Background reading: Harry S. Truman Lake on Wikipedia
Harry S. Truman Lake is a 49,366-acre reservoir in Missouri.
We read the level from USGS gauge 06922440, listed as Harry S. Truman Dam and Res. at Warsaw, MO. Wind and weather come from the National Weather Service grid cell over the lake, so the numbers describe open water rather than the nearest airport.
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.
