Lake Mead Boat Ramps vs the Water Level
Published NPS ramp elevations, paired with the daily gauge reading.
- Lake Mead is at 1,041.38 feet as of .
- The Hemenway Harbor launch ramp was extended in summer 2025 by about 200 feet, down to a ramp-end elevation of approximately 1,020 feet, with a design allowing extension to about 1,000 feet (per the National Park Service).
- That puts today's water surface about 21.4 feet above the extended Hemenway ramp end.
Why ramps close as the lake drops
A launch ramp is only usable while its paved end sits in enough water. Every foot of lake decline moves the waterline down the ramp — and Lake Mead has fallen 178 feet below full pool. The National Park Service has repeatedly extended or relocated ramps as levels declined.
