A High Flow Experiment (HFE) will occur April 24-27 from the Glen Canyon Dam in Arizona resulting in large quantities of water being released into Lake Mead in the coming days. This will lead to a temporary closure at Pearce Ferry Launch Ramp. Our crews will be making adjustments to boat ramps and facilities near beaches in preparation for this high-water event.
Separate from the High Flow Experiment, Lake Mead will also have several additional closures for new installations and spring equipment training.
4/25 - 4/30 - PEARCE FERRY launch ramp will be CLOSED at 2:00 p.m. on (4/25) and re-open at 2:00 p.m. on (4/30).
4/26 - 4/27 - BOULDER BEACH / SWIM BEACH AREA - Crews will be moving toilets and dumpsters. The area will remain open but please use caution as heavy equipment will be in the area.
4/24 - 4/28 - A new fishing pier is being installed at PWC beach. The road will be CLOSED to repair the area and install signage. The road will re-open at 4:00 p.m. on (4/28).
