The Enloe Dam, also known as the Similkameen Dam, and its powerplant are located on the Similkameen River about 4 miles (6.4 km) west-northwest of Oroville, Washington. Located just above Similkameen (Coyote) Falls, the concrete arch-gravity dam stands about 54 feet (16 m) high, with a crest length of about 290 feet (88 m), built between 1916 and 1923. The dam was named after the president of the Okanogan Valley Power Company, Eugene Enloe. The dam was operated to generate power at its powerplant, located about 850 feet (260 m) downstream from the dam.[2] Lacking fish ladders, Enloe Dam blocks fish passage and completely extirpated anadromous fish migration into the upper reaches of the Similkameen River and its tributaries in Canada.[3]
