Water Testing-Adirondack Lake Assessment Program (ALAP)

ESSLA provides funding and volunteers to perform deep and surface water quality monitoring through CSLAP (Citizens Statewide Lake Assessment Program), a program of DEC and the New York State Federation of Lake Associations

Water samples are analyzed for pH, alkalinity, conductivity, color, nitrate, chlorophyll and total phosphorus concentrations. Acid rain remains a threat to Adirondack lakes and our testing monitors the acidity status of the lake. Phosphorous mostly enters the lake as runoff from human activity on shores. It fertilizes the lake, which can lead to unnatural plant growth for native and non-native invasive aquatic plants, as well as algae blooms. ESSLA also commissions bacteriological testing. To date Schroon Lake and River exhibit very high water quality.
