Problem 

I have an ICPM model where I expect all the pond elevations to settle by the end of the simulation and have nearly equal elevations, but the results I'm getting are not showing that.

Solution

1)  For all your ponds that are interconnected check to make sure they only have one pond outlet entrance and one outfall set to a boundary condition type of "boundary element" connected to them.

The following is a valid pond routing configuration:

 

The following is NOT a valid configuration:

 

This is also NOT a valid configuration:

 

2)  Check to make sure all your outlet structure elevation are correct and the correct ponds are assigned as the upstream and downstream ponds if you are using the headwater/tailwater type of "Use Pond for Headwater (Tailwater) Range"

3) This information about troubleshooting a mass balance user notification will also help.
