Water Quality
Because of the endangered species present and because the Lake Tahoe Basin comprises the headwaters of the Truckee River, Pyramid Lake has been the focus of several water quality investigations, the most detailed starting in the mid-1980s. Under direction of the U.S. Environmental Protection Agency, a comprehensive dynamic water quality computer model, the DSSAM Model was developed to analyze impacts of a variety of land use and wastewater management decisions throughout the 3,120-square-mile (8,100 km2) Truckee River Basin. Analytes addressed included nitrogen, reactive phosphate, total dissolved solids, dissolved oxygen and nine other parameters. Based upon use of the model, some decisions have been influenced to enhance Pyramid Lake water quality and aid the viability of Pyramid Lake biota.

“It is moot whether there be divinities
As I finish this play by Webster:
The street-cars are still running however
And the katharsis fades in the warm water of a yawn.”

“Liberation is an evershifting horizon, a total ideology that can never fulfill its promises.... It has the therapeutic quality of providing emotionally charged rituals of solidarity in hatred—it is the amphetamine of its believers.”
