Midview Dam and Dike form a 5,800 acre-foot capacity, offstream reservoir about 12 miles east of Duchesne, Utah. The dam is an earthfill, rockfaced structure, 54 feet high, with a volume of 139,000 cubic yards. The dike of similar construction, has a structural height of 21 feet, a crest length of 2,575 feet and a volume of 86,000 cubic yards.
MidView Dam and Dike are part of the Moon Lake Project is in northeastern Utah on the north side of the Duchesne River about 140 miles east of Salt Lake City, Utah. The facilities of the project include Moon Lake Dam on the West Fork of the Lake Fork River; Yellowstone Feeder Canal extending from the East Fork of Lake Fork also known as the Yellowstone River, easterly to Cottonwood Creek, a tributary of the Uinta River; Duchesne River Exchange, involves water diverted from the Duchesne River and used by exchange with other rights as a supplemental supply to irrigate the lands owned by stockholders of the Moon Lake Water Users Association. The water rights of approximately 8000 acres in the Lower Lake Fork River area are the basis for this venture. This exchange supplies the Moon Lake Project with more than 20,000 acrefeet per year. This is accomplished by the Midview Dam and Dike which form an offstream reservoir; Midview Lateral which connects Midview Reservoir with the lower Lake Fork area; and the Duchesne Feeder Canal which carries water to Midview Reservoir and the Lake Fork River. The project provides supplemental irrigation water for 75,256 acres of land in Duchesne and Uintah Counties plus 10,000 acres under the Midview Exchange.
