Water releases from the Glen Canyon Dam fluctuate based on power needs, which can sometimes leave downstream river users high and dry - literally! Generally, less water is released on Sundays. The Colorado River provides water for 40 million people across the Southwest.

The public is asked to use extreme caution when using the public launch ramps at Lake Powell. Most of the main boat ramps are open. The deepest launch ramp at Lake Powell continues to be Wahweap main ramp. Different boat/trailer combinations require varying depths of water, so remember to assess the water depth for your boat before launching.

Castle Rock Cut and Antelope Point Marina Launch Ramp Fully Open. Boaters should still be aware that while the ramp is open, launching at these water levels is not safe for all sizes of boats and launching is at your own risk.The Wahweap fish cleaning station will be closed until further notice.

While the main ramp is closed, the north launch ramp remains open and available to all boaters and another launch location for vessels up to 20 feet in length was added east of the main ramp.

Lower water levels have exposed rock formations that havebeen hidden underwater for years. Boaters must be extra vigilant to avoid an unpleasant run-in with the Navajo Sandstone. At the current lake level, there are no available marina facilities or public launch ramp at Hite Marina.

Glen Canyon asks visitors to play it safe while in the park. Bring water, snacks, hats, sunglasses and sunscreen - and use them. Visitors on the water should wear life jackets. Cliff jumping is not recommended and illegal at 15' or greater. Boating after dark is discouraged due to sub-surface water hazards.

Wahweap Main and Bullfrog launch ramps and screening for the invasive mussels by trained personnel will be mandatory for all vessels. Currently, Lake Powell is believed to be free of quagga and zebra mussels. However, zebra and quagga mussels pose a major threat to Lake Powell if they were to become established. Experts fear that zebra mussels could spread quickly through the Colorado River watershed and potentially establish themselves in other river systems.

The ferryBeginning Thursday, Dec. 17 the Halls Crossing to Bullfrog Ferry will launch from the Halls Crossing Main Ramp. This is due to current lake levels. At Bullfrog, the Ferry is launching from the North Ramp. Local signage will direct travelers. For more information about the Ferry please call the Utah Department of Transportation at 435-893-4747, or visit the ferry page of the UDOT website.


Lake Mead

Water levels: Lake Mead level is down about 14 feet from last year at this time. The lake water level is about 40% full. Launch ramp conditions at Lake Mead have improved significantly thanks to a $1.5 million construction project that began in late July 2017. The project involves underwater excavation, dredging, grading and construction of reinforced concrete ramps. The concrete ramps will extend down to the water’s edge, and concrete panels or steel pipe mat will extend roughly six feet below the current lake water surface.

The NPS is focused on ensuring employees, their families, volunteers and visitors are safe by following the most current guidance from the CDC, Office of Personnel Management, Office of Emergency Management, and other federal, state and local health authorities.
