Kachess Lake, Reservoir in Kittitas County, United States
Kachess Lake spans 9.6 miles in length and 1.2 miles in width, reaching depths of 430 feet within the Cascade Range mountains.
The Kachess Dam, constructed in 1912 as a 115-foot earthfill structure, transformed this water body into a storage reservoir for the Yakima Project.
The name Kachess comes from Native American language meaning 'more fish', reflecting the water's historical abundance of aquatic life.
The lake maintains year-round fishing access with specific regulations including a 10-fish limit for kokanee and two trout minimum size of 14 inches.
During summer months, the water level decreases substantially due to reservoir drawdown, affecting boat launching capabilities at regular facilities.
