Water releases through the damaged main spillway at Oroville Dam were scaled back Thursday to allow crews to reach and remove a pile of debris that has built up at the bottom of that chute, officials said.
Feeling confident they’ve created sufficient empty space in Lake Oroville for the time being, state Department of Water Resources officials said they reduced spillway outflows so they could address another looming challenge: restarting the dam’s hydroelectric plant, which can release additional water when operational.
Aquafornia’s Water Word of the Week from sister site Aquapedia, the Water Education Foundation’s vetted, online water encyclopedia, is Hydroelectric Power.
According to an Aquapedia excerpt, “Hydroelectric power is produced when water turns a turbine connected to a generator. This water is stored behind a dam at elevation. Gravity causes water to drop toward a turbine propeller.
“The Obama administration’s announcement Monday of sweeping new rules aimed at curbing global warming emissions from power plants could boost profits at Silicon Valley companies that make solar panels, energy efficiency software and other clean technology.”

“That’s because the drought is hammering California’s ability to generate electricity from hydroelectric power …”
