Lake Powell boating rules and regulations
Speed and wake zones, right of way, life-jacket law, operator age limits and the Glen Canyon rules that apply across the lake — enforced by the National Park Service and Utah and Arizona authorities.
Updated
On Lake Powell, keep to 5 mph within 150 feet of shore, docks, swimmers and marinas, and a safe speed everywhere else. Every boat needs a Coast Guard–approved life jacket per person, and children under 13 must wear one underway. Personal watercraft are banned in side canyons, beach camping requires a portable toilet, and all boats must be cleaned, drained and dried against invasive mussels. Rules are enforced by the National Park Service and Utah and Arizona authorities.

What are the navigation rules of the road?
| Rule | What it requires |
|---|---|
| Right of way | Powerboats yield to non-powered vessels; when crossing, the boat on your right has the right of way; an overtaking boat must keep clear; give way to vessels restricted in their ability to maneuver. |
| Speed limits | 5 mph within 150 feet of shore, a dock or a swimmer; wakeless speed in narrow channels; obey marked no-wake zones; always keep a safe speed for conditions. |
| Navigation lights | Required sunset to sunrise: red to port (left), green to starboard (right), a white stern light visible 360°, and an all-round white light when anchored. |
| Sound signals | One short blast: passing on the port side; two short: passing on starboard; three short: operating astern; five or more short blasts: the danger signal. |
Where do speed and wake limits apply?
5 mph zones:
- Within 150 feet of any swimmer
- Within 150 feet of shore where people are present
- All marina areas and fuel docks
- Within mooring areas and anchorages
- Under bridges and in narrow channels
Wakeless-speed zones:
- Marked no-wake zones (orange buoys)
- Within 500 feet of marina entrances
- Narrow canyons and channels
- Near floating restrooms
- In emergency situations
In open water there’s no posted speed limit, but you must keep a safe speed for the weather, traffic and visibility — and you’re liable for any damage your wake causes.
What rules are specific to Glen Canyon?
Lake Powell sits inside Glen Canyon National Recreation Area, so National Park Service regulations apply across the water:
- Personal watercraft are prohibited in side canyons
- Quiet zones are enforced in designated areas
- Beach camping requires a portable toilet
- Fire restrictions vary by season
- Overnight mooring in a marina requires a permit
- The fuel dock has the right of way
Who can legally operate a boat?
Lake Powell straddles two states, and operator-age rules differ on each side:
| State | Operator requirements |
|---|---|
| Utah | 12–15: may operate with adult supervision; 16–17: may operate if they’ve passed boater education; 18+: no restrictions; PWC operators must be 16+; a boater-education card is required for those born after 1993. |
| Arizona | 12–15: may operate with an adult on board; 16+: may operate without supervision; PWC operators must be 12+; boater education is required for 12- to 15-year-olds; out-of-state visitors follow their home state’s rules. |
Common violations and penalties

|---|---|---|
| Boating under the influence (BUI) | Up to $5,000 fine, 6 months jail, loss of boating privileges | BAC of 0.08% or higher |

| No life jackets | $100–500 per violation | Children under 13 must wear one at all times underway |

Frequently asked questions
What is the speed limit on Lake Powell?
5 mph within 150 feet of any swimmer, of shore where people are present, of docks, marinas and fuel docks, and under bridges and in narrow channels. Open water has no set limit, but you must keep a safe speed for conditions and you’re responsible for any damage from your wake.
Do kids have to wear life jackets on Lake Powell?
Yes — children under 13 must wear a Coast Guard–approved life jacket at all times while the boat is underway. Every person aboard must have one readily accessible, whatever their age.

There’s no general license, but boater-education rules apply by age and state. Utah requires education for 16- and 17-year-olds operating alone and for those born after 1993; Arizona requires it for 12- to 15-year-olds. Out-of-state visitors generally follow their home state’s rules.
What are the penalties for boating under the influence?
A BAC of 0.08% or higher is boating under the influence, carrying up to a $5,000 fine, up to six months in jail and loss of boating privileges. The rules are enforced by the National Park Service and Utah and Arizona authorities.

Beach camping requires a portable toilet and you must pack out all trash. Sewage and gray water can’t be discharged near shore or swimming areas, personal watercraft are prohibited in side canyons, and every boat must be cleaned, drained and dried and pass inspection to prevent invasive mussels.
