Selected biological characteristics of streams in the southeastern Uinta Basin, Utah and Colorado
Ronald W. Naten, Richard H. Fuller
1981, Open-File Report 81-644
Biological sampling was carried out during 1976-78 in five streams in the southeastern Uinta Basin, Utah and Colorado, in order to provide baseline water-quality data for an area of potential oil-shale development. The biological activity in the streams sampled generally is limited by physical factors more so than by chemical...

Ground-water reconnaissance of part of the lower Kenai Peninsula, Alaska
G.L. Nelson, P.R. Johnson
1981, Open-File Report 81-905
Most residential and industrial development of the Lower Kenai Peninsula, Alaska, is along the coast of Cook Inlet. Most of the information about subsurface conditions is obtained from wells along the coast. Ground water is recharged by local precipitation, and slow drainage of ground water to the streams maintains streamflow...
