Indiana Volunteer Lake Monitoring Report: 2009-2011 Prepared by: Sarah R. Powers and William W. Jones School of Public and Environmental Affairs Indiana University Bloomington, IN January 2012 Prepared for: Indiana Department of Environmental Management Office of Water Quality Indianapolis, IN January 2012 ii ACKNOWLEDGEMENTS The chemical analysis of water samples is a labor-intensive process. The total phosphorus and chlorophyll a results in this report would not have been possible were it not for the capable help and skills of many SPEA graduate research assistants who conducted the analyses. Julia Bond provided GIS graphics assistance as well as much needed support with training this past year. Julia has also put in countless hours updating the volunteer portion of our website to make it much more user friendly. Funds for this program were provided by Section 319 Lake Water Quality Assessment Grants from the U.S. Environmental Protection Agency. Laura Bieberich of the Indiana Department of Environmental Management was the Project Officers. Most importantly, THANK YOU to all our volunteer lake monitors! Your hard work and dedication contribute greatly to the understanding and sound management of Indiana’s lakes. 2009-2011 Volunteers by County BROWN COUNTY Jack Carr Bonar Lake Quinn Hetherington Cordry Lake Troy Turley Center Lake David Jarrett Sweetwater Lake John Bender Diamond Lake Buzz Settles Sweetwater Lake Sandra Buhrt Elizabeth Lake Chuck Brinkman Irish Lake ELKHART COUNTY Jeff & Pam Thornburgh James, Oswego, & Gordon Mills Heaton Tippecanoe Lake Larry Lehman Indiana Debra Hutnick Palestine Lake Sandra Buhrt Rachel Lake FRANKLIN COUNTY Toney Owsley Ridinger Lake Tag Nobbe Brookville Kathy Hiatt Sawmill Lake Reservoir Ron Hill Sechrist Lake Dean Schwalm Syracuse Lake FULTON COUNTY Mike West Waubee Lake Dennis Grossnickle Lake Manitou Daniel Berkey Lake Wawasee Jerry Caylor Nyona Lake Don & Dawn Meyer Webster Lake Chris Cummins Winona Lake HARRISON COUNTY Chris Rankin Winona Lake Guy Silva Pinestone Lake Dave Patterson Yellow Creek Lake JOHNSON COUNTY LAGRANGE COUNTY Tom Houghman Lamb Lake Joe Kraft Adams Lake Howard Pratt Big Long Lake KOSCIUSKO COUNTY Tom Henry Big Turkey Lake Kathy Hiatt Banning & Little Tom Mackin Lake of the Woods Barbee Lake Randy Furniss Little Turkey Lake Donald Hagan Big Barbee & Kuhn Lynn Bowen Martin, Olin, & Lake Oliver Lake Len Draving Big & Little Terry Gust Martin, Olin, & Chapman Lake Oliver Lake iii Donna Moran Martin, Olin, & Jean Cook Little Long Lake Oliver Lake Nancy Lough Skinner Lake Vanessa Eash Pretty Lake John Fitzpatric Skinner Lake Robert Christen Witmer Lake Colin Tipton Upper Long Lake LAKE COUNTY PORTER COUNTY Brongiel Frank Cedar Lake Paul Borkowski Big Bass Lake Paul Borkowski Holiday Lake Ed Spanopoulos Big Bass Lake Ed Spanopoulos Holiday Lake Robert Minarich Flint, Long, & Loomis Lake LAPORTE COUNTY Christian Anderson Louise Lake Paul and Joy Kamradt Clear Lake PUTNAM COUNTY MARION COUNTY Brian Waldman Heritage Lake Joan Baltz Spirit Lake ST.
