Lake George: Class AA-Special Water
The Department of Environmental Conservation's Water Quality Standards Program sets water quality standards and guidance values for waters throughout New York State. This state program, with federal oversight from the U.S. Environmental Protection Agency, assigns a letter classification to denote the best uses of all the waters in New York State. Letter classes such as A, B, C, and D are assigned to fresh surface waters, and SA, SB, SC, I, and SD to saline surface waters. Best uses include: source of drinking water, swimming, boating, fishing, and shellfishing.
Lake George is classified as a AA-Special waterbody. New York State regulations define AA-Special as follows:
- Class AA-Special waters are best used as a source of water supply for drinking, culinary or food processing purposes; primary and secondary contact recreation; and fishing. The waters shall be suitable for fish, shellfish, and wildlife propagation and survival.
- These waters shall contain no floating solids, settleable solids, oil, sludge deposits, toxic wastes, deleterious substances, colored or other wastes or heated liquids attributable to sewage, industrial wastes or other wastes.
- There shall be no discharge or disposal of sewage, industrial wastes or other wastes into these waters.
- These waters shall contain no phosphorus and nitrogen in amounts that will result in growths of algae, weeds and slimes that will impair the waters for their best usages.
- There shall be no alteration to flow that will impair the waters for their best usages.
- There shall be no increase in turbidity that will cause a substantial visible contrast to natural conditions.
