In the Summary Report (of SWMM 5.1.010), the *.rpt file, under the "Node Depth Summary" table there's a column with a heading that reads "Reported Max Depth". Each (depth) value listed under this column is always less than the "Maximum Depth" depicted on the same row of the table, for the corresponding node. What is the meaning of this Reported Max Depth?
It looks like a bug - the reported depth is being multiplied by 0.3048 in SI units.
Thanks a lot Bob, for your attention and the clarification.
