The "Dead pool" is the section of Lake Mead that is no longer deep enough to be used for boating or other activities. It is the lowest point of Lake Mead and will be reached when the water level drops to 1,075 feet above sea level.  The name "dead pool" may sound ominous, but it refers to the fact that the water in this section is still, with no current. It also refers to the fact that no more water will flow into Lake Mead once it drops below 1,075 feet. The water in the dead pool area will evaporate and eventually disappear.
