how to manually type in discharge-elevation curve as tailwater condition for pond

[galaxy2014]

Hello,

I create a pond in HydroCAD, its principle spillway is weir. I have a discharge-elevation curve for this weir as shown below. Now I want to manually type it into the HydroCAD, so the water will flow out according to the discharge-elevation curve. does anyone know how to do it?

A "special outlet" will let you enter a custom stage-discharge curve. (But you'll find it easier to use one of the built-in weir options.)
