Dillon Reservoir, often called Lake Dillon, is a prominent man-made lake in Summit County, Colorado. Sitting at approximately 2,750 meters (9,030 feet) elevation, it impounds the Blue River below Dillon Dam and serves as a key water supply and recreation hub for the region. Visitors come for paddle sports, fishing for trout, and docking services; the shoreline features parks, trails, and access points for day trips and overnight stays. Its proximity to Breckenridge, Frisco, and Silverthorne makes it a gateway for alpine biking, sightseeing drives, and year-round outdoor activities.
