The SGID's U024.StreamsNHDHighRes feature class represents streams, creeks, canals, and other water courses and was derived from the National Hydrology Dataset (NHD) flow lines layer. This layer has just been updated to improve the feature geometry and name attributes for the Jordan sub basin, which is basically Salt Lake County.

Updated shapefiles and file-based geodatabase files for this layer are nowavailable on AGRC’s ftp site at:
