Sugar Loaf Dam is a dam in Lake County of mid-Colorado, 4 miles (6.4 km) west of Leadville. It has a height of 135 feet (41 m) feet and is over 2,000 feet (610 m) long at its crest, impounding the Lake Fork of the Arkansas River near its headwaters. The earthen dam was one of five reservoir dams completed from 1965 to 1968 by the United States Bureau of Reclamation as part of the larger water diversion project named the Fryingpan-Arkansas Project. The project was authorized in 1962 by President Kennedy and was completed in 1981. The Fry-Ark diverts water across the continental divide from the Colorado River basin. This water is delivered to the more arid plains east of the Rocky Mountains. Although the predominant use is agricultural, some water is available to several cities east of the continental divide, including: Colorado Springs, Pueblo, La Junta, Lamar. Water is diverted from the West Slope's Fryingpan River basin through a series of interconnected tunnels and small diversion dams into the Charles H. Boustead Tunnel. The Boustead runs water underneath the Continental Divide 5.5 miles (8.9 km) before discharging it into Turquoise Lake. Water then leaves Turquoise Lake via the Mt. Elbert Conduit, which runs nearly 11 miles (18 km) to the Mt. Elbert Forebay, then dropped down over 0.5 miles (0.80 km) in elevation to the hydro-electric Mt. Elbert Power Plant.Turquoise Lake is the reservoir created by the dam. It has a surface area of 1,780 acres (720 ha) and a capacity of 129,440 acre-feet (159,660,000 cubic meters). The lake and its surrounding land provide various recreational activities for visitors in both the summer and winter.

The Mineral Belt National Recreation Trail is an 11.6 mile all-season biking/walking trail that loops around Leadville, Colorado and through its historic mining district. The trail's setting is quintessentially Colorado Rocky Mountain landscape. Groves of aspen, conifer forests, wildflower meadows, and open vista sage parks are interspersed with once-booming mine sites. Ever-present views of the Sawatch and Mosquito mountain ranges provide perspective and a sense of permanence to the area. Several signs along the way provide historical snippets about Leadville's colorful past. The trail is designed for bicycles, longboards, walkers, wheelchairs, strollers and in-line skaters. When the snow falls, snowcats groom the trail to provide access to Nordic skiers, snowshoers and winter-bikers. About six miles of this trail meanders through the historic Leadville Mining District. In part the trail follows old mining-camp railbeds. "What makes this trail unique is that it goes through one of the greatest mining districts in the world," says Lake County, Colorado Assessor Howard A. Tritz, an original member of the group which spearheaded trail development. "It has some of the best scenery anywhere, and it's accessible and available to everyone, visitors and locals alike, regardless of age or ability."
