1910s is when the turbines were installed, 1980s is when they were converted from mechanical power to electrical generation.

"The Little Quinnesec hydro facility is a 9,100-kilowatt hydroelectric generating station in the town of Niagara, Wisconsin. It was originally built to power a pulp and paper mill that operated on the site from the 1898 through 2012. The station contains six total units. Five of the units are horizontal, double-runner Francis turbines that were installed between 1900 and 1911 to provide mechanical power for pulp grinders. Motors were added between 1920 and 1960 to provide supplemental power to the grinders. In the 1980s, the grinders were removed, and the motors were reconfigured as generators and have produced electrical power since then. The sixth unit is a vertical Francis turbine installed in 1916 to provide electrical power to the mill. Since 2009, all electrical power has been delivered into the regional electrical transmission grid." |
The 1916 unit used a vertical shaft because
thrust bearings made horizontal shafts obsolete. Those thrust bearing notes have diagrams of how the horizontal shaft turbines worked.

The truss bridge in the background of the above screenshot was for a C&NW industrial spur to the pulp and paper mill. I can't tell if it is a pin-connected truss.

I had assumed that the truss bridges in the left background of the above screenshot carried the industrial spur. But the screenshot below indicates that they might be carrying pipes.
Jason found a better angle.
