Adirondack Lakes Survey Corporation (ALSC) is a not-for-profit corporation established in 1984 as a cooperative agreement between the Empire State Electric Energy Research Corporation (ESEERCO) and the New York State Department of Environmental Conservation (NYSDEC). ALSC's mission is to determine the extent and magnitude of acidification of lakes and ponds in the Adirondack region. ALSC works together with NYSDEC's Division of Air Resources and receives joint funding from the New York State Energy Research and Development Authority (NYSERDA) and the USEPA.

The work began with an extensive baseline survey conducted from 1984 - 1987 that culminated with the 1990 Adirondack Lakes Survey Report. Since that time acid rain monitoring surveys, fisheries and watershed projects have continued (Research). The most intensive of these is the Long-Term Monitoring Project which began in June 1992 and continues presently.
