Lake Mead Water Level
Here are the historical and current Lake Mead water levels &
Lake Mead water elevation as measured at Hoover Dam.
The water level in Lake Mead is "full" at 1225' in elevation, and overflows into the spillways at 1229'.

The elevation of the Colorado river, i.e:, the bottom of Black Canyon is roughly 645'.
This has been a great couple of years for scuba diving in Lake Mead due to the lower than normal water levels. There's all sorts of treasures remaining from the 1930s while the dam was under construction that are now within semi-recreational scuba and technical air/trimix scuba diving limits.
The purple cells denote severly low elevations.
