Pine Gulch Creek is a 7.6-mile-long (12.2 km)[2] south-flowing stream in western Marin County, California, United States which empties into Bolinas Lagoon.

Course

The creek parallels State Route 1. Copper Mine Gulch enters from the east, then McCormick Creek enters from the west at Pablo Point. After crossing under Olema-Bolinas Road, it feeds into the west side of Bolinas Lagoon just north of the town of Bolinas.

Habitat and human influences

Pine Gulch Creek once supported both steelhead trout and Coho salmon. The salmon run, made vulnerable by overfishing, disappeared after 1968, but briefly reappeared in 2001.[3]

Due to legal restrictions on water storage, several farms in the area pump water from the creek during the dry season, exacerbating the seasonality of its flows.[3]

Bridges

The only notable crossing of Pine Gulch Creek is the 42-foot (13 m) concrete slab at the Olema-Bolinas Road crossing, located 1.3 miles south of State Route 1. It was built in 1986.[4]
