Drop Structure -Migrating
salmon are unable to proceed
further up Marsh creek
because of this flood control
barrier (located between
Sunset and Delta Roads).
Spawning Salmon - Salmon
make their way up Marsh Creek
every winter seeking suitable
spawning areas.

A 2004 University of California study found that this reach of Marsh Creek contains
abundant and suitably sized gravels for salmonid spawning. The project will also
indirectly benefit other species by raising awareness of Marsh Creek. All around
California, the annual return of the salmon is a significant event worthy of festivals and
media coverage. These migrating salmon will present an excellent opportunity to
educate residents of the many ways that their actions can benefit water quality, habitat,
and ecological health. The East Bay Regional Park District Marsh Creek trail runs
alongside the drop structure and the fish ladder will be in a highly trafficked and highly
visibly location, improving the opportunity for education. This project enjoys strong
support and approval of the county flood control district, the City of Brentwood, the
Department of Water Resources, and it is the top priority action of the Friends of Marsh
Creek Watershed. Now that project costs are fully funded, construction of the Marsh
Creek Fish Ladder is scheduled for 2008!

Chinook salmon have lost more than 90%
of their historical range in California due
barriers. This project will restore access
to approximately seven miles of Marsh
and Sand Creeks in eastern Contra Costa
County by constructing a fish ladder at the
Marsh Creek drop structure in Brentwood.
This project will benefit the Chinook
salmon by providing access to seven
miles of stream including over two miles
of excellent spawning habitat.
