I got the following problem by working with your HEC-GeoHMS program. I want to analyze the watershed that drains to the stream gage. So I select in the HEC-GeoHMS toolbar --> Project Setup --> Start New Project. I defined a new project and named an outlet point. Then I wanted to generate a project (--> Project Setup --> Generate Project). Now I get the following error message: Watershed could not be delineated from the outlet point! This problem occurs in ArcGIS software 10.2.2 and 10.4. I have done all steps like in the User’s Manual Chapter 13. Is there any solution for this problem?
