NRCS is in process of creating a hydrologically correct, seamless and consistent national GIS database at a scale of 1:24,000, which has been extensively reviewed. The HUC 12 dataset for Tennessee is now finished and it has been downloaded. Our new shapefiles include, in their entirety, watersheds that we share with other states.
We now have a HUC 12 Shapefile for our use at- S:\Water\HUC12_TN_Sept2008.shp
Those HUC 12 boundaries were then merged together to give us a new HUC 8 shapefile and it is located at- S:\Water\HUC8_from_HUC12_TN_Sept2008.shp
If you have any questions - please feel free to give me a call-Regan Mcgahen
