Bear River Watershed
Sierra Nevada, California



Bear River Mercury Cycling Project


In cooperation with the California State Water Resources Control Board, the USGS investigated mercury transport, methylation, and bioaccumulation in the Bear River watershed. Mercury and methylmercury mass balance (inputs vs. outputs) was done for Rollins Lake and Camp Far West Reservoir (CFWR) during 2001-04 and a detailed food web study involving methylmercury bioaccumulation was done for CFWR during 2002-04.
