Castro Creek is a creek in Richmond, California, in the western part of the city adjacent to the Chevron Oil Refinery. Wildcat Creek drains into it directly and though other Wildcat Marsh tributaries into Castro Cove of San Pablo Bay. The creek drains from the drainage basin of the surrounding area and was once part of the channel that separated the island of Point Richmond with the mainland. [2] The stream is waterway is named after Don Víctor Castro the owner of the area when it was Rancho San Pablo.[ citation needed ] The Chevron Richmond Refinery dumps wastewater into the creek routinely 500 yards north of the confluence with Wildcat Creek and also in a drainage. [3] Other waste may only be dumped into the creek through a drainage ditch on Castro Street during high intensity rainfall. [3] Castro Creek is a fishing, shell-fishing, and recreation area. [3] Its estuarine habitat is essential habitat for several endangered species. [3] The creek is also a fish spawning and migration center. [3] The refinery creates 5.6 million US gallons (21,000 m3) per day of byproduct refinery process water, cooling water, storm water and other wastewater which it discharges into Castro Creek, Castro Cove, Wildcat Marsh, and San Pablo Bay. [3] Castro Cove has become very polluted from 85 years of unbridled discharge of waste waters with PAHs and mercury from the Chevron Oil Refinery and is scheduled to begin cleanup efforts in summer 2007.

Richmond is a city in western Contra Costa County, California, United States. The city was incorporated on August 7, 1905.

Wildcat Marsh is the wetlands delta formed by the mouth of Wildcat Creek at its confluence with Castro Creek in Richmond, California. The marsh is critical habitat for endangered species and has been contaminated and damaged by runoff from the Chevron Richmond Refinery and the city's landfill and a salvage yard. The marsh was isolated from tidal effects but restoration efforts are underway as is the closure of the landfill and cleanup of the mudflats contaminated by mercury and PAHs from the refinery.

Cerrito Creek

Cerrito Creek is one of the principal watercourses running out of the Berkeley Hills into San Francisco Bay in northern California. It is significant for its use as a boundary demarcation historically, as well as presently. In the early 19th century, it separated the vast Rancho San Antonio to the south from the Castro family's Rancho San Pablo to the north. Today, it marks part of the boundary between Alameda County and Contra Costa County. The main stem, running through a deep canyon that separates Berkeley from Kensington, is joined below San Pablo Avenue by a fan of tributaries, their lower reaches mostly in culverts. The largest of these is Middle or Blackberry Creek, a southern branch.
