Michigan's watersheds for USEPA approved Dissolved Oxygen (D.O.) Total Maximum Daily Loads (TMDLs). The watersheds indicate approximate areas used for determination of the waste load (point sources) and load allocation (nonpoint sources) of each TMDL. Data are compiled by the State of Michigan Department of Environment, Great Lakes, and Energy (EGLE), Water Resources Division. At a minimum, this dataset is updated every two years after the approval of Michigan's Integrated Report (303d List). Features include a hyperlink to the applicable TMDL document, and the year of USEPA approval. Version: November, 2020. |
