I am trying to model a pond using WinSLAMM. When I enter my data for a sharp-crested weir, a "Stage-Invert Warning" box pops up with the message, "The elevation at the top of the weir is not equal to the highest pond elevation, which is x.xx." However, when I look back at the pond staging data, the highest pond elevation shown is in fact x.xx. I have tried adjusting the numbers by a hundredth and it does not appear to be a rounding issue. Any help or ideas are greatly appreciated!
