Lake Powell boating advisory warns of low-flying firefighting aircraft

Lake Powell boaters need to change their habits immediately between Good Hope Bay and Castle Butte, where firefighting aircraft have been scooping water for the Babylon Fire and making repeated low-altitude passes through the same corridor. Glen Canyon National Recreation Area issued the advisory on July 7 and told boaters to reduce speed, stay alert for aviation activity, and monitor marine radio channel 16 while the operation continues.

The park’s active alerts system says the warning remains in effect until further notice. That matters because the affected water sits inside Glen Canyon National Recreation Area, a more than 1.25-million-acre landscape that stretches from Lees Ferry, Arizona, to the Orange Cliffs of southern Utah. A firefighting operation in one part of that system can affect crossings, scenic cruises, angling runs, and houseboat traffic well outside the immediate drop zone.

The Babylon Fire has already pushed restrictions onto nearby public lands. The Bureau of Land Management issued a closure order on June 29 for public lands administered by the Monticello Field Office and amended it on July 1. Canyonlands National Park closed The Needles district on June 28 because of the fire, then kept that closure in place in updates on July 1 and July 9 as the blaze moved north toward UT-211. For travelers moving around the Colorado Plateau, that has meant a tight squeeze on routes, access points, and day-trip plans.

This is not new territory for Lake Powell. During the June 2025 Bridge Creek Fire response near Navajo Mountain, about 5 miles from the lake, Glen Canyon used Lake Powell for firefighting aircraft that included helicopters and fixed-wing Super Scoopers, with rangers providing vessel support. In July 2025, the park said Super Scoopers would draw water between buoys 43 and 49. Glen Canyon’s aviation materials also spell out why the lake keeps getting pulled into wildfire operations: aircraft deliver water, move firefighters, and provide aerial observation.

The park has been bracing for lower water, too. In March, Glen Canyon said Bullfrog Marina and Bullfrog Boat Rentals/Fuel Dock would shift into deeper water near Halls Crossing because lower lake levels were expected for the summer. Add that to the Babylon Fire response, and Lake Powell is once again functioning as both vacation water and active firefighting ground. That is the change boaters need to read first: stay out of the aircraft corridor, keep speed down, and treat the channel as a working zone until the low-flying traffic clears.
