Researchers are starting a 10-year project to keep so-called “vampire fish” out of Michigan rivers.

Over the last 20 years, three dams have been removed along the Boardman-Ottaway River in a massive effort to restore the river, according to Michigan State University. The only one that’s left is the Union Street dam in Traverse City, standing between the river and Lake Michigan

The dam is aging and has had unintended consequences on native wildlife, but it can’t just be removed. Doing so would allow invasive species like sea lampreys and others into the river, making it much more difficult and expensive to try to control those populations.
