Public meeting to be held on proposed Butternut Lake musky regulation change

The proposed change stems from Citizen Resolution 020120 presented at the Spring 2020 Fish And Wildlife Hearings hosted by the DNR and Wisconsin Conservation Congress. The changes would apply Wisconsin’s standard muskellunge harvest regulation of a daily bag limit of one and size limit of 40 inches or longer.

The musky population in Butternut Lake was reduced from high to moderate abundance, and musky growth rates and size structures have rebounded. Surveys in 2018 and 2019 confirmed that Butternut Lake’s muskellunge population now has the desired density (0.2-0.3 adults/acre) and size distribution (25-50% ≥ 38"), meeting the goals defined in the 2005 Butternut Lake Fishery Management Plan.

As a result, there is no longer reason to promote selective harvest of medium-size fish, making the 28-inch minimum size limit unnecessary.

Because it seeks to replace a special regulation with a standard regulation, the proposal can be routed through the streamlined procedures in Chapter NR 20.35 of Wisconsin’s Administrative Code. If enacted, signs will be posted at Butternut Lake’s pubic access sites before the change would take effect on April 1, 2021.
