Background reading: Brownlee Reservoir on Wikipedia
Brownlee Reservoir covers about 13,881 acres in Washington County, Idaho and is classed as a reservoir.
Water level on this page comes from the U.S. Army Corps of Engineers reading at Brownlee Dam, published through the Corps' CWMS data service. Wind, gusts and rain come from the National Weather Service forecast grid that covers the water.
With this much open water, waves build quickly when the wind lines up with the long axis of the lake. Pick a launch on the upwind shore on breezy days and the ride home is easier. 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.
