Didn’t see Anderson, Calero, Uvas, etc on that list and they look about normal to me, for California....
Santa Clara Valley WD indicates that they import at least 253,000 acre-feet of water per year (primarily stored in Anderson Reservoir), so unfortunately the levels there aren’t really an indication of drought conditions either. (Draining Shasta Dam to fill San Luis & Anderson, etc.).
