Dillon Reservoir is a big, beautiful lake in Summit County, the heart of the Colorado Rocky Mountains. Looking at this you can see why there are so many resort towns around it.

Completed in September 1963, Dillon Reservoir is the Denver Water system's largest water storage facility. Before the dam could be built and the lake filled, the entire town of Dillon, Colorado, and a hydroelectric plant on the river had to be relocated. The project diverts water from the Blue River Basin into the South Platte River Basin through the Harold D. Roberts Tunnel beneath the Continental Divide. Dillon Dam is an earth-fill dam, 5,888 feet long by 231 feet above the stream bed of the Blue River. Dillon Reservoir's surface area averages 3,233 acres and its' 26.8 miles of shoreline support recreational activities of all sorts.

The Frisco Bay and Dillon Marinas host several regattas and other special events during the summer months. Fireworks shows over the lake highlight the Fourth of July and the annual winter Gold Rush celebrations in Frisco.
