Nine Lakes TMDL Water Quality Model

Chicago Metropolitan Agency for Planning

Project Description


Lead consultant to assist CMAP in finalizing a Total Maximum Daily Load (TMDL) plan for a 19,000-acre watershed that includes nine regionally significant lakes. Northwater developed a custom model to calculate non-point source pollution loading, identify effective project locations and estimate associated water quality benefits.

The model estimated parcel level pollutant loading of nitrogen, phosphorus, sediment, chloride, and fecal coliform bacteria and provided a platform to develop an implementation plan to achieve the water quality improvement requirements of the TMDL.
