In the mid-1950s, the Cachuma Project was completed by the United States Bureau of Reclamation with the participation of Montecito Water District and other South Coast water suppliers. Lake Cachuma was constructed to address water supply shortages caused by a serious drought between 1947 and 1951. The Cachuma Project ended water supply shortages for the south coast water agencies up until the early 1970s when the Montecito and Goleta Water Districts declared moratoriums on new water services due to an increase in customer water demand that exceeded available supplies. State Water Project and Supplemental Water Purchases are delivered into Cachuma Lake before being received by the District. View a presentation on Cachuma Project History (COMB)
