Prompton Lake covers about 290 acres in Wayne County, Pennsylvania and is classed as a reservoir.
We read the level from USGS gauge 01428900, listed as Prompton Reservoir at Prompton, 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.
