Lake sturgeon have been around for more than 130 million years, long before the Great Lakes formed. Commercial fishing in the 19th century, followed by damming rivers, nearly wiped out the species in the Milwaukee River basin.
A breeding and release program led by Riveredge Nature Center, the Wisconsin Department of Natural Resources and Wisconsin’s tribal communities aims to reverse the damage. This year marks the project’s 20th anniversary.
Staff collect sturgeon eggs, then hatch and raise them in a trailer at Riveredge Nature Center using water from the Milwaukee River. Over the past 20 years, the program has released more than 23,000 sturgeon.
Each fall, that work culminates in Sturgeon Fest, where people release young lake sturgeon into Lake Michigan at the mouth of the Milwaukee River. Wisconsin Watch attended the festival on Sept. 27 in Milwaukee’s Harbor District. Watch the video for the sights and sounds of the event — and to see us release a sturgeon of our own.
Males mature slightly faster than females and have been spotted in the Milwaukee River. The Wisconsin DNR hopes females will soon reach the age — about 20 years — when they typically begin spawning.
If they do, Milwaukee could see sturgeon spawn in the basin for the first time in more than a century.
