Changing Lake Levels Update
May 19, 2023
Dear Partners:
The park is pleased to announce that due to a high snowpack, a higher spring runoff continues to affect Lake Powell water levels. The lake level has been rising approximately one foot per day. As of May 19, Lake Powell’s elevation is 3543.3 feet (above sea level). An overview is available of projected water levels and potentially concurrent re-opening of visitor access points at this link: Higher Lake Powell Water Levels Expected for 2023 Boating Season - Glen Canyon National Recreation Area (U.S. National Park Service)
1. Spring Run-off Debris: Due to the spring runoff, the San Juan and Colorado Rivers are experiencing a large amount of debris flow. Boat operators need to use extreme caution while navigating the lake, as large debris is present. 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.
2. North Lake Powell - Bullfrog Main Ramp Spur: This ramp is 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 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 3540, but that is being delayed. Until further notice, all motorized vessels and Colorado River rafters are asked to continue using the Bullfrog North Ramp.
3. South Lake Powell – Stateline Auxiliary Ramp: This ramp remains operable 24/7 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.
4. South Lake Powell – 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: Changing Lake Levels - Glen Canyon National Recreation Area (U.S. National Park Service). Before heading to the lake, boaters should check the park’s website for the status of their preferred launch/retrieval destination.
