After each phase of the five days of testing, Bureau of Reclamation officials carefully inspected the left spillway for any damage. Absolutely no cavitation damage could be detected. The design and installation of the air slot was a complete success. Through the spillway had roared water at over one thousand five hundred tons per second, at a velocity exceeding one hundred miles per hour, yet it had caused no cavitation.
