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.
