Lake Powell

Closed all boat ramps 4/6/20

Rivers feeding Lake Powell are running at 75% of the average rate. Lake Powell is up 31.00 feet from this time last year. Lake Powell water level is starting to go down. Watch your stuff, stay safe.

As of April 1, Glen Canyon National Recreation Area will offer very limited services outside those that support visitor or resource protection. At Glen Canyon National Recreation Area, the following services and operations will be suspended in order to comply with the state, county, local and tribal orders. All campgrounds in Glen Canyon are closed: Wahweap, Bullfrog, Halls Crossing, Lone Rock Beach, Lees Ferry. Public restrooms are closed.

  • Public boat ramps at the Wahweap Marina, Antelope Point Marina, Lees Ferry, Bullfrog, and Halls Crossing remain open to the public. We will continue our partnership with the states of Arizona and Utah in prevention of quagga mussels. Inspection stations will be open.



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 Charles Hall Ferry, The Charles Hall Ferry, which runs between Halls Crossing and Bullfrog, is now closed.

The ferry will not be operational from March 16, 2020 to May 16, 2020

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 have been 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.

Watch Your Step on Lake Powell Beaches: Quagga mussel shells are sharp and tiny. They will cut through skin, clothes, and paws. Please wear water shoes and put doggie booties on your pets when recreating on the beaches.

A dead bat found recently near Lees Ferry tested positive for rabies. Do not approach wildlife or touch bats, living or dead. Make sure your pets are vaccinated.

New Waste Disposal Requirements for Coyote Gulch Visitors
Due to increased visitation and the lack of toilets at Coyote Gulch, hikers in the popular Coyote Gulch area of the Escalante backcountry will now be required to pack out their own solid waste using a portable waste containment bag.

Public Health, Environmental and Wildlife agencies from Utah and Arizona are jointly issuing a mercury fish advisory for striped bass in the southern portion of Lake Powell from Dangling Rope marina to the dam. The National Park Service and Utah Division of Wildlife Resources (UDWR) have recently detected additional adult quagga mussels in Lake Powell. Since this time last year, the water levels at Lake Powell have dropped which has exposed shorelines that were previously underwater.

To help stop the spread of mussels:

You must clean and drain your boat before you leave the vicinity of the lake.

You must dry your boat the required amount of time before
moving it to another body of water.

OR you can have your boat professionally decontaminated.

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 ferry that runs between Bullfrog and Halls Crossing is running on its winter schedule. Utah travelers should know that without the ferry, State Route 276 does not connect and they must use Hwy 95 to drive north and south around Lake Powell. Find more information on the ferry page of the UDOT website.

Note: Regarding the 2-stroke, 4-stroke engine issue: According to the Code of Federal Regulations Title 36, 7.70(e)(3): No one may operate a PWC that does not meet the 2006 emission standards set by EPA for the manufacturing of two-stroke engines. This also true for Lake Mead NRA.


Lake Mead

Note April 1: Some Park Facilities Temporarily Closed see

All road on the Nevada side of Lake Mead are closed, the road on the Arizona side are open.

Water levels: Lake Mead level is up about 8 feet from last year at this time. The lake water level is about 43.5% 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.

Remember, Styrofoam and glass are never allowed in the park. Thank you for keeping your park clean and trash free.

The Bureau of Reclamation’s Lower Colorado Region is lowering water levels in Lake Mohave beginning in late September to aid in harvesting razorback suckers, a species native to the Colorado River, from lakeside rearing ponds.

No one may operate a personal watercraft (PWC) that does not meet the 2006 emission standards set by EPA for the manufacturing of two-stroke engines.
