Dillon Reservoir Recreation Area – Dillon and Frisco, CO | Biking, Boating, Camping, Fishing, Hiking on Lake Dillon in Summit County

The Dillon Reservoir, also known as Lake Dillon, is one of Summit County’s biggest draws, encompassing around 3,233 surface acres of water and a shoreline of nearly 27 miles. It’s surrounded by Dillon and Frisco on either side, with Silverthorne sitting just below the dam.

The Denver Water Board voted to build a dam in the Rockies to secure water for the Front Range in the late 1950s. The Old Town of Dillon actually sits at the bottom of Lake Dillon, so there really is an underwater ghost town in Summit County.

The Dillon reservoir supplies water for the City of Denver. It’s owned and operated by Denver Water, which is Colorado’s largest public water company. The U.S. Forest Services manages the surrounding campgrounds, which reside within the White River National Forest. Water sports are the main draw of Lake Dillon.
