US USEPA N A Nutr trien ient S Strategy E Elem emen ents ts 1. Prioritize watersheds for nitrogen and phosphorus loading reductions 2. Set watershed load reduction goals based upon best available information 3. Ensure effectiveness of point source permits in priority sub-watersheds 4. Agricultural Areas 5. Stormwater (non-MS4) and Septic Systems 6. Accountability and verification measures 7. Annual reporting of implementation and biennial reporting of load reductions 8. Develop work plan and schedule for numeric nutrient criteria development

Summa mary • Statewide average riverine waterflow, nitrate-N load and TP load estimates 2013–2017 were 13%, 7%, and 26% greater than the 1980–96 baseline period. • Point source 2017 estimated point TP and TN discharges were 22% and 14% lower than 2011 estimates. • At the HUC 8 scale, nitrate-N and TP yields 2012–17 were generally similar to 1997-2011 values, with some exceptions: • TP load reductions in Chicago and Des Plaines • TP increases in the Upper Sangamon and elsewhere • Changes in nitrate-N load were correlated with changes in water flow for HUCs with high N yields • Nitrate-N reductions per unit of water yield in the Mackinaw, Spoon and Kaskaskia Rivers and Henderson Creek
