Problem Description

Why does the hydraulic grade line at my outfall start at higher elevation than the user defined tailwater I entered? 

Solution

In this situation StormCAD compares the user defined tailwater to the critical depth of the conduit and it uses the higher of the two because it's choose the more conservative of the flow for modeling the peak flow.
