R.P. Novitzki C. Albert Harr 1979 <p>Supplemental water supplies are available at all the 12 fish-propagation stations. At seven of the stations water may be obtained by diverting or impounding streams. Ground water is available from glacial sand-and-gravel aquifers at all the stations and from sandstone aquifers at 7 of the 12 stations. Probable well yields range from 100 to 1,000 gallons per minute from the sand and gravel and from 50 to 1,000 gallons per minute from the sandstone.</p> <p>The response of pumping 1,600 gallons per minute from a ground-water source at Crystal Springs, Langlade, Nevin, and Osceola was estimated by a digital model. Estimated drawdown after 10 years of pumping ranged from 10 to 28 feet (6 to 35 percent of the saturated thickness of the aquifers).</p> application/pdf 10.3133/ofr791170 en Geological Survey Availability of supplemental water supplies at salmonid fish-propagation stations in Wisconsin reports
