I'm trying to run the Hydro Network Generation tool on some NHD-Plus streamline data, but am getting the following error:

"Zero-length polylines not allowed [class name = HydroEdge, object id = -1]"

After running the tool the resulting HydroJunction and HydroEdge feature classes are empty.  Has anyone else run into this issue before? Any help would be greatly appreciated.
