dam removal

In the state of Michigan, chances are good that if you live near a river or stream, you also live near a dam. There are nearly 2,600 dams in Michigan. Many of them are small and privately owned. And nearly all of them are getting old.

According to 2014 report, 90% of Michigan’s dams are going to meet or exceed their design life — the length of time for which they were designed to operate — by 2020. Beyond that design life, the dams become increasingly likely to fail. That can lead to catastrophic flooding, erosion, and the spread of toxins trapped behind the dam.

So why were all of these dams constructed in the first place?
