Cavitation repairs at Gavins Point Dam
Steve Neumann, Senior Mechanic at Gavins Point Dam. "We try to perform cavitation repairs every year on at least one unit. Each year, we un-water the units, one at a time and perform an internal inspection of the draft tube and scroll case, which includes taking blade clearance readings, inspecting the wicket gates, taking wicket gate clearance readings, and evaluating the overall condition of the scroll case.”
