Clinton Gulch Dam Reservoir is a reservoir in Summit County, Colorado near Fremont Pass. It supplies water for irrigation, municipal water supply, and snowmaking. Colorado State Highway 91 goes over the top of the dam.

Water from the reservoir makes its way to Tenmile Creek. It then flows through Dillon Reservoir and to the Blue River, from where it is distributed.

The reservoir was built in 1977 by the Climax Molybdenum Company, whose mine is located nearby at Fremont Pass. In 1992, Climax Molybdenum sold the reservoir to the Clinton Ditch & Reservoir Company, which has shareholders that include farms, municipalities in Summit and Grand counties, and several ski areas who use the water for snowmaking.

The dam, NID ID CO02093, is a 175-foot (53-meter) high earthen dam that can store up to 5,915 acre-feet (7,296,000 cubic meters) of water. It was built in 1977 and is 1,550 feet (470 meters) wide.

A hiking trail encircles the lake. Rated easy, the trail is 2.4 miles (3.9 kilometers) long and has an elevation gain of 230 feet (70 meters).

The reservoir also offers fishing, including ice fishing in the winter. It is stocked with cutthroat trout, and rainbow and brown trout can also be caught.
