DescriptionRedridge Steel Dam HistoricalMarker DSCN2198.JPG |
The Michigan Historic Civil Engineering Landmark Marker at the Redridge Steel Dam, a steel dam across the Salmon Trout River in Redridge, Houghton County, Michigan. Completed in 1901, it is a flat slab buttress dam constructed of steel, a relatively rare material for construction of dams, which are typically earthenworks or masonry. Most sources indicate it was one of only three such dams constructed in the United States, the other two being the Ashfork-Bainbridge Steel Dam (1898, Arizona) and the Hauser Lake Dam (1901, Montana), the last of which failed within a year of construction. The dam was taken out of service and the impounded lake released. |
