Project Background

The FOXIL TMDL study area is located in the southwestern part of Wisconsin. The study area includes the Upper, Lower, and Middle Fox River, the Des Plaines River, the Mukwonago River, Sugar and Honey Creeks, the White River, Nippersink Creek, North Mill Creek, and Channel Lake watersheds. The FOXIL TMDL study area covers approximately 1,060 square miles within Wisconsin. A map of the area is located on the Fox Illinois River Basin TMDL webpage.

The Federal Clean Water Act requires that waters not meeting water quality standards be listed as impaired and have a TMDL or equivalent restoration plan developed to address the impaired waters. Many water bodies in the study area are listed as impaired due to excess total phosphorus and sediment. When completed, the TMDL will quantify the different sources of pollution, provide allocations, and prescribe reductions if needed.  In addition to addressing the impaired waters, the TMDL study will also develop protection TMDLs which provide allocations to protect waters that are currently not listed as impaired but could become impaired if pollutant reduction activities are not initiated or maintained.
