Maine Lakes Report 2012 Dear Friends of Maine Lakes, This report on the health of Maine lakes reflects the effort of more than 1,000 volunteer citizen scientists who monitored several hundred lake basins throughout the State in 2012. Many of them have been doing so continuously for decades, and a few have been involved for most of the 42 years since the Maine Legislature officially authorized volunteer lake monitoring. Their work is a strong testimony to the level of public commitment in Maine to our clear, clean lakes, and it is probably not coincidental that our lakes have remained as healthy as they have under the watch of these individuals. The Maine Volunteer Lake Monitoring Program (VLMP) is believed to be the longest-standing statewide citizen lake monitoring program in America, having been formed at about the time of the passage of the historic Federal Clean Water Act. The Mission of the Maine Volunteer Lake Monitoring Program is to help protect Maine lakes through widespread citizen participation in the gathering and dissemination of credible scientific information pertaining to lake health. The VLMP trains, certifies and provides technical support to hundreds of volunteers who monitor a wide range of indicators of water quality, assess watershed health and function, and screen lakes for invasive aquatic plants and animals. In addition to being the primary source of lake data in the State of Maine, VLMP volunteers benefit their local lakes by playing key stewardship and leadership roles in their communities. Our primary partners are the Maine Department of Environmental Protection (DEP) and the US Environmental Protection Agency, which provide a wide range of financial, technical and management support to the program. In turn, the VLMP provides these agencies with essential information that they use to manage and protect Maine’s lakes. The relatively small investment of public funding that supports the work of the VLMP is multiplied in value several times through the invaluable, high quality work of VLMP volunteers, and from increasing private support from individuals, organizations and businesses who recognize the tremendous benefits to Maine lakes. Studies conducted throughout the country have consistently shown that lake data gathered by properly trained volunteers are equivalent to, and indistinguishable from that of professional lake scientists, at a fraction of the cost! The additional invaluable benefit of public education and stewardship that VLMP volunteers provide to communities throughout the state is one of Maine’s best examples of grassroots natural resource protection. The effectiveness and strength of the VLMP is in part due to collaborative partnerships with other entities, including agencies and organizations throughout Maine and the U.S. This collaboration has formed a powerful resource for technical expertise, outreach, and access to a great deal of information concerning Maine lakes and their watersheds. Since the earliest days of the program, the VLMP has been at the forefront of gathering lake data in Maine and the U.S. For more than four decades, the total number of active individuals involved in monitoring water quality, and in screening public waters for invasive aquatic species has increased steadily. This document is a testament to their remarkable commitment! e Volun n te i e a r M Scott Williams L a m k VLMP Executive Director a e r M g o o n r i P toring Maine Lakes Report 2012 Acknowledgements Written by: Layout: Contributors & Reviewers: Scott Williams Jonnie Maloney Linda Bacon Roberta Hill Roberta Hill Database/Computer Technical Scott Williams GIS/Mapping: Assistance: Jonnie Maloney Linda Bacon Linda Bacon Christine Guerette John McPhedran Christine Guerette Doug Suitor Jonnie Maloney VLMP Staff VLMP Advisory Board Scott Williams, Executive Director Holly Ewing Roberta Hill, Invasive Species Program Director C.
