This report presents low-flow characteristics at six sites on streams in the Eau Claire River basin near Antigo, Wis., where applications for irrigation permits were made. The low-flow characteristics presented are the annual minimum 7-day mean flows at the 2-year recurrence interval and 10-year recurrence interval. A seepage run made October 10, 1974, showed a substantial gain in...

This report presents the results of a flood-plain study of approximately 1.9 mi (3.1 km) of the South Branch Shiawassee River in Livingston County. This reach of stream s in a currently unincorporated area about 40 mi (64 km) northwest of Detroit. Although little development has taken place, the potential for development is great due to urban spread from the Detroit Metropolitan area. To...

Study of the residue dynamics of 2-methylquinoline (quinaldine) and 3-trifluoromethyl-4-nitrophenol (TFM) in rainbow trout yielded the following findings: 1. Uptake and distribution of TFM by trout was influenced by the biotransformation of the lipidsoluble free phenol. No such effect was observed with quinaldine. 2. Disappearance of quinaldine and TFM from gallbladder bile was slower...

A variety of glacial landforms (moraines, till plains, drumlin fields and outwash plains) characterized the 3,890-square mile Mississippi and Sauk Rivers watershed. Underlying the glacial drift are Cambrian and Precambrian sedimentary rocks in the southeastern part of the watershed and Precambrian igneous and metamorphic rocks elsewhere. Surface drainage is entirely to the Mississippi...

On April 18 between 5 p.m. and 12 p.m. the city of Williamston experienced an intense rain storm that caused the Red Cedar River and the many small streams in the area to overflow their banks and resulted in the most devastating flood since at least 1904. Local officials estimated a loss of \$775,000 in property damage. Damage from flooding by the Red Cedar River was caused primarily by...

Runoff is the water in a river or stream that results from precipitation falling on the drainage basin. It is the net discharge into the stream from surface-water and ground-water sources with losses occurring from evapotranspiration and other consumptive uses. Runoff can be expressed by a variety of numerical values, but average depth of water over the drainage basin, in inches per year...

This hydrologic atlas represents a part of a comprehensive study of the water resources of southeastern Michigan. Its purpose is the provide information on (1) the physical features of basins for minor streams draining into St. Clair River, Lake St. Clair, Detroit River, and Lake Erie, (2) the characteristics of streamflow, (3) the quality of surface water and ground water, and (4) the

-p^e need for study of lake-ground-water interchange has been accentuated by eutrophication of lakes in the Pearl-Sallie Lakes area of west-central Minnesota. The local ground-water flow system is dominated by an outwash aquifer that is sandwiched between two till layers in the western part of the area and exposed at the land surface in the eastern part. Ground water discharges from the...

Selected physical, chemical, and biological parameters were determined to assess the quality of 20 lakes in the cities of Eagan and Apple Valley, Minn. All the lakes are eutrophic except Holland and Fish Lakes, which are mesotrophic. Some lakes (including Fish Lake) have storm sewer inlets but are not discernibly different in quality than lakes with no such inlets.

A water-quality assessment of the Burnham Creek watershed, Polk County, Minn., was made in May 1975. Surface waters were calcium magnesium bicarbonate types with 0.11 mg/liter or less of nitrite plus nitrate nitrogen and 0.10 mg/liter or less of total phosphorous. Fecal coliform bacteria concentrations were between 3 and 720 colonies per 100 milliliters and fecal Streptococci...
