RE: routing storm through underground chambers in serives

Sounds like a bug, but even if it wasn't .... don't do ponds in series with any Intelisolve software. Every one I've ever seen ignores variable tailwater effects on series ponds, and gives you results that are very wrong, and often dangerous.

For your application, you want to be running ICPR, HydroCAD, XP-SWMM, EPA-SWMM, or something else built to handle variable tailwater effects. You also want to read the documentation closely to be sure it's handling the routing properly, as some of these softwares can be set up multiple ways, with one calculation method accounting for tailwater and others not.

Alternately, you can change your design around so that all the series ponds act as one big pond by connecting them with relatively large pipes, and only putting one control down at the end. Intelisove can probably handle that, as long as you're in a free discharge scenario downstream of your final control.
