Reading from Oct 26, 2026. Shaded band: range of October averages on record; dashed line is the typical level.
Cowanesque Lake was at 1,080.34 ft on October 26, holding steady over the past week (-0.03 ft). That is near normal for October: the typical October level is 1,080.27 ft, so the lake is 0.07 ft above its usual mark.
Cowanesque Lake covers about 1,079 acres in Tioga County, Pennsylvania and is classed as a reservoir.
We read the level from USGS gauge 01519995, listed as Cowanesque Lake at Lawrenceville, PA. 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. 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.
