INTRODUCTION
At the request of the Water Division and in cooperation with the
Western District 'Office, the Central Regional Laboratory Biology Section
was asked to conduct a biological survey of the Fox and Wisconsin Rivers
at Portage, Wisconsin. This was done in support of an Environmental Impact
Statement (EIS) currently in preparation.
This report includes biological findings during three different sampling
periods, namely June 12-16, July 10-13, and August 14-17, 1978. In addition,
to general physical chemistry such as temperature, pH, dissolved oxygen and
specific conductance, the biological parameters collected include phytoplankton,
zooplankton, periphyton, macroinvertebrates, and chlorophyll. During the
August sampling period, fish sampling was conducted on both rivers.
It should be noted that on the last day of the June survey, the field
notebook describing the sampling locations and results of general chemical
analysis performed in the field was lost. Biologists in the field reconstructed,
to the best of their knowledge, all information that was included in the
notebook. Because most of the data had been collected within a two day period,
the biologists are confident in their reconstruction descriptions of each
sampling location as well as the general chemical and physical data collected.
-------
SUMMARY
Biological conditions in the Wisconsin and Fox Rivers varied from
station to station and from one sampling period to another, resulting in
a shift from moderately enriched conditions (Mesotrophic) to more seriously
enriched conditions (eutrophic). The following is a brief classification
of each of the three stations studied on both rivers.
1. Station one on the Fox River was considered to be moderately to
heavily enriched, while the Wisconsin River at Station one was
classified as being moderately enriched.
2. Both rivers at Station two appeared to be somewhat similar in terms
of biological productivity during the June and July sampling period.
However, in August, there seemed to be a trend on the Fox River
toward a greater number of pollution tolerant forms, while the
Wisconsin River remained relatively constant.
3. The Wisconsin River at Station three was more enriched as compared
to the same station on the FOX River throughout most of. the study
period. During the latter part of the study both rivers showed a
decline in water quality as shown by the disappearance of certain
pollution intolerant forms.
-------
STATION DESCRIPTION
Fox River
Station one was located approximately 3/4 of a mile downstream of
Swan Lake. The River, at this point, was 20 meters wide with a depth of one
meter. Submerged aquatic vegetation covered the sampling area. The bottom
substrate consisted of soft and "mucky" organic matter with numerous empty
snail shells. The surrounding land was a marsh-type area with numerous
grasses, cattails, and shrubs lining the shoreline.
Station two was located at Highway 33 East Bridge approximately one-
quarter of a mile downstream of the Portage Sewage Treatment Plant. The
channel width was 15 meters, with a depth of one meter. The bottom substrate
consisted of sand - and "mucky" organic matter. The shoreline was lined
with tall grasses and small shrubs. Submerged aquatic vegetation covered
the sampling site. At certain times of the year, duckweed lines the sides
of the channel.
Station three was located downstream of the Portage Sewage Treatment
Plant at the Clark Street Bridge. The channel width was 15 meters. The
depth of the river was one meter with a bottom substrate consisting of rock,
sand, "mucky" organic matter, and numerous empty snail shells. The shoreline
was lined with grasses and cattails. At times, duckweed lines both sides
of the channel and submerged aquatic vegetation covers the sampling site.
Wisconsin River
Station one was located approximately one mile upstream of Highway 78
Bridge at the point where the river starts to bend on the left bank. An
island was located one-half mile upstream of the station where the river
seperates into two channels. Channel width was 250 meters. The bottom
substrate consisted of fine to coarse sand. Numerous trees and shrubs lined
-------
the left bank of the river, while a sandy shoreline with grasses lined
the right bank. Due to the width of the channel, three substations were
located along a transect across the river. Substations A and C were
located 50 meters from the right and left bank respectively, while substation
B was located in the middle of the channel.
Station two was located across from the radio station WPDR antenna
on the right bank of the river. The channel width was 200 meters. The
bottom substrate consisted of fine to coarse sand. Channel depth was between
1.0-1.5 meters. This section of the Wisconsin River consisted of numerous
sandbars and islands interdispersed with very shallow areas. The main flow
of the river appeared to be along the left bank. The shoreline of both sides
was lined with numerous trees and shrubs. Due to the width of the channel,
three substations were taken along a transect across the channel. Substations
A and C were located forty meters from the right and left banks, respectively.
Substation B was located .in the middle of the channel.
Station three was located adjacent to the public boat access landing
at Dekorra Park. The channel width was 200 meters with a bottom substrate
consisting of fine to coarse sand. Three substations were located along a
transect across the river. Substations A and C were located forty meters
from the right and left banks, respectively. Substation B was located in
the middle of the channel. The depth at this station was 1.5-2.0 meters.
The shoreline along the left bank was lined with numerous trees, whereas the
right bank was lined with sandstone cliffs.

METHODS
Macroinvertebrates
Macroinvertebrates referred to in this report are aquatic organisms
that can be retained by a U.S. Standard No. 30 sieve (28 mesh per inch) and
live at least part of their life cycle within or upon underwater substrates.
Qualitative raacroinvertebrate samples were obtained by washing organisms
from rocks, logs and other substrates at the sampling sites. Organisms were
washed into a Surber sampling net. All organisms collected were placed into
a quart glass jar and preserved with 5% formalin.
Quantitative macroinvertebrate samples were obtained by using a Ponar
dredge. The samples were washed in the field through a No. 30 mesh sieve.
All organisms collected were placed into a quart glass jar and preserved
with 5% formalin. Two indepdendent samples were taken at each sampling station.
Phytoplankton
Phytoplankton refers to microscopic plants (algae) suspended in a
body of water that are incapable of sustained mobility in directions counter
to the water currents.
Phytoplankton samples were obtained by taking a grab sample at the waters
surface using a 500 ml plastic bottle. Samples were preserved with lugols
solution.
Zooplankton .
Zooplankton refers to the microscopic animals of the plankton community
which graze upon the phytoplankton as a source of food.
Quantitative zooplankton samples were obtained by using an eight liter
Nlskin bottle. Four independent grab samples were obtained approximately
one meter below the waters surface at each station. The contents of each
6
-------
Niskin bottle were then pooled. The organisms in the pooled samples were
concentrated by passing the sample through a plankton funnel fitted with
a 53 p mesh net. The sample was placed into a 500 ml plastic bottle,
appropriately labeled and preserved with 5% formalin.
Chlorophyll
Chlorophyll refers to all plantlife containing a pigment known as
chlorophyll^. The measurement of this pigment can yield some insight into
the relative amount of alga standing crop. Chlorophyll samples were prepared
in the field by filtering a known aliquot of water through a Gelman A/E
glass fiber filter. A MgCO- suspension was then filtered through to prevent
the sample from becoming too acidic. The filter was immediately wrapped in
aluminum foil and placed inside a metal cannister which had been appropriately
labeled. The sample was then placed on dry ice for transport back to the
laboratory.
Periphyton
Periphyton refersito an assemblage of organisms that grow on underwater
subsrtates, and includes such organisms as algae, molds and protozoa. All
of the organisms are not necessarily attached to the substrate but at least
live in association with attached organisms.
Periphyton were collected on I"x3" glass microscope slides by means of
a periphytometer. The length of exposure was four weeks, at which time the
slides were retrieved. The slides collected were placed into a 100 ml
plastic bottle and preserved with lugols solution.
-------
Fish-Electrofishing
A boat mounted pulsating direct current electrofishing unit was
utilized. (Colfelt electronics model W-20). The electric current was
directed into the water through a pair of steel cables which were suspended
from booms extending from the bow of the boat. Each sampling area was
electrofished for a period of between 20-26 min.
All stunned fish were dip-netted from the water and transferred to a
holding tank, where they recovered from the electroshocking. All fish captured
were identified to species when possible, counted, measured, weighed, and
returned to the water.
Chemistry
Dissolved oxygen and temperature were measured using a YSI model 54A
oxygen and temperature meter (Yellow Spring Instrument Co.). The oxygen
meter was calibrated daily against the lodometric method for D.O. analysis
as outlined in Standard Methods for the Examination of Water and Wastewater,
14th edition 1975. The pH was measured using an Oion lonalyzer model 407A
pH meter. Specific conductance was measured using an Industrial Instruments
model RB3 Solu Bridge conductivity meter and probe.

-------
CUSTODY PROCEDURE
Custody procedures were followed throughout the study. ^.AIl samples
X"
/
collected at a particular station were immediately placed into ice chests.
While the stations were being sampled, ice chests were kept secured in a
government vehicle. At the end of each day, all samples collected were
recorded onto custody sheets and signed. Samples were returend to the ice
./'
chest and sealed with custody labels for transport back to the laboratory.
Back in the laboratory, custody procedures were followed as prescribed by the
Central Regional Laboratory Custody Manual.
RESULTS
Chemistry
General chemistry data is presented in Table I. As can be seen,
specific conductance concentrations were greater in the fox River than the
Wisconsin River. Between June and August, specific conductance concentrations
in the fox River ranged between 360-560 yohms/cm compared to a range of
140-160 yohms/cm in the Wisconsin River. The pH and temperature were similar
in the two rivers. The two river systems did differ with regard to the amount
of dissolved oxygen present at the various stations. In the Wisconsin River
dissolved oxygen concentrations remained between 7.1-8.8 mg/1. However, in
the Fox River, a significant oxygen sag was present at Stations two and three,
located downstream of the Portage Sewage Treatment Plant.
In July and August, Station two had dissolved oxygen concentrations of
2.6 to 3.8 mg/1, while Station three had concentrations of 2.2-3.9 mg/1.
In June, Station two had a D.O, concentration of 7.0 mg/1. This higher D.O.
concentration compared to the values obtained in July and August could be
due to the higher D.O. water from Station one (12.2 to 14.A) flowing into
Station two.
-------
Fish
Results of the fish shocking are presented in Tables 2, 3, and A.
Five species of fish were captured from station one on the Fox River. The
most abundant species was Lepomis microlophus (Redear sunfish). A total
of four fish were caught. The other species present were bowfin (Amia calva),
green sunfish (Lepomis cyanellus), brown bullhead (Ictalurus nebulosus) , and
yellow perch (Perca flavescens). Fifteen young of the year sunfish were
also retrieved but these were not identified to species.
In the Wisconsin River, only two species of fish were present at
Station one. The most abundant fish present were minnows, which were not
identified to species. One large (64 oz.) quilback carpsucker (Carpoides
c.yprinus) was caught. At Station two, four species of fish were captured.
Only one of each of these species was retained. The species represented were
quilback carpsucker (Carpoides cyprinus), smallmouth bass (Hicropterus
dolomieui), yellow perch (Perca flavescens), and minnows. Station three
was represented by the following fish species; quilback carpsucker (Carpoides
cyprinus), largemouth bass (Micropterus salmoides), silver redhorse (Moxustoma
anisurum), and minnows. Minnows were the most abundant group represented.
Zooplankton
Fox River
Except for June, Station one supported a considerably larger zooplankton
population than Station three (Table 5,6). This was most evident in July
and August when Station one supported 161 and 188 org/1 respectively, compared
with Station three, which had only 34 org/1 in July and 17 org/1 in August.
Members of the Rotifera dominated the zooplankton present during the study.
The rotifera was most represented by Keratella cochlearis, Polyarthra vulgaris,
10
-------
Keratella earlinae and Trichocerca sp. Members belonging to the order
copepoda were present In relatively low numbers. The copepoda, during all
three months, were represented by species in the early form of development
(Cyclops Juveniles and Nauplii).
Wisconsin River
Throughout the study period, Station one supported a larger zooplankton
population than Station three. This difference was most noticeable in
June and July. In June, Station one had a total of 139 org/1 compared to
98 org/1 at Station three, while in July, Station one contianed 65 org/1
compared to 34 org/1 at Station three. In August, there was only a slight
difference between Station one (28 org/1) and Station three (24 org/1).
Members of the Rotifera dominated the zooplankton present during the study.
The Rotifera were represented by Keratella cochlearis, Syncharta sp.,
i
Trichocerca similis, and Polyarthra vulgaris. The Copepoda were represented
by early life stages of species (Cyclops juveniles and Nauplii). These
species, however, never became numerically important.
Phytoplankton
Fox River
*
Throughout the entire study period, Station one supported a considerably
larger phytoplankton population than Stations two and three (Tables 7, 8 and 9)
In June, Station one was dominated by the blue-green algae, namely Anabaena sp. ,
and Aphanizomenon flos aquae. However, later in the summer, a noticeable
change in the algal population occurred. By July, the flagellated algae
consisting of Cryptomonas sp., and other miscellaneous flagellate species
increased substantially from June (612 cells/ml to 5860 cells/ml), thus
accounting for the dominance by both the blue-green algae and flagellates.
11
-------
By August, the flagellate population continued to Increase reaching a
concentration of 12,970 cells/ml. The blue-green population had decreased
from a concentration of 7250 cells/ml in July to 1130 cells/ml in August.
Thus, in August the flagellate population dominated comprising 87.0 per
cent of the population.
Station two showed shifts in population numbers and composition between
June and August. In terms of cell concentration in June, Station two supported
a population of 5253 cells/ml. However, by July, the numbers of phytoplankton
encountered decrease to 2940 cells/ml and by August to 2720 cells/ml. During
this same time period, changes in the dominant' algal forms also changed.
In June, the centric diatoms consisting of Cyclotella spp., comprised 68%
of the species, however, by July the flagellated algae "became dominant (62%)
and this trend continued through the August study.
Station three, unlike Station two, showed an increase in the phytoplankton
population from June until August. In June, the algal cell concentration
was 2907 cells/ml. By July, the algae had increased to 6230 cells/ml, and
in August, to 10,940 cells/ml. With regard to species composition, the June
study showed a diverse population of all major groups of algae with no one
form showing complete dominance. However, by July, the flagellated algae
(consisting of Cryptomonas sp_.and misc. flagellates) began to increase in
numbers and became the dominant algae. This group continued to dominate in
August.
Wisconsin River
Station one on the Wisconsin River showed shifts in species composition
between June and August. In June, the algal population was dominated by the
blue-green alga, Aphanizomenon flos-aquae, the flagellated algae comprised
of Cryptomonas erosa and miscellaneous flagellates and the centric diatom
12
-------
Melosira spp. In July, diverse algal population existed with no major
algal group showing complete dominance. However, by August, the flagellated
algae had continued to increase, and along with the centric diatoms became
the dominant algal forms. The flagellated algae were largely comprised of
Cryptomonas ovata, Chlamydomonas sp., and miscellaneous forms. The
centric diatoms were represented largely by Melosira spp.
Station two exhibited a population structure similar to Station one.
Throughout the study, the flagellated algae and centric diatoms dominated.
The species represented were similar to those present at Station one.
Station three, during the study period, consistantly supported a
larger phytoplankton population than Stations one and two. In terms of cell
concentration, phytoplankton numbers changed little between June and August.
In June, 9486 cells/ml were present, compared to 9510 cells/ml in July and
11,840 cells/ml in August. Although cell concentration changed little
during this time period, species composition increased. In June, the flagellates,
centric diatoms, and blue-green algae dominated. Species represented were
the same as were present at Station one. By July, the centric diatoms
became less important and the flagellates and blue-green algae dominated.
In August, the blue-green population decreased substantially and flagellates
and centric diatoms became numerically important. The green algae also
began to increase in August being comprised predominantly of Crucogenia
.quadrata and Ankistrodesmus falcatus.
It should be noted that throughout the study, green particulate matter
visible to the naked eye was suspended in the water of the Wisconsin River.
At all sampling stations, biological examination of the water in June and
July did not show any unusual increase in any of the phytoplankton species
encountered. In August, this green particulate matter continued to "be
present, and due to heavy winds at the time of sampling, a large amount of
13
-------
this material began to collect along the Eastern shoreline between
stations one and two. Biologocal examination revealed the substance to
be the algal species Microcystis aeruginosa. This species had reached
bloom conditions in August and the heavy winds were accumulating the
cells into a mat along the windward shoreline.
Chlorophyll
Fox River
Station one showed a substantial increase in the amount of chlorophyll a^
present in the water compared to Station three during the months of June
and July (Table 10). This difference was most noticeable in the June survey
when Station one had an average chlorophyll a^ concentration of 47.5 yg/1,
compared to 9.13 yg/1 at Station three. It should be noted that this difference
was probably due to the large number of phytoplankton cells observed suspended
in the water at Station one and in Swan Lake. The algal population was
apparently approaching "bloom" conditions, although cell counts of water
samples did not show a "bloom" condition to be present.
This large population of algae was not observed to be present in July,
accounting for the significantly lower chlorophyll a^ values obtained at
Station one during July. However, there still remained a substantial
difference in the amount of algal biomass produced at Station One (15.9 yg/1)
compared to Station three (6.72 yg/1).
In August however, unlike the previous two months, Station three showed
a substantial increase (25.1 yg/1) of chlorophyll £ present compared to that
at Station one (9.0 yg/1).
14
-------
Wisconsin River
Station three throughout the study period contained a greater amount
of algal biomass compared to Station one. The most significant difference
occurred in June when Station three had an average chlorophyll a_ value
of 23.1 yg/1, while Station one had a value of 13.A yg/1. This trend
continued during July and August, however, the differences between the two
stations was not as pronounced. In July, Station one had an average chlorophyll a_
value of 10.4 yg/1, while Station three had a concentration of 13.3 yg/1. In
August, Station one had a value of 22.0 yg/1, while Station three had 27.7 yg/1
of chlorophyll a^ present.
Periphyton
Fox River
Examination of the periphyton community in July showed Station one on
the Fox River to be more productive than Station two further downstream.
As one can see from Tables 11 and 12, Station one supported 23,298 cells/mm2
compared to only 5978 cells/mm2 at Station two. Unfortunately, the periphyto-
meter at Station three was either lost or stolen, thus no comparison between
the other stations could be made.
With regard to species composition, Station one was dominated by the
blue-green algae, represented by Oscillatoria sp. and Coelosphaerium
kuetzingianum and the pennate diatom Cocconeis pediculus. Station two was
dominated by Oscillatoria sp. and Cocconeis pediculus.
Wisconsin River
The periphyton community on the Wisconsin River showed Station one
to be less productive than either stations two or three. Tables 11 and 12
shows that in July, Station one supported 221 cells/mm2, Station two
15
-------
4928 cells/mm2 and Station three an average of 4948 cells/mm2.
Species composition showed Station one to be dominated by the centric
diatom Melosira spp. Station two was dominated by Oscillatoria sp., and
Cocconeis pediculus. Station three was best represented by the blue-green
algal species Aphanizomenon flos-aquae and Oscillatoria sp., and by the
pennate diatom Cocconeis pediculus.
Macroinvertebrates
Fox River
The results of the qualitative and quantitative macroinvertebrate
samples are contained in Table 13. Station one data showed a great diversity
0^.
of organisms in the qualitative samples for all months sampled (June - 24 taxa,
July 24 taxa, August - 37 taxa). For the most part, these organisms were
associated with the stream margins, in and among the rooted vegetation.
Quantitative samples indicated habitation of the bottom sediments by
a highly diverse population in early summer (31 different taxa in June) and
moderate diversity in July and August, with 19 and 20 taxa respectively.
The population at Station one showed a mixture of pollution tolerant,
facultative and intolerant forms.
Station two had a high diveristy in the qualitative sample for July
(43 taxa) and a lower diversity in August (12 taxa). Ponar samples showed
a decrease in diversity as the summer progressed. This was most likely
due to the decrease in dissolved oxygen and an increase in water temperature.
Also, the intolerant forms were not found in the August samples, as they
had been in June and July.
16
-------
Taxa diveristy decreased at Station three during the summer months.
The quantitative samples had 45 taxa in June, 20 taxa in July, and 15 taxa
in August. Here again, only the tolerant organisms were encountered at the
end of the summer. The qualitative samples had a high diversity of organisms
collected from among the abundant aquatic vegetation and along the margins
of the stream. The pollution intolerant forms found thorughout the summer
were for the most part, those organisms which live at the water - air
interface, and on the vegetation near the surface of the water (i.e., -
Helisoma limosa and Anmicola integra).
Wisconsin River
Table 13 contains the qualitative and quantitative macroinvertebrate
data collected for the Wisconsin River during June, July and August. The
quantitative data for all stations, for all months, exhibited low diversity
and low total numbers of individuals. The moderately fast river current
and substrate composition (a mixture of fine to coarse sand) are- responsible
for the reduction of the organisms, since such conditions greatly inhibit
perminant colonization of the bottom sediment by the macroinvertebrate groups.
The extensive colonization of the artificial substrate periphyton
samples and heavy utilization of overhanging trees and submerged vegetation
by organisms indicates that where the shifting sand substrate can be avoided,
a diverse population of individuals (as high as 34 taxa at Station three in
July) can develop. The decrease in the number of taxa for the month of
August on the Wisconsin River is probably due to the drastic drop in the
water level, which exposed large sections of previously inhabited areas
of the river bed.
17
-------
The raacroinvertebrate populations at all''stations were a mixture of
pollution tolerant, facultative, and intolerant forms. This existed through-
out the summer.
DISCUSSION
Station 1
When comparing Station one on'the Fox River to that on the Wisconsin
River, it appears that during the study period, the Fox River is biologically
more productive than the Wisconsin River. This is supported by the fact
that during the entire study period, phytoplankton cell concentrations were
substantionally greater in the Fox River than the Wisconsin River. In June,
the Fox River supported 9741 cells/ml, in July, 14,300 cells/ml and in August,
14,910 cells/ml. This compares to Station one on the Wisconsin River, which
in June, produced only 7344 cells/ml, in July 5680 cells/ml and in August,
8679 cells/ml. Examination of the periphyton community present during the
July study, further supports the fact that Station one on the Fox River is
more productive than that on the Wisconsin River. The Fox River supported
23,298 cells/mm2 compared with only 221 cells/mm2 on the Wisconsin River.
Except for August, chlorophyll ji concentrations showed greater
productivity in the Fox River. Zooplankton populations (except in June)
were also considerably greater in the Fox River.
It should be noted that in July and August, several species of rotifers
were present at Station one on both the Fox and Wisconsin Rivers, which are
indicators of eutrophic conditions. Although these species were present in
relatively low numbers, their presence may indicate that these stations are
approaching eutrophic conditions. The species represented were Brachionus
angularis, Keratella cochlearis, P_. tecta, Trichocerca multicrinis, Filinia
longiseta and Pompholyx sulcata.
18
-------
In.terms of macroinvertebrate findings, Station one qualitative samples
from the Wisconsin River had a lower diversity of taxa .(15) as compared to
the Fox River (29). Quantitative substrate samples also showed the Fox
River at Station one to be more productive than the Wisconsin River for the
same station. Both rivers at this location had benthic communities composed
of tolerant, facultative and intolerant forms, which was characteristic
throughout the summer.
Based upon the biological parameters measured at Station one, the Fox
River was classified as mesotrphic to eutrophic in nature, while the
Wisconsin River was classified as being mesotrophic.
Station 2
Station two on he Fox and Wisconsin Rivers, for most of the summer,
appear to be similar in terms of phytoplankton productivity. In June and
July, both rivers supported approximatley the same concentration of
phytoplankton. The Fox River supported 5253 cells/ml in June and 2940
cells/ml in July compared to the Wisconsin River which supported 6018 cells/ml
in June and 3830 cells/ml in July. In August, however, the Wisconsin River
supported a considerably greater phytoplankton population (9560 cells/ml)
compared to that in the Fox River (2729 cells/ml).
A similarity, during June and July, between Station two on the Fox
and Wisconsin Rivers is further supported by examination of the periphyton
population. Both stations supported approximately equal numbers of organisms.
The Wisconsin River supported 4928 cells/mm2 compared to 5978 cells/mm2 on
the Fox River.
Fewer macroinertebrate taxa were encountered on the Fox River, Station
two (average of 23 taxa in the qualitative samples) as compared to the same
station on the Wisconsin River (29 taxa in the qualitative samples). As the
19
-------
summer progressed, the biological quality of the benthis community on the
Fox River at Station two deteriorated toward a greater, number of pollution
tolerant forms, while the Wisconsin River remained relatively constant.
The overall condition of Station two was considered to be eutrophic
to mesotrophic for the Fox River and mesotrophic for the Wisconsin River.
Station 3
In June and July, the Wisconsin River supported a considerably greater
pollution enriched biological community than the Fox River. This is
substantiated by the fact that the phytoplankton population in the Wisconsin
River in June reached 9A85 cells/ml compared to only 2907 cells/ml in the
Fox River. Chlorophyll ji concentrations in the Wisconsin River (23.1 vg/1)
and the Fox River (9.1 vg/1) also supported this evidence. The Wisconsin
River also supported a much greater zooplankton population (98 org/1) than
the Fox River (19 org/1). In July, the phytoplankton and chlorophyll ji
also showed greater biological productivity in the Wisconsin River, while
both rivers supported similar zooplankton populations.
