The Mission of the Contra Costa Resource Conservation District is to Facilitate Conservation and Stewardship of the Natural Resources in Contra Costa County.
Peyton Slough WATERSHED
The Peyton Slough watershed is composed of urban Peyton Creek and some minor tributaries, managed runoff from the Shell Oil Refinery located west of I-680, urban runoff from the relatively small Arthur Road neighborhood east of I-680, as well as drainage from portions of I-680 itself. The watershed includes Martinez Reservoir, the terminal reservoir of the Contra Costa Canal. Martinez Reservoir has a spillway connected to Peyton Creek. Peyton Creek is a highly modified urban creek with a combination of open concrete channels, natural channels, and a 1,000-foot long underground concrete culvert through the Shell Oil Refinery property. Peyton Creek is an intermittent stream, mostly drying up by the summer.
