Estabrook Falls Fish Passage Construction Update
Exciting changes are coming to the Milwaukee River! Construction on the Estabrook Falls Fish Passage Project is beginning. This important project will modify Estabrook Falls—a man-made barrier left behind from historic bedrock mining—to help native fish like northern pike and lake sturgeon move upstream to reach vital spawning habitat. Watch the video below to learn how this effort will support a healthier, more connected river system.
Construction is expected to run from late Spring through Fall 2025. As part of the construction please plan for:
-
- -Temporary weekday closures of the west side trail of the Milwaukee River
- -Weekday river closures.
Please plan ahead and watch for posted detours.
Thank you for your patience as we work to restore fish passage in the Milwaukee River!
Fish Passage Construction
Trail Closure Location
The Estabrook Falls Fish Passage Project is an important effort to help native fish, like northern pike and lake sturgeon, move upstream to reach vital spawning and nursery habitat. These native fish are weak jumpers and can’t make it past barriers like Estabrook Falls, which is not a natural waterfall but a leftover feature from historic bedrock mining. While fish can occasionally pass during very high river flows, the falls typically act as a significant barrier. Estabrook Falls is currently the largest remaining barrier to fish passage in the lower Milwaukee River. This project will modify the falls to improve year-round fish movement and support a healthier, more connected river system.
