Completed in September 1963, Dillon Reservoir is the largest water storage facility in the Denver Water system. Building the dam required relocating the entire town of Dillon, Colorado, and a hydroelectric plant. The project diverts water from the Blue River Basin through the Harold D. Roberts Tunnel under the Continental Divide into the South Platte River Basin. Dillon Dam is an earth-fill dam, 5,888 feet long by 231 feet above the Blue River stream bed. Dillon Reservoir's surface area of 3,233 acres and 26.8 miles of shoreline support many recreational activities.
Getting There: From Denver take Interstate 70 through the Eisenhower Tunnel to Dillon. To access the Dillon Marina, take Silverthorne exit 205 to Hwy 6 and take Hwy 6 to Dillon. Follow the signs to the marina. To access the Frisco Bay Marina, take the Frisco exit 203 to Hwy 9. Take Hwy 9 to Main Street and turn left (east) to the marina.
