A broad-perspective analysis of the ground-water resources and present and possible future water development and management in the Souris-Red-Rainy Region is presented. The region includes the basins of the Souris River within Montana and North Dakota; the Red River of the North in South Dakota, North Dakota, and Minnesota; and the Rainy River within Minnesota. The region includes 59,645...

Low-flow characteristics of streams in the lower Wisconsin River basin are presented. Included are estimates of low-flow frequency and flow duration at 11 gaging stations; low-flow frequency characteristics at 26 low-flow partial-record stations and 70 miscellaneous sites; and a list of low-flow discharge measurements at 155 miscellaneous sites where insufficient data were available to...

The water supply for the city of Madison, Wisconsin, and for surrounding municipalities is obtained from the ground-water reservoir that underlies the area. This ground-water reservoir is composed of an upper aquifer and an underlying sandstone aquifer. High-capacity water-supply wells pump from the sandstone aquifer. Pumping from the sandstone aquifer has resulted in hydrologic changes...

Six lakes in the headwaters of Ely Creek form the Lake Sally system. This system is the source of water for Ishpeming and several small communities in the central part of Michigan's Upper Peninsula. During years of average precipitation, more water is used from the system than is supplied to it, and the quantity of water in lake storage is depleted. Below-normal precipitation in 1976 and...

The radioactive and modified tracer techniques were used to measure the reaeration coefficients of two reaches each of Black Earth Creek and the Madison Effluent Channel near Madison, Wis. Comparison of the results showed that coefficients measured with the modified technique ranged from -8.96 to +3.61 and from +15.7 to +32.2 percent different from the coefficient measured with the...

A digital model was developed to study the impact on ground-water conditions of the Muskegon County wastewater disposal system. At the disposal site, wastewater is stored in two 850-acre (344-ha) lagoons and then spray-irrigated on crop land. About 70 miles (105 km) of drainage tile, which underlies the irrigated land, has caused the water table to be lowered substantially. The decline...

The 120-acre Nevin wetland at the south edge of Madison, Wis., is a discharge area of the local ground-water system. A hydrologic unit composed of drift and the upper part of an underlying sandstone sequence provides ground-water inflow. Ground water enters as springflow and as leakage upward through the organic wetland soils. The average annual water budget for the wetland was based on...

Communities that use fill-and-draw waste-water treatment lagoons or waste-stabilization ponds are required to discharge during the spring and fall of the year at a rate that does not exceed the assimilative capacity of the receiving stream. The 10-year low mean monthly discharge (MMQ10) for October, November, April, and May for the receiving stream has been used to establish the...

The Copper-Nickel study region lies in the Superior Upland physiographic province and is located approximately 60 miles north of Duluth and 100 miles southeast of International Falls, Minnesota. It straddles the Laurentian Divide, which separates Hudson Bay and Lake Superior drainage. The topography exhibits a southwesterly trending lineation that parallels the strike of southeastward...

A map (scale 1:100,000) of the water table in Racine County in southeastern Wisconsin was prepared using water levels from more than 250 wells. The work was done as a cooperative project between the U.S. Geological Survey and the Southeastern Wisconsin Regional Planning Commission. The map shows the altitude of the water table in increments of 20 feet, with supplemental 10-foot contours...
