(Lake Winnebago) DNR Sturgeon Biologist Ryan Koenigs says you can expect another long sturgeon spearing season on Lake Winnebago. The season kicks off Saturday. Koenigs says water clarity is not as much of a factor on the Upriver Lakes, but is an important one for success on Lake Winnebago. Without hitting harvest limits, the season on Lake Winnebago could run a full 16 days. DNR officials say 12,411 licenses were sold for the sturgeon spearing season on Lake Winnebago and 479 for the Upriver Lakes.
