There are 17 major watersheds, or drainage basins, across New York State, with Onteora located in the Delaware River Watershed. Upstream from Wildcat Falls, as you’ll soon see, is the swamp and the brook, that flow to Wildcat Falls. That water makes its way to Orchard Lake, and then into the Sprague Brook, eventually making its way to the Delaware River, the Delaware Bay, and finally, the Atlantic Ocean.
