Hydrologic factors affecting lake-level fluctuations in Big Marine Lake, Washington County, Minnesota Hydrologic factors affecting lake-level fluctuations in Big Marine Lake, Washington County, Minnesota
A study by the U.S. Geological Survey from 1981 through 1984, in cooperation with the Carnelian-Marine Watershed District and the Minnesota Department of Natural Resources, investigated the causes of large lake-level fluctuations at Big Marine Lake. Historic records document that Big Marine Lake has changed substantially in surface area during the period 1847 through 1983; the maximum...

Runoff and chemical loading in small watersheds in the Twin Cities Metropolitan Area, Minnesota Runoff and chemical loading in small watersheds in the Twin Cities Metropolitan Area, Minnesota
Flow, rainfall, and water-quality data were collected during 1980 for 15 to 30 rainfall and snowmelt events on 6 rural and 11 urban watersheds in the Twin Cities Metropolitan Area. Event or daily flow and load models (for seven constituents) were developed and used with runoff and rainfall data for 1963-80 to compute 2-year frequency annual and seasonal flows and loads for each watershed...

New approach to calibrating bed load samplers New approach to calibrating bed load samplers
Cyclic variations in bed load discharge at a point, which are an inherent part of the process of bed load movement, complicate calibration of bed load samplers and preclude the use of average rates to define sampling efficiencies. Calibration curves, rather than efficiencies, are derived by two independent methods using data collected with prototype versions of the Helley‐Smith sampler...

Artificial infestation of largemouth bass and walleye with glochidia of Lampsilis ventricosa (Pelecypoda: Unionidae) Artificial infestation of largemouth bass and walleye with glochidia of Lampsilis ventricosa (Pelecypoda: Unionidae)
The unionid mussel Lampsilis ventricosa is a bundant in the upper Mississippi River and provides a model for studies related to recovery of the endangered Higgins' eye mussel (Lampsilis higginsi). We tested the suitability of two species of fish species as hosts for glochidia of L. ventricosa. Laboratory-reared largemouth bass (Micropterus salmoides) and walleyes (Stizostedion vitreum)...

Nitrosative elimination of terpenyl alkanolamines leading to alkynyl N-nitroso-analogues Nitrosative elimination of terpenyl alkanolamines leading to alkynyl N-nitroso-analogues
Treatment of selected terpenyl alkanolamines containing isopropylidene moieties with an excess of sodium nitrite in aqueous acetic acid affords the corresponding ethylidyne N-nitrosamines.

Observations on twinning in the sea lamprey (Petromyzon marinus) in the laboratory Observations on twinning in the sea lamprey (Petromyzon marinus) in the laboratory
Forty-five sets of separate, normal twins were produced from four portions of the eggs from one female sea lamprey (Petromyzon marinus) each fertilized by a different male. The percentage of twinning in the different groups of embryos ranged from 1.0 to 1.7. Although the development of some of the twins was slightly slower than average, that of most was within the normal range for sea...

Effects of contaminants on toxicity of the lampricides TFM and Bayer 73 to three species of fish Effects of contaminants on toxicity of the lampricides TFM and Bayer 73 to three species of fish
Waters in the Great Lakes basin contain more than 400 contaminant chemicals that potentially affect fishery resources, commerce, and human inhabitants. We determined in the laboratory the effects of selected contaminants on the toxicity of the widely used lampricides TFM (3-trifluoromethyl-4-nitrophenol) and Bayer 73 (2′,5-dichloro-4′-nitrosalicylanilide) to three species of fish—rainbow...

Distribution and food habits of young-of-the-year fishes in a backwater lake of the upper Mississippi River Distribution and food habits of young-of-the-year fishes in a backwater lake of the upper Mississippi River
The distribution patterns and food habits of young-of-the-year (YOY) fishes in a lentic area adjacent to the main channel of Pool 7 of the upper Mississippi River were studied. Habitats sampled grouped distinctly based on percent composition and abundance of YOY fishes with those having submergent vegetation dominated by a number of important sport species. In late spring, the grouping...

Relationship of young-of-the-year northern pike to aquatic vegetation types in backwaters of the upper Mississippi River Relationship of young-of-the-year northern pike to aquatic vegetation types in backwaters of the upper Mississippi River
The association of young-of-the-year northern pike (Esox lucius) with different aquatic plant types (e.g., submerged, emergent, floating) was studied to evaluate the impacts of a potential loss of backwaters on available fish nursery habitats in the upper Mississippi River. Eight biweekly collections were made at each of six representative lentic habitats in Navigation Pool 7. In the...
