river rising in Wasatch county, north-central Utah, U.S. It flows about 70 miles (110 km) east to join the Duchesne River 19 miles (31 km) east of Heber (Heber City). Strawberry Dam (1913), near the river's source, created Strawberry Reservoir, a project that pioneered the diversion of water from one Utah watershed to another for irrigation. Strawberry Dam was decommissioned and breached in 1985, when the reservoir, administered by the Central Utah Water Conservancy District, was enlarged to a total surface area of about 17,164 acres (6,946 hectares).
