The Aurora area is a glaciated upland of drift-mantled slopes, channels, swamps, and glacial-lake plains. It covers about 24 square miles of the eastern part of the Mesabi Iron Range in northeastern Minnesota. A deep narrow channel along the Embarrass River, the principal outlet of a former large glacial lake north of the Embarrass Mountains, lies partly within the area. The deposits in...

This collection of 43 short papers is the first published chapter of 'Geological Survey Research 1966.' The papers report on scientific and economic results of current work by members of the Conservation, Geologic, Topographic, and Water Resources Divisions of the U.S. Geological Survey. Chapter A, to be published later in the year, will present a summary of significant results of work...

The watershed is underlain by water-bearing glacial drift, cretaceous rocks, and Precambrian crystalline rocks. It is an elongate basin 92 miles long and has a drainage area of 977 square miles. The Pomme de Terre River flows within an outwash valley discharging into the Minnesota River at Marsh Lake.

Before December 1958 the treated sewage effluent from the Madison, Wisconsin, metropolitan area was discharged into the Yahara River at the north end of Lake Waubesa, which is upstream from the USGS gaging station on the Yahara River near McFarland, Wis. Since December 1958 the effluent has been diverted southward from the sewage treatment plant into Badfish Creek and enters the lower...

As part of a program for managing its ground-water supply, the city of Kalamazoo has constructed induced-recharge facilities at the sites of several of its well fields. To determine the benefits of induced recharge in a water-management program, the U.S. Geological Survey, in cooperation with the city, conducted a series of field experiments at a city well field (Station 9). The 12...

Within the Mesabi-Vermilion Iron Range area, water of good quality is available from the Biwabik Iron-Formation, from stratified drift, and from lakes and streams. About 700 bgy (billion gallons a year) leaves the area as surface water, of which about one-third comes from ground water. Leached, oxidized, and fractured parts of the Biwabik Iron-Formation yield as much as 1,000 gpm...

Additional supplies of water are available near the municipalities on the central Mesabi Iron Range. Ground water presents the greatest potential yield, and most of the productive aquifers are in the Biwabik Iron-Formation and the stratified glacial drift. /k single body of ice-contact stratified drift underlies parts of all but one of the five municipality areas mapped. Surface-water...

Additional supplies of water are available near the municipalities or the west-central Mesabi Iron Range. The largest sources are the ground-water aquifers in the Biwabik Iron-Formation and the stratified glacial drift. Areas of stratified drift that probably have good water potential have been outlined. Surface-water supplies are negligible in the eastern part of this area but increase...

The Little Plover River basin is in the sand-plain area of central Wisconsin. The basin and the surrounding sand-plain area provide a good fish and wildlife habitat and is a popular locale for sport fishing. Good yields may be obtained in the area from irrigated crops, and the irrigated acreage has been increasing rapidly in recent years. Sportsmen and conservationists are concerned...
