These quarries are located in Clearlake Oaks, off Point Lake View road in Lower lake, and Hidden Valley Sand and Gravel located on Cache Creek. Clearlake Lava started a successful ready mix concrete operation and has expanded it over the years and is now serving all of Lake and Colusa counties as well as portions of neighboring counties.
