Executive Summary: Watershed Assessment of Detroit River Phosphorus Loads to Lake Erie

May 2019

This is the executive summary for the final report of the Watershed Asessment of Detroit River Phosophorus Loads to Lake Erie.

The research findings summarized in the executive summary 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 analyzed extensive datasets to develop results that can inform efforts to meet new phosphorus targetes 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.
