Pine Gulch is a 19.8 square km watershed in coastal Marin County, California, and is the primary freshwater input to the Bolinas Lagoon. The watershed supports a population of steelhead trout (O. mykiss) and it is generally accepted that the watershed supported a native self-sustaining population of coho salmon (O. kisutch) into the 1970's. Numerous fish surveys performed by the California Department of Fish and Game, National Park Service (NPS), and others had not detected coho in Pine Gulch since 1968, and it had been presumed extirpated, possibly due to a combination of drought and in-stream damming during the mid 70's. NPS biologists have conducted comprehensive surveys for juvenile and adult salmonids on PIne Gulch since 1997. Results indicate approximately 538 juvenile coho distributed in two clusters, suggesting they may have originated from more than one redd.
