The Francis H. Clergue Generating Station is a three-unit hydroelectric station located at the outlet of Lake Superior on the St. Marys River. It was originally built in 1916 but was redeveloped in 1981 for electricity generation. It has an installed capacity of 52.0 MW and a head of 5.9 metres. Water flows from the reservoir through three tunnels or penstocks, which generate approximately 385,381 MWh of renewable energy per year. The swirling water that you can see from the shore is called the tailrace. This is water that has flowed through the turbine to generate electricity, and is now joining the main flow the river.
