Dillon and Silverthorne

Lake Dillon sits at almost 2 miles high in the Rocky Mountains. The dam and reservoir that produced this Summit County resort, along with Dillon Village on its shore and the town of Silverthorne just below it, are collectively one of Colorado's winter-summer fun destinations. Dillon Dam is 5,288 feet long by 231 feet high, creating a large freshwater source for the city of Denver, as well as 25 miles of scenic shoreline. The dam stores 85.5 billion gallons of water from the Snake and Blue Rivers and Ten Mile Creek. On cue, these waters rush eastward to the South Platte River Basin through the Transmontane Project, or Roberts Tunnel--augered hundreds of feet under the Continental Divide in one of the West's most controversial water relocation epics. Today Dillon, Silverthorne, and the Blue River Basin on Colorado's western slope see their share of sailboating, snow and Nordic skiing, windsurfing, and snowboarding.
