Lake Sturgeon Spawning

During mid-April to early May, Lake Sturgeon travel upstream to their spawning grounds giving the public a prime opportunity to see these ancient ones up close. They can be viewed from Sturgeon Park located on the Wolf River at the west end of Richmond Street adjacent to the Mountain Bay Trail and Shawano dam. Parking is available.

Sturgeon spawning is dependent on water temperature and flow. During seasons when water flow is high and water temperatures rise slowly, spawning begins when water temperature reaches 53 degrees Fahrenheit. In contract, during seasons of low water flow and more rapid water temperature rise, spawning does not begin  until water temperatures reach 58-59 degrees.

Thanks to $300 sonar transmitters that look like small black flashlights, the Wisconsin DNR plans to follow the whereabouts of hundreds of Lake Sturgeon. Each time a sturgeon carrying a sonar transmitter passes a receiver, the date and time are recorded by computer chips. The information is downloaded twice a year, giving scientists an incredibly accurate and complete picture of just where fish are hanging out and heading.
