River and Reservoir Operations Model, Truckee River basin, California and Nevada, 1998
Steven N. Berris, Glen W. Hess, Larry R. Bohman
2001, Water-Resources Investigations Report 2001-4017
The demand for all uses of water in the Truckee River Basin, California and Nevada, commonly is greater than can be supplied. Storage reservoirs in the system have a maximum effective total capacity equivalent to less than two years of average river flows, so longer-term droughts can result in substantial...

Relations among rainstorm runoff, streamflow, pH, and metal concentrations, Summitville Mine area, upper Alamosa River basin, southwest Colorado, 1995-97
Michael G. Rupert
2001, Water-Resources Investigations Report 2001-4027
The upper Alamosa River Basin contains areas that are geochemically altered and have associated secondary sulfide mineralization. Occurring with this sulfide mineralization are copper, gold, and silver deposits that have been mined since the 1870's. Weathering of areas with sulfide mineralization produces runoff with anomalously low pH and high metal...
