Fish Slides, Anyone?

Elevators and water slides for fish may sound straight out of Dr. Seuss—but they actually exist in Michigan. Listen up:

Sturgeon go back to their home river to spawn. And for half the sturgeon in Lake Michigan, that means the Menominee River.

But hydroelectric dams block the river, forcing the fish to lay their eggs in less protected waters close to the lake. Only about 10 percent of the young survive.

Denny Caneff of the River Alliance of Wisconsin says the fish needed a creative solution.

“No one’s going to move those dams,” he says. “So the project called for literally building an elevator to get them upstream, and water slides to get them down stream.”

With access to better spawning grounds, biologists expect the sturgeon population in Lake Michigan to, ahem, be elevated by more than 20,000 in the next 40 years.
