Casitas logoCasitas Municipal Water District (CMWD) is the primary water supplier in the watershed, providing water to both water resale agencies and retail customers. The City of Ventura is Casitas’ largest customer.

One of CMWD’s important functions is to serve as the “backup” water supply for a number of their customers, including 9 water suppliers as well as farmers, when groundwater supplies become depleted.

CMWD’s service area encompasses 150 square miles and includes the city of Ojai, Upper Ojai, the Ventura River Valley area, the city of Ventura south to about Mills Road, and the Rincon and beach area to the ocean and Santa Barbara County line.

CMWD gets its water from Lake Casitas, which is fed by both the surrounding drainages and water diverted from the Ventura River. The district also operates 1 well in the Mira Monte area.
