Rimrock Lake is a lake along the course of the Tieton River, in Yakima County, Washington state, USA.

The lake is used as a storage reservoir for the Yakima Project, an irrigation project run by the United States Bureau of Reclamation. An impoundment of the Tieton River, Rimrock Lake's capacity and discharge is controlled by Tieton Dam, a 319 foot (97 m) high structure built in 1925. Rimrock Lake's active capacity is 198,000 acre feet (244,000,000 m³). [http://www.usbr.gov/dataweb/html/yakima.html Yakima Project] , United States Bureau of Reclamation.]

About 8 miles (13 km) downstream from Rimrock Lake the Tieton River is tapped by the Tieton Diversion Dam, supplying water to the Tieton Main Canal. The canal supplies irrigation water to the Tieton Division of the Yakima Project, with excess and agricultural runoff draining into Ahtanum Creek, west of Yakima.
