SANTA YNEZ RIVER VALLEY GROUNDWATER BASIN REPORTS

The Santa Ynez River Water Conservation District was formed in 1939 and protects water rights and supplies within the Santa Ynez River watershed, manages releases of water from Bradbury Dam to replenish downstream basins along the River and on the Lompoc Plain, and provides water management throughout the area. The Annual Engineering and Survey Report on Water Supply Conditions of the Santa Ynez Water Conservation District are available.
