Muskegon County, Michigan, disposes of wastewater by spray irrigating farmland on its waste-disposal site. Buried drains in the highly permeable unconfined aquifer at the site control the level of the water table. Hydraulic conductivity of the aquifer and drain-leakance, the reciprocal of resistance to flow into the drains, was determined at a representative irrigation circle while...

Low-flow characteristics of streams in the St. Croix River basin , Wisconsin, are presented. Included are estimates of low-flow frequency and flow duration at 7 gaging stations, low-flow frequency characteristics at 23 low-flow partial-record stations and 78 miscellaneous sites, and a list of base-flow discharge measurements at 29 miscellaneous sites. Equations are provided to estimate...

The purpose of this 5-year study is to (1) evaluate the sediment transport, streamflow characteristics, and stream-channel morphology, (2) relate the above to land-use practices; and (3) evaluate the effect that changes in land-use practices will have on Pheasant Branch basin near Middleton, Wis. This report presents findings of sediment transport, streamflow characteristics, and stream...

Four modified nonradioactive-tracer methods and 20 predictive equations for determination of stream-reaeration coefficients in three small Wisconsin streams were compared with the radioactive-tracer method developed by Tsivoglou. Of the four modified-tracer techniques, the propane-area technique, which measures the total weight of propane gas passing stream-sampling stations, yielded the...

Data were collected on the hydrology of the Copper-Nickel study region to identify the location and nature of groundwater resources, determine the flow characteristics and general quality of the major streams, and determine the potential effects of mining copper and nickel on the hydrologic stream. Groundwater generally occurs in local flow systems within surficial deposits and in...

Low-flow characteristics in the Red Cedar River basin, Wis., where surplus water may be diverted, and methods to determine low-flow characteristics at additional sites are presented. The low-flow characteristics were determined by various methods at 71 sites. For the three gaging stations in the basin, frequency analysis was used to determine the low-flow characteristics. At 17 partial...

The St. Louis River is the largest tributary to Lake Superior in Minnesota. It drains a predominantly forested area of about 3,650 mi2 (Minnesota Department of Conservation, 1959) and discharges into the lake at Duluth. The Mesabi Iron Range, noted for rich deposits of iron ore, parallels much of the northern watershed boundary. Large areas of land were altered by mining activities, as...
