Keechelus Lake

Keechelus Lake () is a lake and reservoir in the northwest United States, near Hyak in Kittitas County, Washington. Approximately fifty miles southeast of Seattle and a few miles southeast of Snoqualmie Pass, it is the source of the Yakima River.

Keechelus Lake is the westernmost of three large lakes near Interstate 90 and north of the Yakima River in the Cascade Range; the other two are Kachess Lake in the middle and Cle Elum Lake to the east. After crossing nearby Snoqualmie Pass at an elevation of 3,020 feet, Interstate 90 runs along the lake's eastern shoreline and tight against mountains. Its westbound lanes included a snowshed midway; built in 1950 for U.S. Route 10, it was removed in April 2014.
