Lake beaches and swimming lakes in Washington

This guide covers 45 lakes and reservoirs across Washington. 34 of them are reservoirs held back by a dam and 11 are natural lakes. Lake Sacajawea is the biggest, covering roughly 837,440 acres. The deepest water on record here is at Lake Chelan, about 1,486 feet. Rivers that feed or drain them include the Columbia River, the Lewis River and the Baker River. 16 of these lakes have a public gauge, so their water level on this site is a real reading rather than an estimate. The agency behind the most lakes here is US Bureau of Reclamation (Yakima Project). Across the state we map 21 named swimming spots and access points from federal and state sources.
