Background reading: Onondaga Lake on Wikipedia
Onondaga Lake is a 2,965-acre natural lake in Onondaga County, New York. The surface sits about 361 ft above sea level and the deepest point is roughly 62 ft down.
We read the level from USGS gauge 04240495, listed as Onondaga Lake at Liverpool NY. 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.
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.
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.
