The Army Corps of Engineers will temporarily drop outflows from Isabella Dam to zero starting at midnight Wednesday so the power plant at the dam can shut down, according to Kern River Watermaster Mark Mulkay.

Once the power plant, run by Isabella Partners, is down, water will be routed through the dam’s gates and outflows into the Kern River will ramp back up through Thursday to 6,100 to 6,200 cubic feet per second.
