Reconditioned NHD+ stream layers for Northwest U.S.

  National Stream Internet hydrography network - GIS stream shapefiles for the United States New - National Stream Internet hydrography network for SSN Analysis - These NHD Plus version 2 stream hydrography layers for the entire continental United States have been editing and reconditioned to work consistently with the SSN package for implementing the spatial statistical stream models. Edits were performed useing the STARS toolkit and consisted of removing unconnected stream segments and reducing braided stream segments to single-threaded streams.
