Prairie du Sac Hydroelectric Generating Station Tours

2015 public tours to take place May 15 - 17

In 2014, Alliant Energy celebrated the 100th anniversary of the Prairie du Sac Dam. Over 900 people toured the dam, but we received more tour requests than we could meet!

As a result, the utility is partnering again with the Sauk Prairie Area Historical Society to offer public tours of the dam in May.
