Otter Brook Lake is a 84-acre reservoir in Cheshire County, New Hampshire.
Water level on this page comes from the U.S. Army Corps of Engineers reading at Otter Brook Dam, published through the Corps' CWMS data service. Wind, gusts and rain come from the National Weather Service forecast grid that covers the water.
On water this size, waves stay small even on windy days. The catch is gusts: shoreline terrain funnels the wind into sharp puffs that catch out small boats and paddlers. 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.
