    Pinole Creek Watershed Sediment Source Assessment January 2005 Prepared by the San Francisco Estuary Institute for USDA Natural Resources Conservation Service and Contra Costa Resource Conservation District San Francisco Estuary Institute The Regional Watershed Program was founded in 1998 to assist local and regional environmental management and the public to understand, characterize and manage environmental resources in the watersheds of the Bay Area. Our intent is to help develop a regional picture of watershed condition and downstream effects through a solid foundation of literature review and peer- review, and the application of a range of science methodologies, empirical data collection and interpretation in watersheds around the Bay Area. Over this time period, the Regional Watershed Program has worked with Bay Area local government bodies, universities, government research organizations, Resource Conservation Districts (RCDs) and local community and environmental groups in the Counties of Marin, Sonoma, Napa, Solano, Contra Costa, Alameda, Santa Clara, San Mateo, and San Francisco. We have also fulfilled technical advisory roles for groups doing similar work outside the Bay Area. This report should be referenced as: Pearce, S., McKee, L., and Shonkoff, S., 2005.

Center for Ecosystem Management and Restoration CONTRA COSTA COUNTY Marsh Creek Watershed Marsh Creek flows approximately 30 miles from the eastern slopes of Mt. Diablo to Suisun Bay in the northern San Francisco Estuary. Its watershed consists of about 100 square miles. The headwaters of Marsh Creek consist of numerous small, intermittent and perennial tributaries within the Black Hills. The creek drains to the northwest before abruptly turning east near Marsh Creek Springs. From Marsh Creek Springs, Marsh Creek flows in an easterly direction entering Marsh Creek Reservoir, constructed in the 1960s. The creek is largely channelized in the lower watershed, and includes a drop structure near the city of Brentwood that appears to be a complete passage barrier. Marsh Creek enters the Big Break area of the Sacramento-San Joaquin River Delta northeast of the city of Oakley. Marsh Creek No salmonids were observed by DFG during an April 1942 visual survey of Marsh Creek at two locations: 0.25 miles upstream from the mouth in a tidal reach, and in close proximity to a bridge four miles east of Byron (Curtis 1942).

  • The F Street Trailhead Is a Hidden Gateway & How the Franklin Hills
    View of the Franklin Hills and the canyon above F Street from above the track at Alhambra High School (Photo by Seth Adams, 5-2020) The F Street Trailhead is a Hidden Gateway & How the Franklin Hills Were Saved F Street Trailhead, Carquinez Strait Regional Shoreline By Seth Adams, Co-Chairman, Thousand Friends of Martinez Hike Start: top of F Street Distance: 0.8 miles roundtrip, or longer Time: 45 minutes roundtrip, or longer Moderate hike What are the Franklin Hills? How were they saved? Why go there? They are the scenic backdrop for Martinez and its western border from Highway 4 to the Carquinez Strait. They’re a constant—everyone in Martinez loves them, whether you grew up or moved here—and they’ve resisted change. At the simplest we love them because they’re our backyard, they mean Martinez, and most of us see them every day. In May 2020 Martinez residents are sheltering in place from the coronavirus pandemic, luckily with nearby access to wonderful open spaces. Martinez is surrounded by four regional parks. The recently renamed Radke-Martinez Regional Shoreline to the north and Briones Regional Park to the south are the most well-known. Waterbird Regional Preserve is east across Highway 680. Carquinez Strait Regional Shoreline includes the Franklin Hills west of downtown. Most people who go there use the Nejedly staging area along Carquinez Scenic Drive, or the entrances further west where the George Miller Trail begins. Less well known is the F Street Trailhead at the south edge of Alhambra High School. This article is in two major parts.
