Background reading: Lake Washington on Wikipedia
Lake Washington covers about 21,745 acres in King County, Washington and is classed as a natural lake. The surface sits about 16 ft above sea level and the deepest point is roughly 214 ft down.
Water level on this page comes from the U.S. Army Corps of Engineers reading at Kenmore Lake Washington, 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.
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.
