Maximum HGL Head Class in InfoSWMM AND H2OMAP SWMM

You can find the node flood or surcharge maximum occurrence during a simulation in the Junction Summary Report table in InfoSWMM and H2OMAP SWMM (Figure 1)

Empty                                   if the Node Head is below or equal to the Lowest Link Connecting  Elevation
Below Link Crown            if the Node Head is below or equal to the Highest Link Connecting Crown
Below Maximum Depth   if the Node Head is below or equal to the Node Invert + Full  Depth.  The column Max Surcharge Height above Crown will also tell you how deep the Surcharge in a Node.
Surchaged                           if none of the above is true.
