The 2026 Lake Winnebago system sturgeon spearing season kicks off on Valentine’s Day and runs for a maximum of 16 days or until harvest caps are met. This uniquely Wisconsin tradition draws thousands of spearers to ice shanties dotting the big lake, where they peer through holes into the swirling green depths hoping to spot a prehistoric lake sturgeon. The surrounding bars, restaurants, and DNR registration stations buzz with energy as the community celebrates this annual rite of winter. Whether you’re a seasoned spearer or curious spectator, the Winnebago sturgeon season is an experience you don’t want to miss.
