Lake Powell boating safety, start to finish
Required gear, navigation hazards, weather awareness, the rules and what to do in an emergency — everything you need to come home safe from a big, remote lake.
Updated
Lake Powell is safe for prepared boaters, but it is big and remote — 1,960 miles of shoreline, most of it with no cell service, and help that can be hours away. Carry the required safety gear, watch the weather, know the navigation hazards, and save the emergency numbers below. In any emergency, call 911 or hail VHF channel 16.

Emergency contacts to save before you launch
Program these into every phone aboard, and keep a waterproof copy on the boat. On the water, VHF channel 16 reaches the Park Service faster than a phone. The emergency procedures guide has the full table and step-by-step response.

Why does Lake Powell need extra preparation?
This is America’s second-largest reservoir, and its scale is the safety story. A few numbers explain why boaters plan ahead here:
- 186 miles long with limited access points on the water.
- 1,960 miles of shoreline and more than 90 major side canyons to get turned around in.
- About 80% of the lake has no cell service.
- Two to four hours for help to reach the remote arms of the lake.
- 20°F to 115°F across the year, with sudden wind and monsoon storms.
What are the most common Lake Powell emergencies?
Based on National Park Service incident patterns, five situations account for most calls. Knowing them is the first step to preventing them:
- Mechanical failure — engine, steering and electrical trouble far from help. Prevent it with maintenance, spare parts and basic repair know-how.
- Grounding and collisions — striking submerged rock, most often when the lake is low. Prevent it with a depth finder, current charts and a bow watch.
- Medical emergencies — injuries and heat illness hours from a hospital. Prevent it with first-aid training and a full medical kit.
- Weather incidents — sudden storms, high wind and lightning on open water. Prevent it by watching the sky and having a shelter plan.
- Carbon monoxide — poisoning from generators and engines on houseboats. Prevent it with CO detectors and good ventilation.
How should you prepare before a trip?
Most emergencies are avoidable. Run this pre-trip checklist before every launch:
- Inspect every piece of safety gear — life jackets, fire extinguisher, flares, first-aid kit.
- Review the forecast and set clear go / no-go limits for wind and storms.
- File a float plan with someone on shore: route, return time and who’s aboard.
- Program the emergency numbers into every phone and post them where the crew can see.
- Give a crew safety briefing: life jackets, the radio, man-overboard and fire response.
Designate a sober captain, know your boat’s limits, and carry a backup way to communicate. The Park Service posts current conditions and safety alerts at nps.gov/glca.
