Bioaccumulation of Mercury by Fish and Fish-forage Organisms in Camp Far West Reservoir, Yuba and Placer Counties, California

Mercury contamination from historic gold mining operations is widespread in many rivers, lakes, and reservoirs on the western slopes of the Sierra Nevada. A multidisciplinary investigation by USGS is attempting to better understand mercury dynamics and to identify hot spots within Camp Far West Reservoir in order to determine if remediation More...

Mercury Contamination in Fillets of Selected Sport Fishes from Lake Natoma

Lake Natoma, an 8,760 acre-feet reservoir on the American River, is managed by the U.S. Bureau of Reclamation (USBR) for multiple uses that include fishing and other water-based recreation. Preliminary results from 22 fish samples collected in Lake Natoma during August 2000 indicate that the mercury content may approach or exceed guidelines for More...

Cellular and Genetic Tracers of Transport Time in Groundwater Systems

Artificially maintained water levels within the lake and stresses placed upon the aquifer by well withdrawals facilitate movement of water from the lake into the local ground water system, potentially allowing contaminants to enter the aquifer from the lake. This raises national concern because similar lakeside settings exist throughout the United More...
