Steve Heiskary, Research Scientist, MN Pollution Control Agency (MPCA)
The MPCA has developed draft eutrophication (nutrient) criteria for rivers aimed at meeting Minnesota's aquatic life use standards and Clean Water Act interim goals. A "multiple lines of evidence" approach was used to develop the criteria. This presentation will provide an overview of how the criteria were developed and how they will be applied for water quality assessments, and will discuss the effort to create a site specific river nutrient standard for the Mississippi River from St. Paul south, as well as how that compares to the overall proposed statewide river nutrient standard. Specific reference will be made to the Mississippi River and its major tributaries.
The Mississippi River Forum is made possible by the generous support of the Mississippi River Fund and the McKnight Foundation.
