The purpose of the ground-water investigation of Dane County, Wis., was to determine the occurrence, movement, quantity, quality, and availability of ground water in the unconsolidated deposits and the underlying bedrock. The relationships between ground water and surface water were studied in general in Dane County and in detail in the Madison metropolitan area. An analysis was made of...

Abundant ground water for irrigation is available in the outwash deposits in western Waushara County, and many more large-capacity wells can be developed in these deposits without seriously lowering the water level. Pumping for irrigation temporarily lowers water levels in the vicinity of the wells but has not lowered regional water levels. Pumpage has probably intercepted and utilized...

Additional supplies of water are available near the municipalities on the east-central Mesabi Iron Range. Both ground water and surface water offer good potential supplies. For the ground-water supplies, the most productive aquifers are the Biwabik Iron Formation and the stratified glacial drift. Surface-water supplies are variable. Streams in the western part of the report area are too...

In this atlas, mineralized ground water is viewed presently as a source of water in some areas, but in much of the country as a source for future development. Mineralized water underlies large areas of the country, and its importance will grow as present supplies of fresh water are appropriated and developed. The potential uses fall in two main categories: (1) direct use in industrial...

Portage County has abundant resources of generally good quality water and, although water problems exist locally, depletion or general scarcity of water is not likely in the foreseeable future. The county receives annually about 31 inches of precipitation, of which about 21 inches is lost as evaportranspiration. The average annual water yield is about 10.6 inches and consists of about 10...

Additional supplies of water are available near the municipalities on the western Mesabi Iron Range. Potential yields from both ground-water and surface-water sources are good. The most productive aquifers for ground-water supplies are the Biwabik Iron-Formation and the stratified glacial drift. Areas of stratified drift believed to have good water potential have been outlined. The most...

Additional supplies of water are available near the municipalities on the eastern Mesabi Iron Range and the Vermilion Iron Range. On the eastern Mesabi Range the potential for additional development of both ground-water and surface-water supplies are good, and on the Vermilion Range the best potential for development is from surface-water resources. The most productive aquifers in the...

Artesian water pressure in the deep sandstone aquifer continued to decline throughout most of the Milwaukee-Waukesha area, Wisconsin between 1950 and 1961. Areas of greatest water-level decline were in northeast Waukesha County and in northwest Milwaukee County. The chief cause of the decline was continued heavy pumpage. The major aquifers of southeastern Wisconsin are the Niagara...

Melt-water channel deposits are among the most important aquifers in southwestern Minnesota, but permeable zones within the deposits are difficult to locate. Interpretation of the depositional history of proglacial channel deposits from aerial photographs and test-hole samples indicates the position of the permeable zones. Generally, the coarse-grained deposits are in headwater areas...
