Lake Powell water levels continue to drop. Glen Canyon National Recreation Area (GCNRA)announced Friday that Stateline Launch Ramp is closed. GCNRA said weekend boaters launching and retrieving May 15 and 16 do so at their own risk.
The ramp was closed to motorized vessels Monday and will remain closed until further notice. The closure is attributed to revised water level projections by the Bureau of Reclamation (BOR).
GCNRA said, “The Stateline Launch Ramp will remain open to non-motorized vessels (e.g., canoes, kayaks, and paddleboards). Owners of non-motorized watercraft are advised to clean, drain, and dry their equipment to remove quagga mussels.”
BOR said lake levels are dropping faster than previously predicted. On May 12, the Stateline Launch Ramp had approximately 3 feet of water depth ending at around 3558 elevation. According to Lake Powell Water Database, the absolute minimum water elevation required for Wahweap Launch is 3,556.
Total inflow to Lake Powell so far in 2021 is just under 2 million acre-feet. Total outflow is well over 5-million acre-feet. The lake is about 140 feet below ’Full Pool.’
GCNRA said, “Boaters are asked to avoid the fenced construction zone located on the north side of the Stateline Launch Ramp. The construction zone is a staging area to assemble dock sections to be barged to Dangling Rope for replacement of that dock system. A wide-load barge will depart from the Stateline Boat Ramp May 17 between 6:30 and 7:30 a.m. and travel slowly to Dangling Rope. The wide load should travel through the Antelope Marina area between 8:30 and 10 a.m., and all boaters are asked to please use caution going through the Marina at that time.”
The Stateline Launch Ramp is at the Utah-Arizona border off Highway 89 between Page and Greenehaven.
GCNRA warns, “The park’s busy season is underway, and visitors are advised to expect congestion and exercise caution in all visitor use areas. Dangers of the spring season require park visitors to monitor changing weather conditions and lake levels. Always approach the shore with caution and watch for shallows and submerged debris.”
