San Luis Reservoir is kind of a special case, not a “normal” reservoir...it is filled by a canal (CA Aqueduct) that supplies Westside farmers and L.A.. So it’s level is fairly predictable, with Sept./Oct. being the low water level point. Here are current lake levels for more “normal” lakes: http://cdec.water.ca.gov/cgi-progs/current/RES

Didn’t see Anderson, Calero, Uvas, etc on that list and they look about normal to me, for California....
