Certified Members
NALMS Certified Lake Managers (CLMs) manage lakes, ponds, reservoirs and other bodies of water. CLMs make decisions that affect the quality and use of these water bodies. NALMS Certified Lake Professionals (CLPs), on the other hand, provide vital data used to make decisions that affect the quality and use of a water body. Our certified members are leaders in their fields who have reached the very pinnacle of professional development in lake management; their depth of knowledge is unparalleled.
This listing of our active certified members – both managers and professionals – is sorted alphabetically by state or province.

Megan.PB.Myers@gmail.com
Megan holds a BS in Environmental Studies from SUNY ESC. Part of her college degree included summer residencies in the Adirondacks, located at SUNY ESF’s Wanakena Ranger School, the Cranberry Lake Biological Station, and Adirondack Ecological Center. In addition, she was accepted into a School of Field Studies Program through Boston University for Wildlife Management, where she spent a summer abroad in Africa in Amboseli and Tsavo near the base of Mount Kilimanjaro in Kenya. Here, she primarily conducted fieldwork including elephant population surveys and vegetation inventories.
Beyond Megan’s degrees, she pursued graduate-level courses in physical science at MCLA and UMass Amherst and earned an extensive amount of continuing education units. She received Certificates in Advanced Field Botany, and Wildlife Rescue and Oiled Response. She has completed several trainings in Wetland Delineation under the US Army Corps of Engineers methodology, and in Watershed Management by the US Environmental Protection Agency. She has accomplished Certifications as a Senior Ecologist with the Ecological Society of America, a Professional Wetland Scientist (PWS) with the Society of Wetland Scientists, Apprentice Wetland Scientist with the NH Board of Natural Scientists, and now also a Certified Lake Professional (CLP) with NALMS. She is a member of the NYS Federation of Lakes Association, North American Lakes Management Society and on the Board of Directors for the Soil & Water Conservation Society-Empire NY Chapter.
Megan is an NYS DEC Licensed Volunteer Wildlife Rehabilitator and NYS DEC Licensed Nuisance Wildlife Control Operator with a special condition for the use of Beaver Cable Restraints.
Since 2006, Megan had been professionally employed at an engineering firm, Guntlow & Associates, Inc. in Massachusetts as a Wetland Specialist, consisting of a broad range of specialties. She is a Wetland Delineator which demands the knowledge of vegetation identification and sampling, soils interpretation, and documenting indicators of hydrology. In this profession, she provides regulatory consultation for residential, commercial, municipal, and institutional projects. As a consultant, she specializes in some of the most stringent environmental regulations known in the nation, the MA Wetlands Protection Act, MA Endangered Species Act, and US Clean Waters Act. Megan designs environmental plans to meet environmental regulatory requirements, including but not limited to; notes and specifications for onsite erosion controls and sedimentation prevention plans, wetland mitigation plans, riparian restoration plans, and invasive species removal plans. These plans are proposed to local Conservation Commissions, and state and federal regulatory agencies for approvals and issuances of environmental permits.
Megan has recently reduced her consulting services in Massachusetts and Vermont as a Wetland Specialist, to become a new staff member to the Rensselaer County Soil and Water Conservation District (SWCD) in Troy, NY. She’s looking forward to assisting her local community in this new direction.
Megan is a volunteer for the lake she resides on as a 4-H Leader in Environmental Education, a chair of her lakes Environmental Committee, and participates in the PRISM and NYSFOLA’s Citizens Statewide Lake Assessment Program (CSLAP). Here, she is involved in sharing the tasks of conducting aquatic plant sampling and collecting Babcock Lake water samples during the summer months to aid in the preparation of an annual lake report. Lastly, Megan prepared an extensive Native Aquatic Plant Removal Analysis for Babcock Lake, and it was recently included in their lakes Management Plan.
