Hydro Power

Hydro Power

This article was written in 1982, when rehabilitating many retired hydropower sites was being given consideration in Minnesota. In fact, very few sites have had hydropower reinstalled because of the poor economic viability of the sites that were considered and the potential negative environmental impacts that new hydropower stations would have on our Minnesota rivers. In Minnesota, and in the nation, the trend now (largely because of the impact hydropower has on the river system) is to remove old mill dams rather than reconstruct the dams for hydropower. One purpose for including this article on the internet is to illustrate how knowledge and policies can change over the years.
