Saint Marys Falls Hydropower Plant

Saint Marys Falls Hydropower Plant – a very interesting area if you ever get up there. Lots to see from museums to ships. We loved our tour of the area.

Tucked beside the mighty Soo Locks, the Saint Marys Falls Hydropower Plant quietly channels the force of the St. Marys River into clean energy. Built in 1902, this graceful red-brick structure is one of the oldest operating hydro plants in the United States. Its 74 turbines once powered the locks and local industries, and today it still produces electricity for the region—more than a century later.

Standing along the riverbank, you can feel the deep hum of water rushing beneath the arches, where engineering and nature meet. It’s a reminder of how innovation and the Great Lakes have long worked together to move both ships and people forward.
