12-Mile Creek Dissolved Oxygen Total Maximum Daily Load Report

This Total Maximum Daily Load (TMDL) study was completed for 12 Mile Creek (AUID 07010204-681), which is a tributary reach in the North Fork Crow 8 digit Hydrologic Unit (HUC) located in the Upper Mississippi River Basin in Minnesota. The study addresses one dissolved oxygen (DO) impairment. The 12-Mile Creek DO impaired reach watershed covers approximately 61 square miles in Wright County, Minnesota. The predominant land cover types throughout the watershed are corn/soybeans (46%), hay and pasture (23%) and wetlands and open water areas (14%). The goal of this TMDL is to quantify the oxygen demanding pollutant load reductions needed to meet State water quality standards for DO in the impaired reach.
