New York State. Department of Environmental Conservation.This is an index to Large scale hydrography surface water areas tiled by HUC-8 sub-basin boundaries. Surface water areas extracted from New York State Large Scale Hydrography. Connectors added as needed to create closed areas. Continuous hydrography areas for mapping and modeling. Base data for creation of high resolution National Hydrography Dataset (NHD).https://cugir.library.cornell.edu/catalog/cugir-collection-large-scale-hydrography-surface-water-areasPublicLarge Scale Hydrography Surface Water AreasDatasetsAusable sub-basin (02010004)Black sub-basin (04150101)Bronx sub-basin (02030102)Buffalo-Eighteenmile sub-basin (04120103)Cattaraugus sub-basin (04120102)Chaumont-Perch sub-basin (04150102)Chautauqua-Conneaut sub-basin (04120101)Chemung sub-basin (02050105)Chenango sub-basin (02050102)Conewango sub-basin (05010002)East Branch Delaware sub-basin (02040102)English-Salmon sub-basin (04150307)French sub-basin (05010004)Grass sub-basin (04150304)Great Chazy-Saranac sub-basin (02010006)Hackensack-Passaic sub-basin (02030103)Housatonic sub-basin (01100005)Hudson-Hoosic sub-basin (02020003)Hudson-Wappinger sub-basin (02020008)Indian sub-basin (04150303)Irondequoit-Ninemile sub-basin (04140101)Lake George sub-basin (02010001)Lower Genesee sub-basin (04130003)Lower Hudson sub-basin (02030101)Middle Delaware-Mongaup-Brodhead sub-basin (02040104)Middle Hudson sub-basin (02020006)Mohawk sub-basin (02020004)Niagara sub-basin (04120104)Northern Long Island sub-basin (02030201)Oak Orchard-Twelvemile sub-basin (04130001)Oneida sub-basin (04140202)Oswegatchie sub-basin (04150302)Oswego sub-basin (04140203)Owego-Wappasening sub-basin (02050103)Raquette sub-basin (04150305)Rondout sub-basin (02020007)Sacandaga sub-basin (02020002)Salmon-Sandy sub-basin (04140102)Sandy Hook-Staten Island sub-basin (02030104)Saugatuck sub-basin (01100006)Schoharie sub-basin (02020005)Seneca sub-basin (04140201)Southern Long Island sub-basin (02030202)St. Regis sub-basin (04150306)Tioga sub-basin (02050104)Upper Alleghe sub-basin (05010001)Upper Delaware sub-basin (02040101)Upper Genesee sub-basin (04130002)Upper Hudson sub-basin (02020001)Upper St. Lawrence sub-basin (04150301)Upper Susquehanna sub-basin (02050101)New York (State)2000Cornell
