In an effort to re-establish a viable population of coho salmon, the California Department of Fish and Wildlife (DFW) in 2003 began a multiple year effort of planting coho salmon into Walker Creek. MMWD has been a partner in these efforts by conducting monitoring surveys to help evaluate the success of the program. The district operates Soulajule Reservoir on Walker Creek, which links the district to the fate of salmon in the watershed.
Supported in part by a DFW Fisheries Restoration Grant, the district
conducted a series of monitoring studies between 2003 and 2012 to assess
the coho population of Walker Creek. The surveys also gathered
information on steelhead and other fish of the creek, water
temperatures, and aquatic invertebrates. The Marin County Office of
Education’s Walker Creek Ranch was also a partner in this effort, and
the surveys could not have been completed without the help and support
of the Marin County Resource Conservation District and local ranchers.
MMWD has summarized the monitoring results in a compilation report, for
the 2005 - 2010 monitoring period, that is a comprehensive report on
the salmon populations of Walker Creek. The monitoring reports from 2011
and 2012 are also presented below. As efforts progress to recover coho
salmon throughout their range in California, Walker Creek will provide
insights into how to make recovery successful and, along with Lagunitas
Creek, it may one day be at the heart of that success.
