Background reading: Sebago Lake on Wikipedia
Sebago Lake covers about 28,911 acres in Cumberland County, Maine and is classed as a natural lake. The surface sits about 269 ft above sea level and the deepest point is roughly 315 ft down.
We read the level from USGS gauge 01063995, listed as Sebago Lake near North Windham, Maine. 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.
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.
