Boating Changes at Lake Powell

Ramps closed at night

If you plan on visiting Lake Powell during the July 4 holiday, or anytime this summer, plan your visit so you don’t arrive at a major launch ramp between 10 p.m. and 5:30 a.m.

If you arrive during those hours, you won’t be able to launch your boat.

The National Park Service has closed the ramps from 10 p.m. to 5:30 a.m. Utah time (9 p.m. to 4:30 a.m. in Arizona).

The nighttime ramp closure is part of a continuing effort to keep quagga and zebra mussels out of the lake.

Starting June 29, NPS personnel will be at the lake’s major launch ramps from 5:30 a.m. to 10 p.m. every day. Every boater will be asked a series of questions before they launch their boat.

Boats that have been on waters infested with quagga or zebra mussels must be decontaminated before they’re launched.

“We’re 100 percent behind this change,” says Wayne Gustaveson, the Utah Division of Wildlife Resources’ lead aquatic biologist at the lake.

“Quagga and zebra mussels attach themselves to boats,” Gustaveson explains. “That’s the major way they move among bodies of water.

“Contacting every boater at a major ramp will help ensure quagga and zebra mussels don’t enter the lake.”

If you launch at one of the primitive ramps at Hite, you must complete a self-certification form before launching. The forms are available at and at the launch ramps.

The form will ask you a series of questions. The answers to these questions will let you know whether you can launch your boat.
