I cannot for the life of me get this warning to disappear from my model. If someone could take a look at the node that is causing an error that would be great. The model contains a double barrel arch CMP pipe as an outlet structure for a pond. The pond outlet structure elevation is set to the same elevation as the crown of the arch pipe, but I am still getting the error message. I have tried raising the outlet structure ground elevation substantially and that did not help either. I am not sure what else to try. None of my other pond outlet structures with culvert outlets had this issue.
