OSHKOSH – The Wisconsin Department of Natural Resources is preparing for the sturgeon spearing season that will open Saturday, Feb. 8, 2025, on the Winnebago System.
With one of the largest lake sturgeon populations in North America, the Winnebago System supports an annual spearing season that runs for a maximum of 16 days (it closes Feb. 23) or until any of the predetermined harvest caps have been met.
This year’s harvest caps are:
| WATERBODY | JUVENILE FEMALES | ADULT FEMALES | MALES |
| Lake Winnebago | 280 | 717 | 1,002 |
| Upriver Lakes | 70 | 80 | 250 |
| Winnebago System Totals | 350 | 797 | 1,252 |
If any harvest cap is met early, a closure notice will be posted to the DNR’s Winnebago System Sturgeon Spearing webpage and sent to subscribers of the DNR’s Sturgeon Spearing Updates email list.

Season Predictions
The sturgeon spearing harvest is usually dictated in part by water clarity and ice conditions on the Upriver Lakes and Lake Winnebago. This year’s assessments indicate poor water clarity, which could lead to a lengthy spearing season on Lake Winnebago. The DNR does not check water clarity on the Upriver Lakes, but due to their shallow water, clarity is usually not a major factor in predicting harvest on these waterbodies.
Spearers will be able to find the season forecast and daily harvest updates on the Winnebago System Sturgeon Spearing webpage and via email.
Registration Information
The DNR reminds spearers that once they have successfully speared a sturgeon, the tag must be validated by tearing off the bottom portion, the sturgeon must then be brought to an official registration station and the spearer needs to be in line by 2 p.m. on the day it was speared.
Any sturgeon harvested from Lake Winnebago must be registered at one of the registration stations on Lake Winnebago, and any sturgeon harvested from the Upriver Lakes (lakes Poygan, Butte des Morts or Winneconne) must be registered at one of the Upriver Lakes registration stations.
Please check the 2025 sturgeon spearing regulations for specifics.
Stay Safe While Spearing
Spearers and spectators are reminded that no ice is 100% safe. The DNR does not monitor ice conditions, so check with local fishing clubs and conservation groups for local ice conditions.
