SAN MATEO COUNTY (KRON) — California may still be coping with a drought but that didn’t stop water officials from releasing tens of millions of gallons of water from Crystal Springs reservoir downstream on Thursday.
KRON 4’s J.R. Stone says the release was because of state-mandated tests of the valves that control the water supply originating at the Hetch-Hetchy reservoir in Yosemite.
Contractors have just completed construction work on the valves at Crystal Springs reservoir. Officials say the tests were successful and they actually released less water than originally estimated.
State regulations mean officials must be able to release ten percent of the trapped water in seven days. Releases are required because of efforts to support wildlife habitats and in certain emergency situations.
