IF Hoover Dam fails catastrophically, then Davis and Parker dams will fail as well, and the entire Colorado River watershed from the Las Vegas area down to the Mexican border (and beyond) is in danger.
The Bureau of reclamation is well aware of the importance of Hoover Dam, and they keep careful watch on the dam and its "head" (load of water weight based on water level behind dam).
I was in DoE/BoR when water was allowed to flow over the bypass to maintain integrity of Hoover Dam. It's a critical element to a three-state area plus Mexico, and good people are [were] working to maintain structural integrity.
