Outflow of Catchment Area less than inflow of pond

[Groundwork Construction]

I am modeling an area that is 100% impervious which is directed to an infiltration bed. The report summary from the catchment area is showing an outflow of 1 cfs and a volume of 1933 cf. The report summary for the infiltration bed shows an inflow of 2.18 cfs and a volume of 4598 cf. There are no other inflows directed to the infiltration bed. If the higher numbers are correct, which I think they are, why isn't the outflow from the catchment area showing correctly?

Thanks

How is the infiltration bed represented in the model? As a pond? And you're routing the subcat to the pond? If so, the pond inflow will be exactly the same as the runoff.

If you have further questions please post your HydroCAD project file.
