Watershed Assessment of Detroit River Phosphorus Loads to Lake Erie

May 2019

The research findings summarized in this report provide a more complete understanding of the relative contributions of different sources of phosphorus within the St. Clair-Detroit River System watershed, including Lake Huron, point sources, combined sewer overflow events,and runoff from both agricultural and urban lands.

This modeling-based project characterized sources of phosphorus and evaluated potential nutrient mangement strategies to help inform efforts to meet phosphorus targets established as part of the Great Lakes Water Quality Agreement. The three-year project was funded by the Fred A. and Barbara M. Erb Family Foundation.
