Spring runoff is boosting the level of Lake Powell by about a foot a day/Kurt Repanshek file photo from May 2021

With spring runoff growing by the day, Lake Powell's water level is increasing about a foot or so a day, according to the National Park Service at Glen Canyon National Recreation Area.

On Friday the lake's elevation was 3,543.4 feet above sea level. By 10 a.m MT on Saturday it had increased to 3,544.6 feet.

While the rising lake level is good news for boaters, the Park Service notes that the spring runoff down the San Juan and Colorado rivers is carrying a large amount of debris. "Boat operators need to use extreme caution while navigating the lake, as large debris is present," a park release said. "Specifically, above Halls Crossing (at buoy 100), the park’s Aids to Navigation (ATON) crew reported logs and limbs beneath the surface of the water."

As for boat ramps, the Bullfrog Main Ramp Spur is still closed for safety reasons because it is being used as a construction zone for dismantling dilapidated components of the Dangling Rope Marina. It was previously announced that the park would re-open this ramp to small, motorized vessels (25 feet or less) and become the takeout for Colorado River runners when lake levels reached 3,540, but that is being delayed. Until further notice, all motorized vessels and Colorado River rafters are asked to continue using the Bullfrog North Ramp.  

On the southern end of Lake Powell, the Stateline Auxiliary Ramp remains operable 24 hours a day, seven days a week to motorized vessels of all sizes. Barring unforeseen circumstances, the park believes the bathymetry at this ramp will ensure sustainable, long-term motorized vessel access to south Lake Powell.  

The Antelope Point Marina Business Ramp: This ramp is open for all vessels, including houseboats. Interested customers should contact Antelope Point Guest Services to inquire about their specific vessel(s), 928 645-5900 ext. 5032.     

Due to the complex mix of factors that affect Lake Powell’s water levels, Lake Powell boaters are asked to please be aware that it will not be known when the lake reaches a certain water level until it occurs. Information about Lake Powell marina services and water level statistics are available 24/7 at this website.
