Repairs to a damaged tunnel inside the power plant at the base of Isabella Dam were completed Saturday, just seven days after the project began, according to an attorney for Water Audit California, a public interest group suing to keep water in the Kern River. Releases from the dam had been reduced to about 100 cubic feet per second during the repairs and are now expected to ramp back up, according to attorney William McKinnon who has been coordinating with the Army Corps of Engineers and power plant owner Isabella Partners. Roger Kirk, the manager of the power plant, referred questions about the project to McKinnon.
