By Gregory A. Payne
ABSTRACT
Long Meadow Lake, Black Dog Creek, and Ponds AP-9 and AP-10
which lie in an area designated for a trunk highway bridge crossing
the Minnesota River, were sampled for baseline water quality prior
to construction of the bridge. Data collected show that dissolved-
solids fluctuate seasonally. Dissolved oxygen:/ranged from less
than 1 milligram per liter under an ice cover to 13-9 milligrams
per liter in the September sample at site 4 in Long Meadow Lake.
The phytoplankton analyses showed pulses in algae populations,
blue-green algae being the dominant type in at least one sample
from each of the water courses.
INTRODUCTION
Purpose
Long Meadow Lake, Ponds AP-9 and AP-10, and Black Dog Creek
are located in Hennepin and Dakota Counties in southeastern Minnesota
(fig. 1). These water courses lie in an area designated for construc
tion of the Cedar Avenue South (Trunk Highway 36) bridge crossing
the Minnesota River.
The purpose of study was to define the current chemical and
biological quality of Long Meadow Lake, Ponds AP-9 and AP-10, and
Black Dog Creek. Data collected during and after bridge construction

will be compared with those presented in this report to de ?mine
the effects of construction on water quality. The study w made
by the U.S. Geological Survey in cooperation with the Minru ota
Department of Transportation.
Geographic Setting
Topographic relief is about 350 feet, ranging from less than
700 feet above sea level along the flood plain of the Minnesota River
to about 1,050 feet atop the morainic hills in the southeastern
part of the area.
Black Dog Creek and Long Meadow Lake lie in the flood plain of
the Minnesota River. Formation of leveelike deposits along the river
during floods prevented drainage of the flood plain, thereby forming
the lake.
Ponds AP-9 and AP-10 are in the end moraine formed at the south
limit of the Superior and Rainy lobes of Wisconsin glaciation. The
moraine is characterized by knob and kettle topography, with small
ponds occupying many of the kettles.
Hydrologic Setting
Long Meadow Lake, Pond AP-9 and Pond AP-10 are shallow and
have littoral zones that extend across their entire basins. Water
levels of Long Meadow Lake and Ponds AP-9 and AP-10 fluctuate sea
sonally, but depths were generally less than 4 feet. Emergent vegeta
tion essentially divides Long Meadow Lake into several small open-
water areas.
Long Meadow Lake receives inflow from springs and storm water.
At high stages the Minnesota River overflows into the lake. Water
discharges through an. outlet at its eastern lobe.
3
Ponds AP-9 and AP-10 receive overland runoff but have no outlets.
Black Dog Creek receives water directly from Black Dog Lake and
indirectly"from the Minnesota River. Minnesota River water is pumped
into Black Dog Lake by a nearby electrical generating plant (fig. 1).
Eleven discharge measurements (table 2) were made on the creek during
this study. Measured discharges ranged from 1.5 cubic feet per second
to 37 cubic feet per second.
Scope
Long Meadow Lake was sampled near the surface at the five sites
shown in figure 1. Each site was visited four'times: summer, late
fall, before spring breakup, and after spring breakup. Sites 3> ^>
and 5 were omitted from the fourth sampling because of low water
levels.
Ponds AP-9 and AP-10 were sampled near the surface three times;
summer, late fall, and winter. Black Dog Creek was sampled monthly
from August 1975 to June 1976.
Field determinations included pH, specific conductance, DO
(dissolved oxygen), water temperature, fecal coliform and fecal
Streptococci, bacteria, and air temperature.
Concentrations for the nitrogen series, phosphorous, alkalinity,
calcium, silica, sodium, chloride, TOC (total organic carbon), turbidity,
oil and grease, and dissolved and suspended solids were determined in
the laboratory.
Phytoplankton samples were collected and analyzed in the laboratory
for codominant genera and cell density.
Bottom material was sampled at each site during the late fall and
analyzed for organic carbon, nitrogen, phosphorous, oil and grease,
aluminum, arsenic, cadmium, chromium, copper, Mead, mercury, and zinc.
METHODS
Samples for physical and chemical parameters were collected and
determined by methods reported~lrf~Brown and others (1970) and Goerlitz
and Brown (1972). DO concentration was determined by using a DO meter
and the percent DO saturation for elevation and water temperature cal
culated as described in American Public Health Association, and others
(1971, p. 480).
Fecal coliform and fecal Streptococci were determined by the mem
brane filter technique described by Slack and others (1973). Phyto-
plankton concentrations were determined by methods described by Slack
and others (1973).
DATA RESULTS
Physical and Chemical Characteristics
The results of the field and laboratory determinations are shown
in tables 1-3- In addition, selected characteristics have been presented
graphically (figs. 2-6).
Concentrations of several constituents were found to be variable.
For example, dissolved-solids concentrations in Long Meadow Lake
fluctuates with respect to site and season, as shown in figure 2.
Dissolved-solids concentrations and water discharge in Black Dog
Creek are shown in figure 3- It is likely that data from Black Dog
Creek reflects water quality in Black Dog Lake, which is affected by
water pumped from the Minnesota River.
The water courses sampled in this study are primarily of the
calcium bicarbonate type, although sodium and chloride and major
constituents in some samples. The fluctuating chloride concentrations
in Long Meadow Lake and Black Dog Creek (fig. 4) suggest

influence from urban runoff.
The water concentrations of phosphorous were highest in late
winter in Long Meadow Lake and Pond AP-9 Phosphorous concentrations
were highest in late summer in Pond AP-10. Total phosphorous concen
trations in Black Dog Creek are shown in figure 5. Total and dissolved
phosphorous concentrations increased significantly during a high
discharge period in Black Dog Creek in June.
DO concentrations for a particular water body will vary daily as
well as seasonally because of factors such as water temperature,
photosynthetic activity, and oxygen consumption. The percent DO
saturation is, therefore, often more useful than the DO concentration
when comparing oxygen levels over a period of time.
Table 1 shows that DO levels in Long Meadow Lake are high in late
summer (Sept. 17), lower in late fall (Dec. 2), and much lower in late
winter (March 10). DO saturation values above 100 percent, found in
Long Meadow Lake in late summer, are probably due to a high level of
photosynthesis. The low value at site 5 on September 17 was probably -
caused by a dense surface accumulation of floating aquatic plants.
Shading from these plants limit light penetration, thereby reducing
oxygen production by photosynthesis. Restricted oxygen production,
in combination with continuous plant respiration, probably caused
the lower value at site 5» The March DO values for Long Meadow Lake
were much lower than those in previous samples. Reduction of photo
synthesis due to snow and ice cover, chemical and biological oxidation,
and reduced reaeration because of ice cover are all probable contrib
uting factors to the low values.
Black Dog Creek and Pond AP-9 retained high DO even in late winter
In contrast, Pond AP-10 had low DO, even in late summer. In highly
10
productive lakes, low pH and DO follow massive algal blooms (Hutchinson,
1957, p. 599). Thus, the low observed DO, may have been caused by
decompositon. ,of organic material.
. The pH values for most of the sites were highest in the late
summer samplings, except in Pond AP-10 (tables 1-3). High pH values
may be associated with photosynthesis. Algae remove carbon dioxide
from solution and convert it into cellular material. The carbonate
equilibrium, as it exists in natural waters, is affected in that the
carbonate concentration and pH may increase (Symons and others, 1964,
p. 18). The decline in pH during late fall and winter can probably
be attributed to oxidation of organic material and release of carbon
dioxide combined with a decline in photosynthesis.
Samples of bottom material were obtained at each of the sites
during the late fall sampling period (tables 4-6). Concentrations of
the bottom material constituents generally were highest in the Long
Meadow Lake sites. Ponds AP-9 and AP-10 had lower values for most
constituents. For example, oil and grease concentrations were much
higher in the bottom sediments of Long Meadow Lake and Black Dog Creek,
ranging from 2,100 to 3 3 000 milligrams per kilogram compared with only
2 to 3 milligrams per kilogram in Pond AP-9 and AP-10.
Biological Characteristics
The results of the phytoplankton and bacteria analyses for all
sites are listed in tables 7-10. All sites had blue-green algae as
the dominant type in at least one of the samplings.
In long Meadow Lake the species compositon varied between sites.
At th'e time of the September sampling, sites 3 and 4 were dominated .
by blue-green algae, site 2 by diatoms, site 1 about equally by blue-greens
and diatoms, and site 5 by diatoms and flagellates. At the time of
11
the December sampling, diatoms and blue-greens were less abundant,
with flagellates and green algae becoming more dominant.
Pulses on variations in algal populations, particularly blue-
greens and diatoms, have been reported for many lakes. The pulses
seem to be caused by complex interactions'among temperature, nutrient
supply, and reproductive potential of the plants. .The composition
of phytoplankton communities vary greatly from one water body to another,
and no truly typical community exists (Ried, 1961, p. 29*0. This
is apparent in this study, as Pond AP-9 was dominated by green algae
and flagellates on September 19, while Pond AP-10 was dominated by
blue-greens on the same day.
On September 19 the cell count in Pond AP-9 was 3»800 cells per
milliliter. The several species present represented three groups '
diatoms, green algae, and flagellates. By November 20 the cell count
increased to 32,000 cells per milliter, and 99 percent of the cells
were a blue-green type, represented by a single genus Anacystis. -.
By March 3 the cell count remained nearly as high, at 30,000 cells
per milliter, but several species were present and t'he flagellate
type was dominant. Pond AP-10 and Black Dog Creek also show pulses
in cell counts and variation in dominant groups between samplings.
Black Dog Creek, however, shows a trend toward lower cell counts
in winter, having diatoms as the dominant type (fig. 6).

Concentrations of dissolved-solids fluctuated seasonally and
between sampling sites in Long Meadow Lake. Both Long Meadow Lake
and Black Dog Creek had higher dissolved-solids than Ponds AP-9
and AP-10. Chlorides were a part of the chemistry of all the waters
but to a much lesser extent in Pond AP-10. In contrast, Pond AP-10
had much higher nitrogen and phosphorous concentrations. Total
and dissolved phosphorous and nitrogen, as well as dissolved solids
were at maximum levels during the period of highest flow in Black
Dog Creek.
Low DO was charasteristic of Long Meadow Lake and AP-10 under
ice cover in late winter, but not of Black Dog Creek and Pond AP-9.
Pulses of algae populations were characteristic of all the
water courses, and blue-green algae dominated at least one sampling
period at all sites.
Additional comparative interpretations can be made when data
from later sampling, during and after construction, are available.
