Abstract |
Water quality along the Truckee River between Lakes Tahoe and Pyramid in northeast California and northwest Nevada was investigated. The six major sampling sites defined five major watersheds along the Truckee River between the outlet dam at Lake Tahoe and the inlet to Pyramid Lake at Nixon. Each watershed was characterized by: area; percentage area logged from 1959 through 1968; percentage area burned from 1959 through 1968; percentage area covered by paved and dirt roads; soil-type percentage for each of eight types common to the area; and vegetation or land-use percentage for each of twelve kinds found in the entire Truckee Watershed. Results of chemical analyses for nitrate and organic nitrogen, phosphate, and boron are tabulated. The overall levels of nitrogen and phosphate are comparatively low from Tahoe Dam to Boynton Lake (just above the Sewage Treatment Plant at Reno). The levels fluctuate around that separating oligotrophic and eutropic conditions, commonly taken as 0.1 mg/liter for nitrogen and 0.01 mg/liter for phosphate. Boron concentrations ranged from .03 mg/liter below verdi to 3.18 mg/liter at Steamboat above Sewage Treatment Plant. (WRSIC abstract) |
