Pomponio Creek is a 7.2miles westward flowing stream in San Mateo County, California that originates on the western slope of the Santa Cruz Mountains and flows into the Pacific Ocean at Pomponio State Beach.[3]
Pomponio Creek is named for Ponponio Lupugeyun (also known as José Pomponio Lupugeym), a resistance fighter against the California mission system who had a mountain hideout at the headwaters of Pomponio Creek.[4]
A dam forms Pomponio Reservoir is located at about 6.2miles upstream from the mouth.
A 15 foot high bedrock waterfall located about 2.3miles upstream from the creek mouth is an impassible barrier for immigrating steelhead trout (Oncorhynchus mykiss).[5] In 2004, the private, nonprofit Peninsula Open Space Trust (POST) purchased conservation easements on the Arata Ranch along Pomponio Creek to protect the watershed.[6]
