Summary

The Cache Creek Settling Basin (CCSB) is a 13.3 km2 levee-bounded sediment retention basin located at the modern terminus of Cache Creek near the eastern boundary of Yolo County, approximately two miles NE of Woodland, California. The Cache Creek Settling Basin was constructed in 1937 by the U.S. Army Corps of Engineers to trap suspended sediment from the upper Cache Creek watershed during high-flow events, with the purpose of preserving the floodway capacity of the Yolo Bypass, a larger leveed floodway located downstream. This dataset includes subsamples from sediment cores and shallow streambank sediment collected from the Sacramento River watershed. Sediment cores were collected in the Cache Creek Settling Basin during October 2011 [...]

Purpose

Wetland-like environments such as the Cache Creek Settling Basin can be highly active zones for the conversion of inorganic divalent mercury (Hg(II)) to the more toxic methylated form. Ongoing research is increasing the understanding of mercury cycling by identifying specific speciation processes that contribute to methylation within the Cache Creek Settling Basin. Chemical and physical characterization of the Cache Creek sediment core data may reveal downcore variations that signify changes in sediment source or supply and reveal key tracers or fingerprints that can be used to establish spatial linkages to contemporary sediment and catchments, which may be useful in examining spatial and temporal variations in methylmercury in surface sediment within the Cache Creek Settling Basin.
