Loud Dam, Hydroelectric dam in Iosco County, Michigan, US.
Loud Dam is a concrete structure with earthen embankments that spans the Au Sable River, creating a reservoir of about 937 acres. The facility was built to generate electricity and continues to serve that purpose today.
The dam was completed in 1913 by Consumers Power Company and named after Edward F. Loud, a prominent figure in Michigan's lumber industry. It was part of the early development of hydropower in the region.
This dam serves as a critical checkpoint during the annual Au Sable River Canoe Marathon, where paddlers navigate through a series of water management structures. The event has made this location well-known among the paddling community.
Two portage routes allow water enthusiasts to bypass the dam: a gravel path of about 250 yards with a canoe slide and a shorter but steeper alternative. Visitors should choose based on their skill level and available time.
The facility uses two horizontal Allis-Chalmers turbines to generate power, which surprises many visitors who expect modern equipment. This older technology still operates efficiently and reflects the heritage of early hydropower development.
