Lagunitas Creek is a 24-mile-long (39 km)[2] northward-flowing stream in Marin County, California. It is critically important to the largest spawning runs of endangered coho salmon (Oncorhynchus kisutch) in the Central California Coast Coho salmon Evolutionary Significant Unit (CCC ESU).[3]
The stream's headwaters begin on the northern slopes of Mount Tamalpais in the Coast Range and terminate in southeast Tomales Bay, 1.5 miles (2.4 km) northwest of Point Reyes Station, California.[4] Lagunitas Creek feeds several reservoirs on Mt. Tamalpais that supply a major portion of the county's drinking water.[5]
