Madison in Dane County, Wisconsin — The American Midwest (Great Lakes)
Tenney Park Lock and Dam
The first dam was built of earth in 1847 by Leonard J. Farwell, later a Wisconsin governor. The dam enlarged Lake Mendota and increased its depth. Prior to construction Mendota's water level was only slightly above Monona's, and the Catfish (Yahara) River meandered through connecting marsh.
Site of the first dam was South of the present lock and a large flour mill was built over the outlet. Torrential thunderstorms destroyed the original dam on April 4, 1866. Despite great controversy it was reconstructed.
In 1896 Madison City purchased Tenney Park site, built a boat lock, and used concrete to improve the dam. Controversy rose again in 1900 when riparian owners whose land was flooded sought removal of the dam. Their suit failed in the courts. The present lock was built by Madison City in 1959 and maintains a water level five feet above Lake Monona.
Erected 1967 by Dane County Historical Society. (Marker Number 10.)
