La Honda Creek

La Honda Creek is a 7 mi long stream on the Pacific slope of the Santa Cruz Mountains and is a tributary of San Gregorio Creek. From its source (37.3923°N, -122.2918°W) near Bear Gulch Road and Skyline Boulevard (CA 35) in San Mateo County, California, La Honda Creek's water flow south to its confluence with Alpine Creek to form San Gregorio Creek in La Honda, and thence to the Pacific Ocean.

History
The Spanish historic name for La Honda Creek was Arroyo Hondo, meaning "deep stream". The creek was listed as Arroyo Ondo on several diseños on the Mexican land grants and as Arroyo Hondo on the 1856 Rancho Cañada de Raymundo map.

Watershed and Course


The La Honda Creek watershed drains 12.3 sqmi. A large part of the creek's upper watershed is in La Honda Creek Open Space Preserve.

California State Route 84 (CA 84) follows the valley of the creek from Sky Londa to San Gregorio.

Four named tributaries, Woodhams, Langley, Woodruff and Weeks Creeks, flow into La Honda Creek.

Ecology
The La Honda Creek watershed has been documented as historically supporting a salmonid population, including steelhead trout (Oncorhynchus mykiss) and potentially coho salmon (Oncorhynchus kisutch), however sediment eroding into the creek coupled with natural logjams present barriers to fish passage. A 1985 California Department of Fish and Wildlife survey reported steelhead up to 2 mi upstream of Weeks Creek, the highest named tributary, and reported that La Honda Creek provides good spawning and rearing habitat for steelhead downstream of Woodruff Creek, and resident rainbow trout (the landlocked form of steelhead trout) upstream of Woodruff Creek.
