Redridge Dam

Industries, Engineering, Charles Karhkainen on rope block and Reino Alanen in hole, try to open old valves at the pipes underneath the steel dam at Redridge. After several days of hard and hagardous work, the men and the company gave up. It was impossible to break open the huge rusted valves that had been in stalled in 1901-1902 when the dam was built. The dam (steel) was built by the Wisconsin Iron and Foundry Works of Milwaukee.

Redridge Dam

Industries, Engineering, Grates over the valves in the steel dam at Redridge gave some protection from floating debris from blocking the pipes, but eventually the valves resuted and broke and debris did get through and create problems. Notice one valve rod broken. The steel dam was finally lowered to a point where the exit was equal to the river's run off. The water level was dropped in the summer of 1955. The log dam still impounds river water.

Redridge Dam

Industries, Engineering, The clutterred up "gates" to the spillway of the Redridge Steel Dam that impounded the waters of the Salmon Trout River to supply water to both the Atlantic Mine and the Baltic copper mills. The spillway of "launder" was built in 1902, torn apart by spring floods in 1905 and then rebuilt with a concrete base. The logs are piled up due to a log boom tied with cables across the gateway. Picture faces north toward Lake Superior. Gates taken down in 1966.

Redridge Steel Dam

Industries, Engineering, Water Notice for any researcher, --the walkway over the pillway of the logdamin the right background. Also notice the rail tracks down below the dam and running paralell to the upper tracks. This lower track connected with the upper track by a witch near the old Club House north gate (NOT the east gate). In those days railroad tracks seemed to be everywhere, and the miniature locomotives spewed hot cinders that each fall started many forest fires.

Redridge Steel Dam

Industries, Engineering, Water The valve and launder that lead from the log dam across the Salmon Front River at Redridge is shown here as it neared the steel dam. At that point a large hol was cut in the steel to permit the water through to another launder that took it to the Atlantic Mill at Redridge. Water for the Baltic Mill was piped by two five foot diameter pipes to the Baltic Mill. The Atlantic Mill closed in September 1912, the Baltic closed in Sept. of 1922.
