Narrative Opinion Summary
The Supreme Court of Wisconsin reviewed a dispute involving the Rock-Koshkonong Lake District and the Wisconsin Department of Natural Resources (DNR) regarding water level regulation on Lake Koshkonong. The case centered on the DNR's authority under Wisconsin Statute 31.02(1) to regulate water levels to protect public rights, safety, and property. The Rock-Koshkonong Lake District petitioned to raise water levels, which the DNR denied, leading to a series of appeals. Key legal issues included the deference owed to DNR's conclusions, the application of the public trust doctrine to non-navigable lands, the consideration of wetland water quality standards, and the exclusion of economic impacts in decision-making. The court conducted a de novo review, determining that the DNR overstepped its authority by applying the public trust doctrine to non-navigable areas and improperly excluded economic evidence. The court permitted the inclusion of wetland water quality standards in water level determinations but found the statutory language did not mandate consideration of broader economic impacts. Ultimately, the court reversed the court of appeals' decision and remanded the case for further proceedings, emphasizing the need for comprehensive evidence consideration in water regulation decisions.
