Background reading: Glendo Reservoir on Wikipedia
Glendo Reservoir is a 12,059-acre reservoir in Platte County, Wyoming. Its dam was completed in 1958, and the lake is operated by United States Bureau of Reclamation. The water surface sits about 4,652 ft above sea level.
Water level on this page comes from the U.S. Army Corps of Engineers reading at Glendo Dam & Reservoir, published through the Corps' CWMS data service. Wind, gusts and rain come from the National Weather Service forecast grid that covers the water.
On a lake this size the wind has miles of open water to work with, so a 15 kt breeze can stack up a steep chop in the main basin while sheltered coves stay flat. Reservoir levels move with releases and inflow, so ramps and beaches can change week to week. The water level page tracks that day by day.
The go or no-go calls above are a starting point, not a guarantee. Read how we score conditions, and always check local rules and posted warnings before you launch.
