Background reading: Surry Mountain Lake on Wikipedia
Surry Mountain Lake is a 353-acre reservoir in New Hampshire.
Water level on this page comes from the U.S. Army Corps of Engineers reading at Surry Mountain Dam, published through the Corps' CWMS data service. Wind, gusts and rain come from the National Weather Service forecast grid that covers the water.
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.
