Koma Kulshan Project
Located in the Mount Baker National Forest, it is one of six Federal Energy Regulatory Commission (FERC)-licensed small hydro installations on Federal Government land in Washington state.
Koma Kulshan is the name of Mount Baker in the Lummi dialect.
Dams
Intakes are located at diversion dams on the Rocky Creek and Sulphur Creek tributaries of Lake Shannon. A 42–45-inch (1,100–1,100 mm) diameter, 19,250-foot (5,870 m) long penstock carries water from a bifurcation (48°41′29″N 121°47′31″W / 48.6914°N 121.7919°W, 2,750 feet (840 m) a.s.l.) to the powerhouse. Water is discharged from the powerhouse through a short run on Sandy Creek to Baker Lake. Up to 120 cubic feet per second (3.4 m/s) is diverted to the powerhouse.
Rocky Creek Dam (48°41′06″N 121°48′23″W / 48.6849°N 121.8065°W) is 18 feet (5.5 m) high, 32 feet (9.8 m) long at 2,770 feet (840 m) a.s.l.
Sulphur Creek Dam (48°41′34″N 121°47′34″W / 48.6928°N 121.7928°W) is 15 feet (4.6 m) high, 37 feet (11 m) long at 2,755 feet (840 m) a.s.l.
Diversion of the creek affected the appearance of Upper and Middle Sulphur Creek Falls.
Peak generation
Power generation peaks in May through July coinciding with snowmelt, and has a smaller peak in November coinciding with the wet season.
