Background reading: Cougar Reservoir on Wikipedia
Cougar Reservoir covers about 1,130 acres in Oregon and is classed as a reservoir.
We read the level from USGS gauge 14159400, listed as Cougar Lake near Rainbow, OR. 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.
It is big enough for a proper sail but small enough that waves rarely get serious. Gusts off the shoreline are usually the bigger story than wave height. 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.
The National Weather Service forecast for the lake from October 26: Monday: SSW wind 4 to 5 kt, gusts to 9 kt, high near 49°F, 100% chance of rain.
