San Antonio Creek Spreading Grounds

San Antonio Creek Spreading Grounds Rehabilitation Project (V-2)

The 'spreading grounds' historically existed to recharge groundwater in the Ojai basin using water delivered through the Matilija Conduit from Matilija reservoir. This was the primary intent of Matilija Dam when constructed in 1948, but the practice was discontinued with the construction of Casitas reservoir in 1956.

This project would rehabilitate the historic spreading grounds to enhance groundwater recharge using water diverted from upper San Antonio Creek below Senior Canyon. The project includes construction of recharge wells, as well as a monitoring well.

• Diversion of a portion of the precipitation that is typically lost from within the San Antonio Creek Sub-Watershed to the rehabbed spreading grounds using project facilities.
• Increase the groundwater recharge and storage in the Ojai Valley Groundwater Basin (OVGB), thereby enhancing the reliability of production from local water supply wells.
• Reduce local reliance on already-limited surface water supplies from the Casitas Municipal Water District (CMWD.)

A stakeholder group inclusive of the Ojai Basin Groundwater Management Agency, the Ojai Water Conservation District, the Golden State Water Company, the Casitas Municipal Water District, and the Ventura County Watershed Protection District is working cooperatively to complete this groundwater recharge and supply project.

The $1.4 Million project is funded by the combination of a $1.3 Million Prop 50 Implementation Grant from the State of California and approximately $100,000 in local match contributions from the five stakeholders.
