Overview
Carpinteria Reservoir near Carpinteria is a concrete-lined basin and serves as a terminal reservoir. The dam is an earthfill structure 31feet high with a crest length of 1,350 feet and a capacity of 40 acre-feet.
There was no extensive geologic investigation program made at the dam site. Eight power auger holes were drilled at the site, three 30 inch diameter holes, and five 20 inch diameter holes. Examination of the holes showed that the entire area was predominately layers of silt, clay, gravel and silty sand. The depth and sequence of these layers varied.
Carpinteria Dam is a part of the Cachuma Project. The Cachuma Project is located near Santa Barbara on the Santa Ynez River. The project provides irrigation water for about 35,000 acres of farmlands and municipal and industrial water for the cities of Santa Barbara, Goleta, Montecito and Carpinteria. The project is comprised of Lake Cachuma behind Bradbury Dam, Lauro Dam and Reservoir, Ortega Dam and Reservoir, Carpinteria Dam and Reservoir, Glen Anne Dam and Reservoir, Tecolote Tunnel, South Coast Conduit and Sheffield Tunnel.
