Spearfish Creek originates in the upper elevations of the Black Hills National Forest. The creek flows in a generally northern direction through coniferous/mixed forest before entering the 20-mile-long Spearfish Canyon. The Spearfish Project is located at the lower end of the canyon.
The Spearfish Project consists of the 130.1-foot-long, 4-foot-high concrete Maurice Dam, which impounds a 0.32-acre reservoir with a crest elevation of 4,381 feet United States Geological Survey mean sea level. The dam has a concrete sill section, two stop-log sections, a trashrack, and an intake structure that leads to an approximately 24,000-foot-long, 6.6-foot-wide, and 9-foot-high underground concrete aqueduct, which empties into a forebay pond.
Until 2008, the City of Spearfish had been operating this 4.0 MW project without a FERC license. The project operates in a run-of-river mode.The project is located on the Spearfish Creek in Lawrence County, South Dakota and occupies 57.26 acres of federal lands within the Black Hills National Forest.
