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.[1][2] Byllesby, a former employee of both Edison and Westinghouse, formed what would become Northern States Power in 1909.[3]

The dam created Lake Byllesby, 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 Dakota County.
