Residues of the 2-aminoethanol salt of 2',5-dichloro-4'-nitrosalicylanilide (Bayer 73), as determined by gas-liquid chromatography, were rapidly accumulated by fish exposed to the lampricide -in blood plasma, gallbladder bile, and muscle tissue of coho salmon (Oncorhynchus kisutch) and rainbow trout (Salmo gairdneri), and in bile and muscle of channel catfish (Ictalurus punctatus) and largemouth b

Ground-water resources of Marquette County are about evenly divided between bedrock aquifers and aquifers in glacial deposits. In the northern and the extreme southern parts of the county, most wells are completed in bedrock at depths less than 100 feet. In the central part, most wells are completed in glacial deposits; some of these wells are as deep as 200 feet. Yields, in some places as high as

Tracing of rhodamine WT dye has provided time-of-travel data for waste-load allocation studies of a 42.8-mile reach of the Flint River at low flow. A discharge equaled or exceeded about 90 percent of the time was measured at Grand Traverse Street in Flint before dye injection. Dye was injected at two locations in Flint--at Utah Dam and at Grand Traverse Street, From Utah Dam to Grand Traverse Stre

Rotenone, antimycin, permethrin, pydrin, and Salicylanilide I were tested for their toxicities against fathead minnows (Pimephales promelas) in the presence of Canadian waterweed (Elodea canadensis) or suspended clay. The plants had little effect on the activity of rotenone and antimycin but substantially reduced the activity of permethrin and pydrin (synthetic pyrethroids). Bentonite severely inh

Growth and condition of bluegills epomis macrochirusfrom five acidic lakes (pH 5.1-6.0) and six circumneutral lakes (pH 6.7-7.5) in northern Wisconsin were compared. Although mean condition factors and mean back-calculated total lengths at ages 1 to 4 varied significantly among lakes, the differences were not related to lake pH. Rather, the ranks of mean condition factors and back-calculated le

Water resources data for the 1981 water year for Michigan consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water temperature of ground water. This report contains discharge records for 178 gaging stations; stage only records for 4 gaging stations; stage and contents for 5 lakes and reservoirs; wat

Quality of water in the Ironton-Galesville aquifer is generally acceptable for all kinds of uses. Calcium magnesium bicarbonate type water is most common. The dissolved-solids concentration ranges from about 200 to 1,000 milligrams per liter. The lowest values are in the northern part of the aquifer, where the bedrock is at or close to land surface, and the lowest ones are in the southwestern part
