Problem delineating watershed
I am using ArcGIS 9.3.1 and GeoHMS 4.2.93.22
Any ideas what may be causing this issue?

Well I am not sure what my error was. However, I had all my datasets set to an Albers Equal Area Conic USGS projection. I went ahead and changed my datasets to a different projection (NAD 83 UTM 15N) and tried to regenerate my project. Sure enough, I was able to complete the project and generate the HMS model schematic and associated files.
Thanks.
