- Thumbs - Country Information - Above the Dam - Over the Edge - Below the Dam - Overflow valves - Over the Top - Lake Mead - Testing the Overflow Valves We were lucky enough to witness the testing of the dam's overflow valves in June 1998. New valves had been fitted and needed to be tested. They'll probably never be used again unless an emergency arises.
