Error in Existing Watershed Delineation
Paige Babushkin
Hi, the following error message continues to come up after I have tried to fix it. I believe it has to do with the outlet file I am providing; however, I have tried delineating without the outlet file as it says optional and the error still comes up. The file I am using has the RES, INLET, and PTSOURCE set to 0, and each outlet has its own ID. Am I missing a value that's needed and does anyone know how to solve this? Thank you!
