Maumee River Mainstem TMDL:
improving the water quality of the Great Lakes

EOR is developing a Total Maximum Daily Load (TMDL) Study for the Maumee River mainstem, for the USEPA Region 5 (Great Lakes) and Ohio EPA. Located in Michigan, Indiana, and Ohio, the Maumee River basin is the largest source of suspended solids and dissolved reactive phosphorus loading to Lake Erie's Western Basin. This TMDL project will facilitate water quality protection and restoration of future impairments in the Maumee watershed and ultimately in Lake Erie itself. To support the TMDL and identification of pollutant load reduction strategies, EOR partnered with Ohio State University to develop a multi-state SWAT model of the Maumee River basin.
