The Roeliff Jansen Kill watershed is a major tributary of the Hudson River, which empties to the Hudson at Linlithgo. Most of the watershed lies outside of Dutchess County in Columbia County, although parts of the northern Dutchess Towns of Northeast, Stanford, Pine Plains, Milan, and Red Hook, are within the Roeliff Jansen Kill watershed. Major streams in the watershed include the Roeliff Jansen Kill and Shekomeko Creek.

Natural Features and Habitats

According to the US Fish and Wildlife Service (FWS), the Roeliff Jansen Kill is a large cool-water tributary with a medium stream gradient located six miles south of the city of Hudson at river kilometer 175 (river mile 109). The riverine habitat includes six miles of accessible area, extending from the mouth to a natural barrier at Bingham Mills, which is available to migratory and resident fishes. In 1992, based on macroinvertebrate sampling, the water quality in the Roeliff Jansen Kill was found to be good (non-impacted), but this may have changed since that time. The area provides important spawning habitat for alewife, blueback herring, white perch, and resident smallmouth bass and the introduced brown trout (Salmo trutta). At the mouth of the Roeliff Jansen Kill, there are shallow waters that provide important spawning sites for American shad. Small areas of marsh and mudflats at the mouth support at least one rare plant species, the kidneyleaf mud-plantain. (For more information, see: http://usasearch.gov/search?query=roeliff&v%3Aproject=firstgov&affiliate=fws.gov).

Parts of the Roeliff Jansen Kill are also considered to be part of the Harlem Valley calcareous wetlands complex, which encompasses the valleys and adjacent ridges in the Taconic Highlands of easternmost Putnam, Dutchess, and Columbia Counties in New York. According to the US Fish and Wildlife Service, the northern portion of the Panhandle wetlands and the Drowned Lands area drain into the Roeliff Jansen Kill. The area encompasses the calcareous wetlands, uplands, and ridge-top habitat which support rare reptiles, waterfowl, and raptors, as well as rare plant habitats and communities. Most of the wetlands and uplands in this habitat complex are in private ownership (For more information, see: http://library.fws.gov/pubs5/web_link/text/hvc_form.htm).

Top Threats

Top threats to the Roeliff Jansen Kill include non-point source runoff from agricultural operations in the watershed (including chemical and biological), and increasing population density and development, which is exacerbating problems of flooding, erosion, deposition, water quality impairment, and ecosystem degradation.
