About Lake Sammamish

Lake Sammamish is a 4,893-acre natural lake in King County, Washington. The surface sits about 30 ft above sea level and the deepest point is roughly 115 ft down.

Water level on this page comes from USGS gauge 12122000 (Sammamish Lake near Redmond, 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.

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.
