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[edit]

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.

History[edit]

Habitat and human influences[edit]

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[edit]

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]
