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...

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...

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...

Rock County is in south-central Wisconsin adjacent to the Illinois State line. The county has an area of about 723 square miles and had a population of about 113,000 in 1957 ; it is one of the leading agricultural and industrial counties in the State. The total annual precipitation averages about 32 inches, and the mean annual temperature is about 48 ? F. Land-surface altitudes are...

Waupaca County is in east-central Wisconsin. No serious ground-water problems existed in 1960 except in a few localities where crystalline rock is near land surface or is covered by nearly impermeable till. The use of ground water for irrigation has not appreciably affected ground-water levels. The county is covered by Pleistocene till, glaciolacustrine (lake), glaciofluvial (stream)...

The Green Bay area, which includes parts of Brown, Outagamie, and Shawano Counties, has an area of about 525 square miles in eastern Wisconsin at the south end of Green Bay. In 1960, it had a population estimated at 124,000; Green Bay, the largest city in the area, had a population of 62,888. The Green Bay area is underlain by a basement complex of crystalline rocks of Precambrian age...
