Availability of supplemental water supplies at salmonid fish-propagation stations in Wisconsin

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. 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).

Nitrogen in water in Nassau and Suffolk counties, Long Island, New York, in 1971

The concentration of inorganic nitrogen was measured in samples from 521 wells in the upper glacial and Magothy aquifers and from 46 streams in Nassau and Suffolk Counties during May 1971. The predominant form of dissolved nitrogen was nitrate. Nitrate concentrations (as N) in the upper glacial aquifer in both counties ranged from 0 to 20 milligrams per liter (mg/L) ; those in the Magothy aquifer ranged from 0 to 20 mg/L but were generally much lower in Suffolk County than in Nassau County. Nitrate concentrations (as N) decreased with depth in both counties; below 400 feet, concentrations ranged from 0 to 0.2 mg/L. Nitrate concentrations (as N) of streams ranged from 0 to ii mg/L, which is an indication of the general quality of water in much of the upper glacial aquifer, the source of most of the streamflow. Generally, concentrations of total nitrogen in streams draining the sewered area of Nassau County were lower than those in streams draining the unsewered area. Median concentrations of total inorganic nitrogen (as N) were 1.3 mg/L for the sewered area and 7.5 mg/L for the unsewered area. About 5,500 pounds of nitrate (as N) was estimated to be discharged daily in surface flow to tidewater from Nassau and Suffolk Counties.

Summary of water resources of Salt Lake County, Utah

This report is a summary of a comprehensive report on the present water resources of Salt Lake County, Utah, and the potential for additional development The average total annual withdrawals from surface and underground sources during 1964-68 were about 580,000 acre-feet for all uses that deplete the supply, except that used for maintenance of waterfowl-management areas. The withdrawals projected for the year 2020 are 1,200,000 acre-feet. The maximum annual firm supply that can be derived from the sources now available is about 700,000 acre-feet, of which about 200,000 acre-feet would be derived from subsurface sources. Achievement of this annual yield would require nearly complete regulation of streamflow that now is practically unregulated, larger drawdowns of ground-water levels than have been experienced, and overall management of surface and subsurface sources as parts of a single resource.

Water resources of Salt Lake County, Utah

This report is the eighth in a series prepared by the U. S. Geological Survey in cooperation with the Utah Department of Natural Resources, Division of Water Rights, that describes the water resources of the western basins of Utah. (See fig. 1.) Its purpose is to present available hydrologic data on the Park Valley area, to provide an evaluation of the potential water-resource development of the area, and to identify needed studies that would improve understanding of the area's water supply.
