About Rhinelander

The primary purpose of Rhinelander is hydroelectric. The dam generates hydroelectric power by channeling water through turbines, converting the energy of flowing water into electricity. The dam is owned by Rhinelander Paper Co (private). It impounds the Wisconsin River near Rhinelander.
