Reading from Oct 26, 2026. Shaded band: range of October averages on record; dashed line is the typical level.
Tionesta Lake was at 1,088.52 ft on October 26, falling 1.01 ft over the past week. That is well below normal for October: the typical October level is 1,090.30 ft, so the lake is 1.78 ft below its usual mark.
Tionesta Lake covers about 524 acres in Franklin County, Pennsylvania and is classed as a reservoir.
We read the level from USGS gauge 03019500, listed as Tionesta Creek Reservoir at Tionesta Creek Dam, 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.
Small lakes rarely build big waves, but trees and hills around the shore make the wind patchy. Expect sudden puffs and lulls rather than a steady breeze. 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.
