Lake Powell Water Levels and Boat Ramps

Lake Powell rises and falls by many feet from year to year, and the level changes almost everything about a trip: which ramps are open, which shortcuts work, how far you walk to Rainbow Bridge and which beaches have water. Here is what the numbers mean for a day on a jet ski or boat.

How the Lake Level Is Measured

The level is given in feet above sea level at Glen Canyon Dam. Full pool is 3,700 feet. Through the drought years the lake has run far below that, and in 2026 it set a new record low of about 3,516 feet in September before heavy October rains pushed it back up to around 3,540 feet.

The lake usually drops through the fall and winter, reaches its low point in early spring, then rises with mountain snowmelt from about May into July. How much it rises depends on that winter’s snowpack in the Rocky Mountains.

Where to Check the Current Level

The National Park Service posts the current elevation, along with the status of every launch ramp, on its Changing Lake Levels page. Check it the week of your trip and again the morning you go, because ramps open and close as the water moves.

Key Levels to Know

These are the minimum safe elevations the Park Service lists for each spot. They can change when ramps are extended, so treat them as a guide and confirm on the NPS page.

What Low Water Means on a Jet Ski

• Longer routes: with Castle Rock Cut closed, plan extra time and fuel to reach Warm Creek Bay, Padre Bay and the canyons beyond. See our jet ski routes.
• No mid-lake fuel: Dangling Rope Marina closed for good in 2024, so there is no fuel between the south-end marinas and the Bullfrog area, about 100 miles apart.
• New hazards: rocks, reefs and sandbars that were deep underwater can sit just below the surface. Slow down near points, islands and canyon mouths, and watch for hazard buoys.
• Beaches move: at low water Lone Rock stands on dry sand and the shoreline at many beaches moves far out. New sandy coves also appear all over the lake.
• Canyons change: slot canyons such as Antelope Canyon and Labyrinth Canyon end sooner by water, while places that were drowned for decades, like Cathedral in the Desert, come back into the light.

What Higher Water Brings

When the lake rises, Castle Rock Cut reopens as a short path from Wahweap Bay to the rest of the lake, the Rainbow Bridge dock reconnects to the trail, more launch ramps reach the water and the side canyons fill farther back. Either way, Lake Powell is open and there is always more lake than you can see in one trip.

We Keep Up With the Lake for You

We rent at Wahweap, Antelope Point, Bullfrog and Halls Crossing and launch from whichever ramps the lake level allows, so your rental is ready on the water. Our crew is on the water every day, so we know which areas are running well right now. Text us with your dates and we will tell you what to expect, then book your jet ski rental or boat rental online.
