St. Louis River Watershed Mercury Total Maximum Daily Load Analysis

The goal of the St. Louis River Watershed Mercury Total Maximum Daily Load (TMDL) is to determine the mercury reductions needed to meet the water quality standards for mercury and support healthy consumption of fish by people and wildlife. Fishing is important in this watershed for economic and cultural reasons, including the exercise of tribal treaty rights; Fond du Lac’s 0.77 ng/L water quality standard protects subsistence fishing. This project will result in the development of the Mercury TMDL calculations and associated mercury source assessment.
