Citizens Statewide Lake Assessment Program (CSLAP) Reports
CSLAP reports are created from data collected by sampling volunteers from member lake associations. The data collected from May through October is primarily related to lake eutrophication. Lake reports are not available for all CSLAP lakes. Reports will be added annually. Reports from 1997 through 2010 can be found on the New York State Federation of Lake Associations (NYSFOLA) website. For historical reports (before 1997) please contact the Division of Water.
