Background reading: Lake Chelan on Wikipedia
Set in Chelan County, Washington, Lake Chelan is a 33,359-acre reservoir. The surface sits about 1,099 ft above sea level and the deepest point is roughly 1,486 ft down.
We read the level from USGS gauge 12452000, listed as Lake Chelan at Chelan, WA. 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.
