New York Aquatic Gap Analysis GroupThis shapefile contains polygons representing the stream basins of the Allegheny River watershed in western New York. Basins were developed for stream segments at the 1:24,000 scale from 7.5 minute topographic quadrangles. For the purposes of this study, a stream segment is defined as the portion of stream from tributary confluence to tributary confluence. To define the drainage basin for each stream segment.Shapefilehttps://cugir.library.cornell.edu/catalog/cugir-007897PublicStream Basins, Allegheny River NY, 2007DatasetsAlleghe RiverNew York (State)1996Cornell
