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.
