Detention Pond Void

I'm trying to figure out within the pond storage design in Hydraflow Hydrographs extension what exactly it means by the "voids".  If I'm designing a typical detention pond, what void % is typical?

If you fill your pond with large rocks, the voids are what and where the water would be stored.  

 

I used to love PondPack during designs because if my pond failed - I could turn my voids to 125% and my pond would upsize! 

 

Your excavation/pond would normally have a 100% void ratio.
