Background reading: Swift Reservoir on Wikipedia
Swift Reservoir covers about 4,621 acres in Washington and is classed as a reservoir. The reservoir dates to 1956. The water surface sits about 1,010 ft above sea level.
Water level on this page comes from USGS gauge 14217599 (Swift Reservoir 3.2 Mi East Of Dam near Cougar, WA), about 3 mi from the middle of the lake. Wind, gusts and rain come from the National Weather Service forecast grid that covers the water.
Mid-sized lakes like this one tend to have shifty, gusty wind near shore and steadier pressure in the middle, which is why gust spread matters as much as average speed. 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.
