Summary

The San Antonio Creek Valley watershed (SACVW) is located in western Santa Barbara County about 15 miles (mi) south of Santa Maria, California and 55 mi north of Santa Barbara, California.

Groundwater withdrawal from pumping has exceeded the amount of water replenishing the basin, causing groundwater declines of more than 150 feet in parts of the valley between 1947 and 2018, and reducing base flow in San Antonio Creek at the western end of the SACVW. Agricultural water use (primarily for the present-day irrigation [...]
