Cache Creek



Lower Cache Creek and Settling Basin

The USGS has been involved for several years in studies related to mercury contamination in the lower Cache Creek watershed and the Cache Creek Settling Basin, which traps sediment that otherwise would flow into the Yolo Bypass. During 2001-02, the USGS did studies of mercury and methylmercury loads as part of a larger multi-investigator study sponsored by the California Bay-Delta Authority (CALFED). During 2005-06, the USGS investigated sediment chemistry and water quality in seasonal and permanent wetlands in the Cache Creek Settling Basin and the adjacent Yolo Bypass in cooperation with Sacramento River Watershed Program, the Sacramento Regional County Sanitation District, and the U.S. Environmental Protection Agency. Starting in 2009, the USGS California Water Science Center has been investigating mercury and methylmercury loads into and out of the Cache Creek Settling Basin, in cooperation with the California Department of Water Resources.
