Sheridan Lake: Flume Trailhead #50

The Flume Trail follows the bed of the historic Rockerville Flume, an 1880s engineering feat that carried water 20 miles from Spring Creek to the placer gold diggings near Rockerville. Designated a National Recreation Trail for its historical significance, it traces the actual flume route for much of its length, passing tunnels, trest" remains, and artifacts left from the mining boom. The trail runs roughly 11 to 13 miles point-to-point between Sheridan Lake and Rockerville, with the Calumet Trailhead at Sheridan Lake's southeast shore the most popular access. Highlights include two flume tunnels about a half-mile below the dam (bring a flashlight for the long one), the lakeside stretch along Sheridan Lake, Spring Creek Canyon, and Boulder Hill's wide views of the eastern Hills, plains, and Badlands. A three-mile Spring Creek Loop offers a shorter option. Because the artifacts are fragile, this is a foot-traffic-only trail. The grade is gentle where it follows the flume, though some bypass sections are rougher. Foot traffic only.
