Lake Powell & Glen Canyon Dam Info

Glen Canyon Dam at Lake Powell

Here is some information and history about Lake Powell and Glen Canyon Dam that you may find helpful and interesting.

The Colorado River impounded behind Glen Canyon Dam near Page Arizona forms Lake Powell which is 560 feet deep when filled to capacity (3700 feet above mean sea level). The lake follows the flooded river gorge for 186 miles with many canyons and coves to explore along shoreline encompassing 1960 miles. The lake covers over 160,000 surface acres at full pool. Two inundated rivers, the San Juan and Escalante, branch off the Colorado River and comprise major portions of the reservoir.

Most of the shoreline is inaccessible with only four areas where access from any vehicle is possible. There are full service marinas and launch ramps at these access sites: Wahweap, Stateline, Antelope, Bullfrog, Hall’s Crossing and Hite (launch ramp only). A mid-lake marina, Dangling Rope, provides gas and services for boaters traveling the lake. There is no shore based access to Dangling Rope Marina. Dirt road access and primitive launching is available at Piute Farms on the San Juan Arm, Farley’s Canyon near Hite and Blue Notch Canyon in Good Hope Bay when the lake is near full pool.
