Ann River Watershed Bacteria, Nutrient, and Biota TMDL

This Total Maximum Daily Load (TMDL) study addresses nutrient impairments in Ann Lake and Fish Lake, and fish and macroinvertebrate biotic integrity and E. coli impairments in the Ann River. The Ann River Watershed covers just over 86 square miles, and is located in Kanabec and Mille Lacs Counties in northern Minnesota. This watershed is part of the larger Snake River watershed, which is located in the St. Croix Basin. The goal of this TMDL is to quantify the pollutant reductions needed to meet State water quality standards for nutrients in Ann and Fish Lakes and E. coli and State Index of Biotic Integrity standards in the Ann River. This Ann River Watershed Bacteria, Nutrient, and Biota TMDL is established in accordance with Section 303(d) of the Clean Water Act and provides wasteload allocations (WLAs) and load allocations (LAs) for the Ann River Watershed.
