killed between  1961 and 1975.

  The number of States participating in the
  fish kill reporting program dropped to 37
  and 38 in 1962 and  1963, respectively. It
  is suspected that this decreased State
  activity was due to  unobserved or
  unreported kills, rather than to decreased
  water pollution. Between 1964 and 1971,
  however, the number of participating
  States increased, ranging from 40 to 46
  States.

  In 1972, all 50 States participated in the
  reporting program for the first time.
 However, six States reported that there
 were no recorded pollution-caused fish
 kill incidents that year.

 Between 1961 and 1975,8,967 reports
 were submitted involving 465.4 million
 dead fish (Table 1). Sources of pollution
 were identified in 84 percent (7,498) of
 the reports submitted. The annual
 estimated number of fish killed ranged
 from a low of 6.9 million in 1963 to a
 record high of 119 million in 1974 (Figure
 1).

 It is essential that a fish kill be reported
 and  investigated immediately in order to
 determine the source of pollution and the
 polluting agent. Dead fish may be
 washed downstream from the source of
 pollution. The polluting agent may be
 diluted by fast-flowing water, making on-
 site investigation difficult or even
 impossible. Hot weather conditions
decompose fish tissue, also making it
difficult to identify a  polluting agent.
 Since the investigator can count or
 estimate only those fish which lie on or
 near the surface, the number of fish
 reported killed is almost always a
 conservative figure. In some cases, as
 much as 80 percent of the dead fish
 cannot be counted due to turbid water,
 or because the fish have either sunk to
 the bottom of the water body or have
 been washed away from the site of the
 kill.

 During the 15-year period, industrial
 operations—the leading source of
 reported incidents—accounted for 32
 percent of all reported incidents.
 Incidents reported under industrial
operations ranged from a low of 20
percent in 1975 to a high of 50 percent in
1962. Industrial operations ranked first in
the number of reported incidents for 14
of the 15 years (Figure 2).

-------
Basic Statistics
Agricultural and municipal operations
were the next most common causes of
fish kills, with each accounting for 18
percent of the reported incidents.

Transportation operations accounted for
5 percent of the reported incidents over
the fifteen-year period, while other
operations accounted for 8 percent of the
incidents. In  19 percent of the incidents,
the cause of the kill was not  known.

In 1974, 47 million fish were killed in one
incident in Back River, near Essex,
Maryland eclipsing the previous high for
one incident which was 37.8 million
reported in a single kill in 1962 near San
Diego Harbor, California. Three other
1974  incidents in Back River  caused kills
of 31.9, 11.0, and 10.7 million fish. More
fish were reported killed in each of these
incidents than  in any other single
incident with one exception: An incident
in Lake Thonotossassa, Florida in 1969 in
which 26.5 million fish were killed.

Although kills of over 1,000,000 fish
accounted for only one percent of the
incidents, these incidents accounted for
77 percent of the fish reported killed
during the 15-year period (Table 2). The
largest percentage of the reports
submitted (39 percent) were within the 0
to 1,000 range offish killed.  This range
had the lowest percentage of fish
reported killed (0.2 percent).

                                           1961 and 1975.
 Industrial Operations had the highest
 percentage of reported fish kill incidents (32
 percent) during the 15-year reporting period
 (Figure 2).

-------
  Basic Statistics
  Total Fish Reported Killed
  A total of 465.4 million fish were reported
  killed (Figure 3) in 7,492 separate
  incidents of water pollution from all
  sources (Table 3, Figure 4). During the
  fifteen-year period (1961-1975) the
  largest number offish kills reported in
  the United States were classified as
  municipal operations (42 percent), with
  sewerage systems being the major
  municipal operation causing fish kills
  (Figure 5). Industrial operations ranked
  Second (21 percent) in the number of
  reported fish kills; unknown causes
  ranked third (18 percent), other
  operations ranked fourth (12 percent),
  agricultural operations ranked fifth (6
  percent) and transportation operations
  ranked sixth and last with one percent. In
  the remaining 1,475  reports (1& percent),
  fish losses were either not stated, or
  were not expressed in numerical terms.

  Of the 465.4 million fish killed (Table 4),
  422.7 million (90 percent) were classified
  as non-game fish* and 10 percent were
  classified as game fish.

                                 Over 465 million fish were reported killed by
                                 pollution during the 15-year period. Figure 3
                                 summarizes the reported number of fish killed
                                 for the 1961-1975 period. The first reporting
                                 year, 1960 was excluded since reports were
                                 not received for the full year.

   Source of Pollution
Municipal operations killed more fish (195
million) than any other operational source of
pollution (Figure 4).
Table 3 Summarizes fish kills by major and
individual sources of pollution. Municipal
operations was the leading source of
pollution, accounting for 42 percent of the fish
reported killed.

  Basic Statistics
  Water Quality Changes
  Associated with Fish Kill
  Incidents
 The operations previously described lead
 to specific changes in the water
 conditions which cause the fish kills.
 These specific causes were identified for
 8,967 kills over the 15-year period.

 Low dissolved oxygen (Table 5, Figure
 6) was the leading known specific cause
 offish kills, resulting in 1,893 incidents
 (21 percent). Pesticides ranked second as
 a known cause of reported fish kills (18
 percent), while petroleum and inorganic
 chemicals ranked third (8 percent). Acids
 and organic chemicals ranked fourth (5
 percent each), followed by fertilizers and
 mixed chemicals (2 percent each), and
 thermal and combinations (1 percent
 each). The specific cause was not known
 for 29 percent of all reported fish kill
 incidents.
 Low dissolved oxygen was the leading specific
 cause of reported fish kills (21 percent. Figure
 6).

 Table 5 summarizes fish kill reports by
 individual sources of pollution and specific
 causes during the 15-year reporting period.

Basic Statistics
Major Fish Kills
Between 1961 and 1975, a total of 425
million fish were reported killed in 333
incidents which involved more than
100,000 fish killed in each incident (Table
6). Industrial operations accounted for
the greatest number of incidents (105
reports or 32 percent), while municipal
operations accounted for the greatest
number of fish killed (187 million or 43
percent). Sewerage systems led all
individual sources of pollution in the
number of major fish  kill reports (82
reports or 24.6 percent), and in the
number and percent of fish killed (166
million, 39 percent).
Seventy-seven of these  major incidents
involved a million or more fish each and
accounted for a total of 382 million dead
fish within 21 States and the District of
Columbia (Table 7). The States of
Alabama, Florida, and Texas (Figure 7)
reported the largest number of individual
fish kills of one million or more fish.
Alabama submitted nine of these reports
totaling 15 million fish, with sewerage
systems causing six incidents involving
12 million fish. Four of these large kills,
totaling 7,000,000 fish, occurred near
Mobile, Alabama.

                                          occurring between 196 J and 1975 in which
                                          100,000 or more fish were killed in each
                                          incident. Industrial operations accounted for
                                          the greatest number of incidents (105 reports
                                          or 31.5 percent), while municipal operations
                                          accounted for the greatest number of fish
                                          killed (187 million fish, or 43 percent).

 Basic Statistics
  Fish Kills, by Type of Water
  Body
  Of the 8,967 fish kill incidents between
  1961 and 1975 (Table 8), 7,253 (81
  percent) occurred in rivers, 1,424 (16
  percent) occurred in lakes, and 290 (3
  percent) occurred in coastal waters
  (Figure 8).
A total of 213.5 million fish were killed  ,
in rivers, accounting for 46 percent of the
fish reported killed between 1961 and
1975 (Figure 9). Fish killed in lakes (61
million) accounted for 13 percent offish
reported killed, and the fish killed in
coastal waters (190.8 million) accounted
for 41 percent of the fish reported killed
during the 15-year summary period.
Therefore, the kills in coastal waters
were, on the average, much larger than
the kills in rivers and streams.

Ohio led in the number of incidents
reported in rivers (985), Florida led in the
number of incidents reported on lakes
(130), and California led in the number of
incidents (91) reported in coastal waters
(Figure 10).

 Table 8 summarizes data from the 50 States
 which reported one or more pollution-caused
 fish kill incidents. Of the 8,967 reports
 submitted, 7,492 indicated the number of fish
 killed. The remaining  1,475 reports did not
 specify the number of fish killed. The table
 also shows the number of reports for incidents
 that occurred in rivers, lakes, and coastal
 waters and the areas affected.
                                               Ohio reported the largest number of fish kill
                                               incidents occurring in rivers (985 reports)
                                               while Florida (Figure 10) reported the largest
                                               number of incidents occurring in lakes (130
                                               reports). California led all other States in the
                                               number of incidents occurring in coastal
                                               waters (91 reports).

 Basic Statistics
  Fish Kills, by Month
 The greatest number of reports (5,375 or
 60 percent of the total number of reports)
 were submitted for the warm weather
 months of June, July, August, and
 September (Table 9). In terms of fish
 killed, August ranked first with 195
 million, or 42 percent of all fish killed
 during the 1961-1975 period, followed by
 July and September with approximately
 70 million fish (15 percent)  each. The
 smallest number of fish were killed in
 February and December (two and three
 million, respectively).

 Five-Year Summary of  Fish Kill  Reports,
 by Sources  of Pollution  in Ten EPA
 Regions,  1971-1975
Table 10 summarizes the fish kill
incidents by pollution source operations
within each Environmental Protection
Agency Region for the 1971-1975 period.
Figure 11 is a national map that outlines
the EPA regional boundaries and the
States and territories that make up each
region.

The variations  between EPA regions
reflect the characteristics of the regions.
For example, industrial operations, led by
the chemical, petroleum and mining
industries were by far the major cause of
fish  kills in Region III, which includes the
heavily industralized areas along the
lower Delaware River and near
Pittsburgh, as well as the Appalachian
coal mining areas in Maryland,
Pennsylvania, and West Virginia. On the
other hand, agricultural operations were
the major cause of fish kills  in Regions
VII and VIII, which include much of the
nation's farm belt.

Appendices
Introduction
Appendix A lists the State agencies
actively participating in the fish kill
reporting program. Observers are
encouraged to report any sightings of
dead fish to their appropriate State
agency. Since, if the cause is not readily
apparent, time is important to an
investigation, reports should be
submitted as soon as possible, preferably
by telephone to the local offices of the
agency (game wardens, for example). If
no local office is present,  reports can be
mailed to the  agency at the addresses
shown.

Appendix B is a  reproduction of the
report form showing information desired.
It is recognized that the casual observer
cannot normally provide much of the
information; however, location, estimates
of the number of dead fish and tissue
and date of the observation are
extremely important. Also important is
the probable source of pollution where it
can be identified.

Appendix C defines pollution sources in
terms of the type of operation involved.
Since the number of dead fish may not
be indicative of the severity of the
pollution, proper State officials should be
notified even  when only a small number
of dead fish are seen floating on a water
body. In cases where the  fish kill was due
to causes other than man-created
pollution, State officials are still
interested in determining the cause, and
should be nofified.
                                                                          73

Appendix C
Glossary

Sources of Pollution by Type of Operation

Fish kills may be caused by pollution
from a large number and variety of
sources. To facilitate reporting of kills,
these pollution sources have been
categorized according to the types of
operations (municipal, industrial, etc.)
producing the pollution. Following are
definitions of each operation to include
breakdowns into subcategories.
Agricultural Operations

Pollution from agricultural operations
results primarily from wastewater runoff
from fields where various chemical
compounds are used for pest control and
fertilizers. Runoff from feedlot operations
are also included under this category. In
addition, a probable cause of pollution
lies in the handling of various pesticides
or fertilizers, the cleaning of equipment
used to disperse these chemicals, and
the handling and disposal of the
containers.

•  Poisons (Pesticides, Etc.)
Poisons include any of the "cides" used
at the site of agricultural operations,
which may be introduced into a water
body through a runoff after a rain or
through settling from the air.

•  Fertilizers
This subcategory applies to commercial
fertilizers after they have been delivered
for use.

•  Manure Drainage, Ensilage Liquors, or
Feed Lot Operations
In addition to the operations  named in
this heading, this subcategory includes
other agricultural operations which may
be a source of pollution through poor
housekeeping practices.

•  Handling of Equipment and Containers
This subcategory includes washing of
equipment, handling and storage of
pesticide or fertilizer compounds before
use, and container disposal.
                                         Construction, or Other

                                         • Construction operations such as the
                                         building of highways, dams, industrial
                                         complexes and other structures in or
                                         near waterways, are a frequent source of
                                         pollution.

                                         The following are examples of the
                                         "other" category.

                                         • Large residential or custodial facilities
                                         not connected to municipal sewers but
                                         having their own system, for example,
                                         Federal, State, and church institutions,
                                         custodial institutions such as old folks
                                         homes, universities, etc.

                                         • Domestic service operations in
                                         suburban or rural areas resulting in direct
                                         discharges such as spent drycleaning
                                         solutions and wash and rinse water from
                                         coin laundries and dry cleaners, and
                                         spent floor and paint cleaners.
• Highway restaurants, motels, resort
areas, and auto service areas which may
or may not have their own treatment
plant.
Industrial Operations

Industrial operations involve
manufacturing or processing industrial
and commercial products.

• Mining
Pollution from mining operations is most
often caused by acid mine drainage from
coal mines. In addition, coal washings
and taconite tailing disposal are included
here as well as side products from all
other mining operations, including
mining for ore, limestone, phosphate,
etc.

• Chemicals
This subcategory includes manufacture
of the following:
Basic chemicals such as acids, alkalies,
salts, and organic chemicals;
Chemical products to be used in further
manufacture such as synthetic fibers,
plastic materials, dry colors, and
pigments; and,
Finished chemical products for ultimate
consumption  (cosmetics, drugs and
soaps); or to be used as materials or
supplies in other industries (paints,
fertilizers, and explosives).

• Food and Kindred Products
These operations include those involved
in preparing and processing fresh and
raw food items and other related
products for the market. Examples
include:
Sugar refining;
Canning, dehydrating, freezing, or curing
of fruits, vegetables, or fish and other
seafood;
Grain processing into flour, cereal
products, etc.;
Slaughtering or meat packing;
Dressing poultry;
Any milk-handling operation including
dairy farm, cheese factory, condensery,
creamery, or ice cream  plant-
Breweries, wineries, or  distilleries
operations;
Rendering plants or vegetable oil
manufacture; and.
Animal feed manufacture.

• Textiles
Textile production covers all  milltype
operations, including bleaching and
dyeing processes.
                                                                                                                       77

-------
 •  Metals
 This subcategory includes all operations
 involving metals and plating (except
 mining), such as blast furnaces, smelting,
 rolling mills, pickling, heat treatment, etc.
 Common sources of wastes are metal
 cleaning solutions and plating vats which
 contain large amounts of acid, cyanide,
 copper, iron, chrome, and arsenic, all of
 which are specific causes offish kills.
 In addition, coke ovens and inefficient
 clarifier tanks in steel mills add toxic
 chemicals and turbidity to waste water.

 •  Petroleum
 Petroleum covers oil or gas well drilling,
 oil refining, and the manufacture of any
 petroleum products.

 •  Paper and Allied Products
 Paper and allied products covers paper-
 making in any of its stages, including
 resultant sludge deposits in streams or
 lakes.

 •  Rubber and Plastics
 This subcategory includes manufacture
 from natural, synthetic, or reclaimed
 rubber. It also includes manufacturing
 involved in molding primary plastics for
 trade, and miscellaneous finished plastic
 products.

 •  Other Industrial
 "Other" applies to those industries not
 specifically designated. The following are
 examples of potential entries under this
 item.
Lumber and wood products production
including logging, chemical treatment,
and sawmill operations through the
finished product;
 Leather and leather products processing
and production;
Sand and gravel washing; and.
Automobile manufacturing.
Municipal Operations

Municipal operations are those activities
that are the responsibility of the
municipality in providing public utilities
and other services.
• Sewerage System
Includes municipal sanitary and storm
sewers and combined sewers. The
wastes may be treated or untreated
before they enter or leave the municipal
system.

• Refuse Disposal
Refuse disposal concerns dumps, land fill
projects, etc., used for disposal of solid
wastes. The prime cause of fish kills from
these sources is drainage from these
areas, and deposits of ash from
incinerators into surface water bodies.

• Water System
Fish kills charged to water system
include kills caused by excessive use of
chemicals for pipe cleaning and for
algae, weed, and insect control in
reservoirs. A common source of kills
from this source is high chlorine
solutions drained  from new pipe lines,
storage tanks, reservoirs, and pump
stations, which are used to sterilize new
water supply facilities.

• Swimming Pools
Fish kills charged  to swimming pool
operations generally result from cleaning
operations or use of excessive chlorine.
This subcategory  applies if pool drainage
is not connected to the city sewer
system, regardless of who owns or
operates the pool.

• Power (Public Service)
Power generation considered here is the
production of power intended for
consumption by the general  public,
versus power generation necessary to
operate a manufacturing  plant. Thermal
pollution is of prime concern, although
wastewaters such as that from boiler
blowdown  sometimes cause fish kills,
most often during low flows.

• Pest Control
This subcategory  of operations includes
spraying of ponds, creeks, marshes, or
use of other various methods of insect
control when the poisons used are
deposited directly into a waterway, as
opposed to being conveyed to the
waterway via a municipal sewer system.
Transportation Operations

The major source of pollution from these
operations is accidental spillage into
waterways of products in transit
regardless of source, destination, or
ultimate use.

•  Rail
Fish kills charged to this subcategory are
caused by accidental product spills,
whether due to a wreck or by handling in
yards. Waste discharge from railyard
operations also applies here.

•  Pipeline
Pipeline means those lines used to
transport liquids or gases for long
distances.

•  Truck
A fish kill charged to this subcategory
most  often results from a wreck, leakage,
or careless handling in transit and at
terminals.

•  Air
This subcategory includes operation of
airports, which are frequent producers of
oily wastes and highly alkaline aircraft
washrack drainage, as well as aircraft
operations. It also includes aircraft
crashes which should be considered in
the same light as accidents involving
trains, trucks, boats, etc.

•  Barge or Boat
Barge or boat operations may result in
pollution through spillage of products
resulting from bilge discharges, fire,
collision, sinking, or mishandling the
products while in transit. Transit, in this
case,  includes transfer to or from the
vessel while docked.
Unknown

The unknown category is applied to a
fish kill when the pollution source
operation cannot be determined or
surmised, and the investigator is
reasonably sure that the kill was due to
pollution.
