Byllesby Dam (Minnesota)
Lake Byllesby Dam is a concrete gravity dam located in Randolph Township, Dakota County and Stanton Township, Goodhue County, Minnesota in the southern part of the state, just west of the city of Cannon Falls.
The 75-foot (23 m)-high dam was built in 1910 by H.M. Byllesby & Company to impound the Cannon River for hydroelectric power. Its nameplate capacity is 1.8 MW. Byllesby, a former employee of both Edison and Westinghouse, formed what would become Northern States Power in 1909.
The dam created the Lake Byllesby Reservoir, with a surface area of 1,432 acres (580 ha) and a capacity of 20,000 acre feet (25,000,000 m3). The facility is owned and operated by a partnership of Dakota and Goodhue counties. The Lake Byllesby Regional Park stands on the northeastern shore. Other recreational facilities include a campground and a sand beach.
