For the last ten years we have been experiencing the drought in Arizona, the water behind Hoover Dam dropping to alarming levels.
Rain has been so constant this year that reservoirs are all filling up and Lake Mead, created by Hoover, is recovering.
Grand Canyon flooded when an earthen dam broke. Scouts had to be airlifted out. They claimed to be prepared, but they stayed near water after torrential rains and repeated warnings from the park rangers.
