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.

Page 9: LONG MEADOW LAKE, PONDS AP-9 AND AP-10 AND BLACK DOG … · 2011-08-23 · Long Meadow Lake, Pond AP-9 and Pond AP-10 are shallow and have littoral zones that extend across their

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

Page 16: LONG MEADOW LAKE, PONDS AP-9 AND AP-10 AND BLACK DOG … · 2011-08-23 · Long Meadow Lake, Pond AP-9 and Pond AP-10 are shallow and have littoral zones that extend across their

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

Page 17: LONG MEADOW LAKE, PONDS AP-9 AND AP-10 AND BLACK DOG … · 2011-08-23 · Long Meadow Lake, Pond AP-9 and Pond AP-10 are shallow and have littoral zones that extend across their

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).

SUMMARY

This report presents physical, chemical, and biological data

collected from Long Meadow Lake, Black Dog Creek, and Ponds AP-9

and AP-10.

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.
