Watersheds

New York's waters (lakes, rivers and streams) fall within one of 17 major watersheds, or drainage basins. A watershed is an area of land that drains water into a specific body of water. Watersheds include networks of rivers, streams, and lakes and the land area surrounding them. Watersheds are separated by high elevation geographic features (mountains, hills, ridges).
