Dillon Reservoir

Dillon Reservoir spans 3,233 acres with 27 miles of shoreline, nestled between the towns of Dillon, Frisco, and Silverthorne in Summit County, Colorado.

The Denver Water Board constructed the dam in the 1950s, requiring the complete relocation of the original town of Dillon which now rests beneath the water.

The reservoir functions as a central gathering point for sailing enthusiasts through the Dillon Yacht Club, which coordinates multiple summer racing events.

Between June and September, visitors can rent boats at Dillon Marina or Frisco Bay Marina, while fishing remains available throughout the year from shore or vessel.

The reservoir supplies 40 percent of Denver's water through the Harold D. Roberts Tunnel, which carries water under the Continental Divide to the South Platte River Basin.
