Background reading: Fort Supply Lake on Wikipedia
Fort Supply Lake covers about 1,692 acres in Oklahoma and is classed as a reservoir.
Water level on this page comes from the U.S. Army Corps of Engineers reading at Ft Supply Lake, published through the Corps' CWMS data service. Wind, gusts and rain come from the National Weather Service forecast grid that covers the water.
It is big enough for a proper sail but small enough that waves rarely get serious. Gusts off the shoreline are usually the bigger story than wave height. 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.
