2.1.7.  AQUATIC ECOLOGY

2.1.7.1.  GENERAL OVERVIEW

A.  Historical Background

     Any retrospective characterization of the aquatic ecology of the Pennsyl-
vania ORBES region to colonial times must rely heavily upon scattered histor-
ical documents that make reference to fish fauna.  A review of such documents
has led Lachner (1) to conclude that "...the fish heritage in the Upper Ohio
Basin was extremely rich.  Dense schools of fish existed in these waters.
Early explorers and pioneers traversing the Alleghenies found the streams
teeming with life and these provided them with a ready source of excellent
food."  The seventeen species listed by Lachner (Table 2.1.7.-1), although
not all suitable as table fare, were reported as occurring in the Upper Ohio
Basin prior to 1900.  Many of these species probably never were exceedingly
numerous in the basin.  Others were reported as being common to abundant in
colonial times.  About one-third of these seventeen species still inhabit
that portion of the basin in Pennsylvania.  Nonetheless, Lachner notes of
this list that "...the general data warrant the thesis that there has been a
great reduction in numbers and the extirpation of many forms."  Indeed, many
of the species currently categorized by the Pennsylvania Fish Commission as
"endangered," "threatened," or "status indeterminate" (see Table 2.T.7.-2)
were once inhabitants of the Ohio River Basin.  Habitat preferences for most
basin fishes are outlined in Appendix A.

B.  Past Impacts

     Relatively little eighteen and nineteenth century information exists that
would help characterize the plankton, periphyton, and macrobenthos of western
Pennsylvania waterways.  It has been reported (4, 5) that several mussel beds
containing various species occurred in the Allegheny, Monongahela, and Ohio
Rivers in 1805.  However, such interesting tidbits of historical information
are too scarce to provide a complete description of past conditions.  A more
broadly based historical characterization can be arrived at by considering
the probable ecological impacts of channelization, the first major man-induced
alteration of the river system.  Prior to the construction of locks and dams,
the "Three Rivers" consisted of alternating reaches of sluggish, deep pools
and extremely shallow riffles (see Section 2.1.5.-Surface Hydrology).  It can
be hypothesized that the aquatic biota of that time was essentially composed
of species typical of free-flowing, temperate zone rivers.  Conversely, due
to the present navigation system, the Ohio, Monongahela, and lower Allegheny
Rivers ecologically behave much as a series of narrow connected impoundments.
The navigable rivers are currently inhabited by lentic (lake-like) biota;
moreover, they are essentially devoid of forms adapted exclusively to riffles.
The following trends are at least partially due to the consequences of lock
                                       -1-

-------
and dam construction, dredging, and snag-cleaning:

                  a.)  Increased plankton biomass
                  b.)  Increased zooplankton diversity
                  c.)  Decreased aquatic macrophyte abundance
                  d.)  Decreased benthos diversity
                  e.)  Decreased fish diversity

     Diversity decreased in benthos and fish are largely due to the fact that
the aforementioned activities create rather uniform physical conditions
throughout the rivers, thereby eliminating habitats such as riffles and shoals.

     The many categories of water pollutants in the Pennsylvania ORBES region
have further reduced the species diversity of aquatic organisms inhabiting
the major rivers.  Many pollution sensitive, lentic species which could con-
ceivably exist with the constraints of the navigation system are nonetheless
absent from the degraded reaches of the navigable rivers.  Many free-flowing
polluted tributary streams are likewise inhabited exclusively by pollution-
tolerant organisms.  The original aquatic biota of the basin were adapted to
clear streams with gravel or sand substrates (1).  However, in the late 1800's
and early 1900's intensive lumbering resulted in dramatically increased ero-
sion rates with an accompanying siltation of many streams (see Section 2.1.4.-
Terrestrial Ecology).  During the twentieth century acid mine drainage has
been the big problem, rendering receiving waters acidic and blanketing their
benthic communities with iron hydroxide precipitate (see Section 2.1.6.-Water
Quality).  Oxygen-demanding domestic wastewaters, toxic industrial wastewaters,
and thermal effluents from power plants have also contributed to past impacts
on the aquatic life of the Pennsylvania ORBES region.

     Various miscellaneous factors have also altered the ecology of western
Pennsylvania waterways.  An often overlooked factor is the introduction of
non-indigenous fish species.  Thousands of hatchery reared rainbow trout
(Salmo ga'irdneri)  (a species native to the Pacific Coast), and brown trout
(Salmo tfutta) (a species native to Europe) are released in the Pennsylvania
ORBES region every year.  Competition and predation by such stocked trout
doubtlessly alters the ecology of many small, cold water tributaries of the
major rivers.  Such streams are often stocked in numbers which are orders of
magnitude beyond their natural carrying capacity.  Moreover, preordained
times and locations for trout stocking are published events in area newspapers,
thereby producing a large crowd of fishermen which often cause additional
adverse impacts  (6).  Carp (Cyprinus carpio), goldfish (Carassius auratus),
eastern banded killifish (Fundulus d. diaphanus) and mummichog (f_. hetero-
clitus macro]epidotus) were all introduced into the basin in the pasTI  C~arp
are especially significant in that they are often the dominant fish species
in polluted reaches of western Pennsylvania waterways, out-competing native
benthophages.

C.  Present Status

     Biologists  currently responsible for assessing the water quality of west-
ern Pennsylvania's rivers are acutely aware of the paucity of detailed inform-
ation regarding  the composition, diversity, and productivity of aquatic
                                       -2-

-------
communities in the Upper Ohio River System.  Furthermore, short-term studies
which are undertaken often produce raw data that defies extensive interpreta-
tion due to the poor quality of the historical data base.  Nonetheless, one
trend seems obvious—-the major rivers of the Pennsylvania ORBES region are
currently undergoing a biotic recovery from the pollutional insults incurred
during the past century.  Only-a few technical reports (7, 8, 9), mention or
allude to this recovery.  (More extensive documentation of this phenomenon
can be witnessed in the bait shops and taverns of southwestern Pennsylvania,
where the conversation often concerns catches of warm water game fishes from
river reaches that were formerly devoid of fish or inhabited chiefly by poll-
ution-tolerant rough species.)  Indeed, as far as the general public is con-
cerned, fish species composition and abundance are perhaps the most frequently
used criteria for gauging the water quality of a river (10).  The Youghiogheny,
lower Allegheny, and upper Monongahela Rivers are good examples of recovery
areas.

     The reasons for -the return of desirable aquatic life forms to the region
are manifold.  Past mine drainage abatement projects of the Pennsylvania
Department of Environmental Resources have reclaimed a significant number of
streams.  The Federal Water Pollution Control Act Amendments (PL 92-500) have
had profound ramifications in improving the quality of municipal and industrial
effluents.  Furthermore, several Corps of Engineers reservoirs are now oper-
ated with water quality considerations incorporated into their release schedules.


2.1.7.2.  THE MONONGAHELA RIVER

A.  Phytoplankton

     Two water quality surveys of the Monongahela River were conducted by the
U.S. Army Corps of Engineers (8) in the summer of 1975.  The initial survey
was performed in June during an intermediate flow regime (5,000-12,000 cfs*)
at which time the phytoplankton concentrations of the various reaches were
found to'range between 64 and 1,439 cells/ml at a depth of one meter.  The
mean concentration at all of the sampling stations was calculated to be 515
cells/ml.   A follow-up survey initiated in July during low flow conditions
(650-1,800 cfs*) measured total  phytoplankton concentrations ranging between
31 and 6,571 cells/ml along the length of the river with an average of 2,173
cells/ml for all stations (see Fig. 2.1.7.-1).

     Microscopic examination of the samples collected during both 1975 water
quality surveys disclosed the presence of 108 different phytoplankton taxa
in the Monongahela River.  This  figure undoubtedly represents a somewhat
conservative estimate of all  Monongahela River algae species since several
individuals were only keyed to the generic level  and additional species pro-
bably went undetected because of their bionomy (e.g.  deep water forms and
species atypical of the summer community) or simply because of sampling error,
The observed phytoplankton community was found to contain representative
species from each of the five major taxonomic divisions;  however, the euglen-
ophytes and pyrrophytes were few in numbers of individuals and species.  The
green algae Ankistrodesmus falcatus and Ankistrodesmus convolutus and the
blue-green alga Schizothrix calcicola were found to be numerically dominant
*extremes of mean daily flow along the entire length of the river.
                                       -3-

-------
in most reaches of the river.  During the low flow survey diatom populations
peaked at the headwaters and mouth of the Monongahela.  The headwater peak
was dominated by pennate forms such as Synedra acus and Nitzschia acicularis.
The diatom peak observed at the river's mouth consisted largely of centric
forms such as Melosira granulata and Cyclotella menenghiniana.

     Other numerically important phytoplankters of the Monongahela River are
Actinastrum hantzschii, Scenedesmus quadricauda, and Merismopedia glauca.
A list of phytoplankton genera recently identified from the "Three Rivers"
is provided in Table 2.1.7.-3.

     Algological analyses performed during the low flow survey are deemed to
be especially valuable since the "biological zones" of the Monongahela River
tend to manifest themselves during the critical water quality situation
attendant to such flows.  Williams (11) has noted that algological field
studies performed during low flow are more meaningful, since phytoplankton
populations can develop without the devastating influence of high velocity.
During the 1975 Corps of Engineers (8) low flow survey abrupt decreases in
total phytoplankton concentration were noted between river miles 35 and 24
(see Fig. 2.1.7.-1), a reach in which the Monongahela River water is used
and warmed by the Mitchell and Elrama fossil fueled power plants.

     The chemical analyses performed concurrently with the phytoplankton
studies of the July low flow survey revealed the presence of acid mine drain-
age in the reach between river mile 90 and.60.  The chemistry of this reach
at low flow is governed largely by acid contributions from the Cheat River
(see Section 2.1.6.-Water Quality).  The reach was characterized by low total
phytoplankton concentrations (see Fig. 2.1.7.-1) with a community dominated
by Ankistrodesmus (see Fig. 2.1.7.-2).  Populations of acid sensitive blue-
green algae were noticeably small in this reach.

B.  Periphyton

     Attached growths were collected by the U.S. EPA from a station 0.8 miles
upstream of the Monongahela's mouth in the spring of 1970 (12).  This reach
of the river receives substantial industrial wastewater discharges from the
steel industry and such effluents influence the water quality of the reach
(see Section 2.1.7.6-Water Quality).  The periphyton of this reach was found
to consist primarily of pollution tolerant species of blue-green algae.  Re-
lative to other concurrently sampled stations in the Upper Ohio River Basin,
the periphyton of the lower Monongahela River station appeared to have an
average cellular density, a low generic diversity and a low biomass (see
Figs. 2.1.7.-3, 4, and 5).

C.  Zooplankton

     Limited zooplankton sampling was conducted by the Army Corps of Engineers
(13) at three Monongahela River stations 1n April of 1975.  Nine different
zooplankton taxa were identified, five of these were rotifers (see Table
2.1.7.-4).  These grab samples probably represent a conservative estimate of
total zooplankton species since copepod nauplii and calanoid copepodites were
not even keyed to the generic level.  Moreover, the cool water temperatures
                                       -4-

-------
 and  high  turbidities  typical of April undoubtedly  serve to  limit  rotifer
 populations, which are generally  the principal component of river zooplankton
 (14,  15).

 D.   Aquatic Macrophytes

      Clarkson and Moore  (16) identified twelve species of aquatic  macrophytes
 in the Tygart Valley  River, West  Fork River, and West Virginia portion of the
 Monongahela River during the summers of 1965 and 1966.  Their statistical
 correlations of physico-chemical  and biological data demonstrated  that the
 distribution of aquatic macrophytes within the upper basin  was regulated by
 substrate  type, phosphate content of the substrate, and the degree of water-
 level fluctuation.  Moreover, the environmental perturbations caused by acid
 mine  drainage did not exhibit any statistically significant effect on the
 distribution of these plants.

      A superficial survey of aquatic macrophytes along the  entire  length of
 the Monongahela River was conducted by the Corps of Engineers in  the summer
 of 1975 (8).  Eleven  of Clarkson and Moore's original twelve species were
 observed;  furthermore, eight additional species were detected at  this time
 (see  Table 2.1.7.-5).  Burweed (Soarganium sp.). arrowhead  (Sagittaria lati-
 folia). great bulrush (Scirpus validus). soft rush (Juncus  effusus). and
 spikerushes (Eleocharis sp.) were the most commonly observed species.  Emer-
 gent  macrophyte communities were found to be abundant on the exposed mud
 flats of the L/D 3 and L/D 7 Pools.  Both of these pools are impounded by
 fixed crest dams which permit fluctuation of the pool elevations.  In pools
 behind gated dams the water levels are better controlled; consequently, sub-
 mersed and floating leaved macrophytes are more common than emergent forms
 which under such conditions are essentially restricted to the mouths of tri-
 butary streams.  The  1975 survey disclosed that submersed macrophytes were
 most  common in the Maxwell  Pool, a relatively transparent pool  impounded by
 a gated dam.

 E.  Macrobenthos

      Relative to the other benthic communities of the Upper Ohio River System,
 the macrobenthos of the lower Monongahela River may be characterized by a low
 species diversity (see Fig. 2.1.7.-6).   Several field studies (12, 17, 18, 19)
 performed between 1960 and 1970 inclusive have noted this situation and have
 described a community that is generally dominated by pollution-tolerant
 midges such as Cricotopus bicinctus gr., C_.  exilis  gr.,  C_.  trifasciatus gr.,
 C_. junus, Polypedilum ophiodes  and Chironomus riparius  have also been reported
 as typical benthos of lower Monongahela River.   Benthological  samples collect-
 ed in 1975 at three stations along the entire length of the Monongahela River
 were  likewise numerically dominated by pollution-tolerant oligochaetes and
 chironomids (13).   The samples  revealed a downstream trend  of decreasing
 species diversity and organism  density (see  Table 2.1.7.-6).

     The substrate of the lower Monongahela  consists of soft mud and sand with
 certain areas downstream of McKeesport blanketed by oily sludges originating
 from steel mills.   This situation is not deemed to  be conducive to the develop-
ment of a diverse benthic fauna.
                                      -5-

F.  Fish

     The Monongahela River was originally inhabited by a diverse assemblage
of freshwater fishes, including many pollution-sensitive species.  Fish sampl-
ing performed in 1886 by Evermann and Bellman (20) near Pennsylvania-West
Virginia border detected some forty different species.  However, water pollu-
tion derived from intensive coal mining during the first half of the twentieth
century contributed heavily to the ruination of this fishery (1).  Moreover,
industrial wastewater effluents in the lower Monongahela have further intens-
ified the trend toward a decreased biotic diversity.  Many reaches of the
river, therefore, became either devoid of fish life or populated exclusively
by pollution-tolerant species.

     The fish populations of the upper Monongahela River are still subjected
to environmental stress from acid mine drainage.  Since 1967, the EPA and its
predecessor agencies have conducted five fish population surveys at the Maxwell
Locks and Dams (river mile 61.2), using rotenone in the lock chambers.  Inter-
pretation of this data is tenuous due to the few collections made and the
questionable representativeness of the sampling technique.  Nonetheless, the
data do suggest a biotic recovery in this reach of the river.  In 1967"no fish
were captured and in 1968 only one small bluegill sunfish (Lepomis macrochirus)
was taken.  In 1969 and 1970 the standing crop increased slightly.  However,
pollution-tolerant species such as brown bullhead (Ictalurus nebulosus) and
sunfishes (Lepomis sp.) were dominant.  The sampling program at Maxwell Lock
and Dam in 1973 produced results that Preston (7) believes are indicative of
such biotic recovery.  Total number of fishes, their standing crop, and species
diversity were all found to have increased substantially.  More importantly,
many of the fishes captured at this time were pollution-sensitive species such
as largemouth bass (Micropterus salmoides). channel catfish (Ictalurus punctatus),
and emerald shiners (Notropis a'therinoides).  Table 2.1.7.-7 presents the
changes in abundance and diversity detected during each of the five surveys.
Table 2.1.7.-8 lists the various fish species captured. -

     The favorable results of the 1973 Maxwell fish sampling, in addition to
existing physico-chemical water quality data, prompted the Pennsylvania Fish
Commission to implement a warm water fish stocking program in the upper por-
tion of the Monongahela River.  At the present time, a respectable warm water
fishery exists between the Pennsylvania-West Virginia border and the  town of
Monongahela in Washington County, Pennsylvania (21),

     Pollutional  loads added to the lower Monongahela River consist of indus-
trial wastewaters, domestic wastewaters, and urban runoff.  Acid mine drainage
does enter the river in this reach, but not with  the  same severity as in the
upper reaches.   Fish surveys comparable to  those  conducted at Maxwell Lock
and Dam were also performed at  Lock No. 2 in the  lower Monongahela River Criver
mile  11.2).  The  results of the surveys (1967-1973) at this station,  although
exhibiting an increase  in standing crop, demonstrated very little  improvement
in  the quality of the fishery  (see Table 2.1.7.-7).   Collections were dominated
by  pollution-tolerant species  such as carp  and brown  bullhead (see Table 2.1,7.-
8).

G.  Ecologically Important Basin Streams

     The Tenmile Creek Basin, Dunkard Creek Basin,  and the lower Youghiogheny
River support significant populations of warm water game and pan fishes (21).
Smallmouth bass (Micropterus dolomieu) constitute the main warm water angling
attraction in these streams.  The most important cold water fisheries are
located in the Youghiogheny River Basin in Fayette  County, Somerset County,
and a small corner of Westmoreland County.  Big Sandy Creek, Little Sandy
Creek, White's Creek, Laurel Hill Creek, Indian Creek, Dunbar Creek and the
Upper Youghiogheny main stem are among the most significant cold water streams
(22).


2.1.7.3.  THE ALLEGHENY RIVER

A.  Phytoplankton

     Algological surveys were performed by the Corps of Engineers (23) in the
navigable reach* of the Allegheny River during an intermediate flow regime in
August 1976, an intermediate flow regime in June 1977, and a high flow regime
in July 1977.  The average total phytoplankton concentration for the entire
navigable reach was determined to be in excess of 6,500 cells/ml.

     The Allegheny River phytoplankton community is considerably more diverse
than that of the Monongahela River.  A total of 217 algal taxa were identified
in the navigable reach of the Allegheny during 1976 and 1977.  The greatest
algal diversity (118 taxa) for any single navigation pool was detected at
the L/D 9 Pool.  Centric diatoms and chlorophytes were found to dominate the
Allegheny River phytoplankton community.  The most common genera were Cyclo-
tella. Melosira. Asterionella. Scenedesmus. Dictyosphaerium. and a small
unidentified coccoid chlorophyte resembling Palmella.

     The significant biological zonation noted by the Corps of Engineers (8)
in the Monongahela River was not observed in the Allegheny River (23).  How-
ever, a trend  toward decreased chlorophytes in relation to centric diatoms
was observed near the middle of the  navigable reach.  Moreover, acid-sensitive,
blue-green algae were observed to paradoxically  increase  in a reach polluted
by acid mine drainage derived from the Kiskiminetas River; it was hypothesized
that this  phenomenon may be  a response to increased nutrient levels.

B.   Periphyton

     Studies conducted between 1975  and 1977 revealed that the lower Allegheny
River periphyton community  at New Kensington, Clinton, and Kittanning  is com-
prised almost  entirely of diatoms; however, a few chlorophytes (Oedogonium,
Scenedesmus, and Pediastrum) were also noted as  occurring at these locales
(24)!   In  contrast,  a study  conducted by  EPA (12) in  1970 near the mouth of  the
Allegheny  described  the  periphyton community as  consisting primarily of blue-
green algae with several chlorophytes and very few diatoms  (see  Figs.  2.1.7.-
3, 4, and  5).
 *lower  72 miles

                                       -7-

-------
C.  Zooplankton

     Zooplankton collected in September of 1975 near New Kensington, Clinton,
and Kittanning consisted of eight taxa of Cladocera, three taxa of copepods,
twelve taxa of rotifers, and two taxa of protozoans (24).  The total zoo-
plankton concentrations at these three stations ranged between 409 and 1,190
individuals/M3.  The most common cladocerons were Pleuroxus sp. and Bosmina
longirostris.  Most of the copepods detected were in the larval stage of
development (nauplii).  Kellicottia bostom'ensis and Kellicottia sp. accounted
for a high numerical percentage of the rotifers.

D.  Aquatic Macrophytes

     In 1977 twelve taxa of vascular aquatic plants were identified in the
L/D 3 and L/D 6 Pools of the Allegheny River (25) (see Table 2.1.7.-9).
Sagittaria-EIeocharis communities were found to be common in backwater areas
with silt and soft mud bottoms.  An especially extensive Sagi ttaria-Eleochari s
community was noted in the L/D 3 Pool near Tarentum.  Justicia was cited as
the most common aquatic vascular in the lower Allegheny; it was typically
found growing on lightly silted, gravel shoals and around islands.  Justicia
was noted as being abundant in areas where the river channel was braided,
especially in the L/D 6 Pool near Ford City.  Koryak (25) notes that Justicia
is absent from the Monongahela River; he speculates that this situation is
due to the fact that the Monongahela, unlike the Allegheny, "has a generally
undiversified ditch-like channel and no islands."

E.  Macrobenthos

     The Federal Water Pollution Control Administration sampled the Allegheny
River for benthic macroinvertebrates in 1966 and 1967 (18, 26).  Samples
collected upstream of the confluence of the main stem with the Kiskiminetas
River generally contained numerous benthic organisms from many invertebrate
taxa, a.situation indicative of a relatively unpolluted waterway.  Hydropsychid
caddisflies were numerically dominant 1n many of the samples.  In contrast,
samples collected downstream of the confluence with the acid mine drainage-
degraded Kiskiminetas River (see Section 2.1.6.-Water Quality) contained few
organisms and were dominated by pollution-tolerant chironomids and oligo-
chaetes.  Samples collected near Pittsburgh in the spring of 1970 (12) like-
wise revealed a sparse, undiversified benthic community (see Fig. 2.1.7.-6).

     Recent studies conducted by the Corps of Engineers (24) 1n 1975 and 1977
between river miles 18 and 51 revealed that chironomids are the most prevalent
group of Allegheny River macrofaenthos, with Procladius sp. being the most
abundant individual.  However, tubificid worms generally constituted the
majority of the biomass.  The mayflies Stenonema interpunctatum, S.. nepotellum,
and Hexagenia limbata were also often detected, as were the caddisflies
Hydropsyche betteni. Neurecllpsis sp., and Nyctlophylax sp.

F.  Fish

     Fish sampling conducted from 1975 to 1977 at six stations between river
miles eighteen and fifty-one revealed the presence of thirty-two species of
                                      -8-

-------
fish in the Allegheny River (24).  Various species of game fish including
largemouth bass, smallmouth bass, walleye, northern pike, and channel catfish
were captured during this survey (see Table 2.1.7.-10).  Over the past several
years there has been a surge of angling interest along this reach.  The authors
are aware of significant catches of walleye and smallmouth bass from "fishing
holes" near Kittanning (r.m. 45.5), Acmetonia (r.m. 14.5), and even as far
downstream as Sharpsburg (r.m. 6.6).

G.  Ecologically Important Basin Streams

     The majority of ecologically important Allegheny River tributaries drain
the northern-most Pennsylvania ORBES counties. Tionesta, Sugar, and East
Hickory Creeks in Forest County, Oennison Run in Venango County, Mill Creek,
School house Run, and the North Fork in Jefferson County are just a few of the
streams supporting populations of native brook trout.  In the southern portion
of the basin (Westmoreland County) Powder-mill Run and Loyalhanna Creek are
cold water streams of special importance.  The ecology of Powdermill Run has
been extensively studied by the  staff and associates of the Carnegie Museum
of Natural History, consequently, this stream represents a "natural laboratory"
for which there already exists a large data base.  Loyalhanna Creek is"of
particular importance because, as noted in Section 2.1.4.-Terrestrial  Ecology,
it contains one of the few remaining hellbender populations in southwestern
Pennsylvania.

     Valuable warm water fisheries of the Allegheny River Basin occur  in
French Creek, Buffalo Creek,  and the Allegheny main stem.  French Creek is
biologically unique in that it harbors the most diverse assemblage of  fresh-
water mussels in the Pennsylvania ORBES region.


2.1.7,4  THE UPPER OHIO RIVER (.PA)

     Ecological conditions  in the first forty miles of the Ohio River  will  be
dealt wtth briefly herein,  since the "ORBES  Preliminary Technology Assessment
Report"  (27) includes a biological overview  of the entire  river.

A.   Phytoplankton

      Field studies of the Upper  Ohio River (28, 29) have described a  phyto-
plankton community dominated  by  Melosira. Scenedesmus, Ankistrodesmus, Chlamy-
domonas, Cyclotella, and Dictyosphaerium.  Surveys conducted  by the  Corps of
Engineers  (.29)  in the summer  and fall of  1974 indicate that  during  inter-
mediate  flow regimes the total phytoplankton concentration ranges  between two
and  four thousand cells  per milliliter.   During high  flows the  community may
be  reduced and/or diluted  to  a few hundred cells  per  milliliter or  less.  The
available  data  indicate  that  phytoplankton concentrations  tend  to  be  greatest
 in  the  lower sections of navigation  pools where velocities are  low.

B.   Periphyton

      Attached  growths collected  fay the  EPA in the spring  of  1970  (12)  were
dominated  by blue-green  algae which  comprised 50-86%  of  the  cell  count at all
                                       -9-

-------
but one of the sampling stations (see Fig. 2.1.7.-3).  Diatoms were also sign-
ificant community members, comprising 8-32% of the cell count at, likewise,
all but one station.  The station deviating from the normal  blue-green algae/
diatom phycoperiphyton assemblage is located immediately downstream of the
Allegheny County Sanitary Authority's (ALCOSAN's)  wastewater effluent.  At
this station green algae comprised fifty percent of the cell count, a chloro-
phyte  density greater than those observed at all  other stations.  More impor-
tantly, the conspicuous presence of protozoans* downstream of ALCOSAN (13%
of the cell count) suggests that this waste source induces observable changes
in the composition of the periphyton community.  Increases in cellular density
and chlorophyll content further downstream of ALCOSAN (see Figs.  2.1.7.-3 and
2.1.7.-5) were attributed to nutrient enrichment from this point source.
Approximately fifteen miles downstream of the outfall these effects begin to
reverse themselves.  It should be noted however, that these observations are
somewhat dated and that ALCOSAN's conversion to secondary treatment in 1974
may have eliminated or lessened spatial differences in the composition of
attached communities.

C.  Zooplankton

     The Beaver Valley Power Station's pre-operational environmental impact
studies characterized the zooplankton community of the Upper Ohio River (river
miles 31-40) as being dominated by rotifers.  Although cladocerans and cope-
pods were frequently detected, rotifers always comprised at least 33% (by
numbers) of the zooplankton and usually constituted over 50% (30).  Aperiodic
plankton analyses performed by the authors over the past nine years confirms
this rotifer dominance for the entire Upper Ohio River in Pennsylvania.  Common
rotifers include species of Brachionus, Keratella, Polyarthra, and Synchaeta.
Cladocerans consist mainly of Bosmina. Diaphanosoma, Ceriodaphnia, and Moina
while copepods are represented by Cyclops, Tropocyclops, Mesocyclops, and
Diaptomus.

0.  Aquatic Macrophytes

     Heavy industrialization along the banks of the Upper Ohio River has
greatly reduced the availability of sites for the growth of aquatic vasculars.
Consequently, emergent macrophytes are relatively scarce.  A survey conducted
by the Corps of Engineers in 1975 identified only ten narrow bands of signi-
ficant growth on the reach within the Pittsburgh Corps' District  (31).  These
bands were generally located at sites on the back channel sides of islands.
Sagittaria and Eleocharis were identified as the most common genera although
Sparganium was frequently detected in deeper water.

E.  Macrobenthos

     The most recent studies (12, 30) indicate that the benthic fauna of the
Upper Ohio River  is composed primarily of oligochaetes with lesser numbers of
the midges Psectrocladius sp., Cricotopus gr. bicinctus, and C_. trifasciatus.
Minor components  include  the amphipod Crangonyx sp., the crayfish Qrconectes
sanborni,  the damselfly Enallagma exulans, and several other miscellaneous
invertebrates.  The EPA field study of 1970  (12) noted that oligochaetes
were most  abundant  at  three stations  (see Fig. 2.1.7.-6) immediately downstream
 *Protozoans  thrive  on  bacteria and minute sewage particles.

                                       -10-

-------
of significant sources of iron-bearing wastewater;  it was hypothesized that
iron precipitates and filamentous iron-bacteria provide a more suitable sub-
strate for these burrowing organisms than bare rocks.

F.  Fish

     Lock chamber studies conducted annually 1968-1970 and 1975-1976 at
Dashields Lock and Dam (river mile 13.3)  have disclosed the presence of thirty-
four species of fish (see Table 2.1.7.-8} for the entire period of examination;
however, only sixteen to nineteen species have been captured in any given year.
Data from each survey year reveals that the Dashields sampling station typically
exhibits a lower fish species diversity than downstream stations.   Along the
entire length of the Ohio River, eighty-two species of fish have been captured
during the history of these surveys.  Several individual downstream stations
have yielded more than forty species for the period of examination and in
excess of thirty species for individual years (32).  Moreover, fish biomass
estimates for the period of record at Dashields shows that 76% of the biomass
is composed of rough species, whereas at most downstream stations these
pollution-tolerant species constituted less than 50% of the biomass.

G.  Ecologically Important Sub-basin Streams

     Most streams in the Upper Ohio River Basin would be incapable of support-
ing a naturally reproducing cold water fishery and much of its associated
biota even if all pollutional insults were removed tomorrow (33).  This seem-
ing pecularity is due to the hydrologic, topographic, and geologic character-
istics of the land area which favor low gradient, warm water streams.  The
notable exception to this generalization is the portion of Slippery Rock
Creek and its tributaries located in McConnells Mill State Park (Lawrence
County).  Several warm water streams are, however, significant in that they
support natural populations of small mouth  bass and stocked populations of
walleye and tiger muskellunge.  Areas of particular importance are:

     a).- Connoquenessing Creek in Butler, Lawrence, and Beaver Counties
     b).  The lower reaches of Slippery Rock Creek in Lawrence County
     c).  The Wheeling and Buffalo Creek Watersheds in Greene and Washington
          Counties
     d).  Portions of the Shenango River in Mercer and Lawrence Counties


2.1.7.4  EXECUTIVE SUMMARY

     The "mishmash" of taxonomic names so typical of environmental impact
statements, ecological baseline documents, and natural resource inventories
provides lengthy lists of species, which generally defy analysis and therefore
prove to be nonutilitarian.  Conversely, detailed statistical analysis of
aquatic ecological data for the entire Pennsylvania ORBES region is not only
impractical, but dangerous, since field studies are aperiodic and often cursory.
Perhaps the most logical method of simplifying this portion of the baseline
document is to rank areas as to their relative diversity of aquatic life.  For
example, most western Pennsylvania fishermen are aware of the following trend:
                                       -11-

-------
                           QUALITY OF SPORT FISHERY

          Upper Allegheny River > Lower Allegheny River > Upper

          Monongahela River > Ohio River in Pa. > Lower Monongahela

          River

Relative rankings become more difficult to assign as one considers other forms
of aquatic biota and tributary streams.  Nonetheless, in Figure 2.1.7.-7 we
attempt to make some generalizations for entire counties based upon the diver-
sity of fish, other fully aquatic vertebrates, freshwater mollusks, and
aquatic insects in the flowing waters of western Pennsylvania.  These relative
rankings are based upon our field collections, and the field experience of
friends and colleagues in the region, as well  as species information provided
in recent reports of state and federal  environmental agencies.

     As can be seen in Figure 2.1.7.-7, the most diverse aquatic communities
are located in sparsely populated areas to the north and east of Pittsburgh.

     survival unlikely without special protective measures.
 2.  Threatened :  Not under immediate threat of extinction in the state, but
     occurring  in such small numbers and/or in such restricted habitat that it
     could quickly cease to be a part of the state fauna.
 3.  Indeterminate:  Apparently threatened or uncommon to rare, but  insufficient
