Kalamazoo River Watershed Management Plan Prepared by the Kalamazoo River Watershed Council March 2011 This Nonpoint Source Pollution Control project has been funded in part through the Michigan Nonpoint Source Program by the United States Environmental Protection Agency under assistance agreement #2006-0148 to the Kalamazoo River Watershed Council for the Kalamazoo River Watershed Management Plan.

Recommended Citation: Kalamazoo River Watershed Council. 2011. Kalamazoo River Watershed Management Plan. Prepared for the Michigan Nonpoint Source Program (Michigan Department of Environmental Quality and the United States Environmental Protection Agency). ii Acknowledgments This Watershed Management Plan is the culmination of several years of work on the part of the Kalamazoo River Watershed Council and particularly our Coordinator and the lead author of this report, Jeffrey A. Spoelstra. Jeff attended innumerable meetings in the community, studied dozens of reports, and assimilated and compiled the information presented here. The Plan was greatly enhanced by the technical and scientific support of Kieser & Associates, LLC, who contributed with spatial data analysis, map production, and modeling. We would also like to acknowledge our many partners in the quest to improve watershed protection and management in the Kalamazoo River watershed. Funding to prepare this Plan was provided primarily through a U.S. Environmental Protection Agency Section 319 grant administered by the Michigan Department of Environmental Quality (MDEQ; also known as MDNRE during the report preparation). Janelle Hohm and Julia Kirkwood of the MDEQ were especially helpful in providing guidance and support. Our work on non-point source pollution has been conducted in close collaboration with the Kalamazoo River/Lake Allegan Total Maximum Daily Load implementation committee, and we received input from many other governmental and non-governmental entities.
