McPhee Reservoir is named for McPhee, Colorado, a company town founded by the New Mexico Lumber Company that is now submerged under the reservoir. In 1927, the McPhee sawmill produced over half of Colorado's lumber. The town housed up to 1,500 employees. The sawmill closed in 1946.^[2]

The lake itself may be accessed from near Dolores, Colorado, by state highways 145 and 184, and offers various boat-launching facilities, picnic areas, and campgrounds in the McPhee Recreation Area operated by the U.S. Forest Service. The lake fills the lower end of the Dolores Valley, with the dam^[3] completed in 1985 across Dolores Canyon.

A hydroelectric powerplant operates at the dam. Called the McPhee Dam Powerplant, it uses two turbines to power a 1,300 kilowatt generator. The plant produces 7,170,000 kilowatt-hours annually.^[4]
