Thanks to everyone for the suggestions. I have been using Boss Dambrk and Hec-2/Hec-Ras for years but new to modeling dams in Hec-Ras. I did get it to run with a reasonable solution!
Again, thanks!

Thanks for all of your help, but I still cannot get this dam to breach. The only way I can get flow is to increase it in the Initial Conditions. A breach on a reservoir this size should give a peak flow of approx. 3000 cfs. I give up!

Cameron, Thank you for the input. This impoundment will have zero inflow and outflow. How can I set the initial conditions to show the impoundment is full.

Thanks Michael, I have never tried the ModPuls Routing options. I will give it a try!

Thanks. I’ve tried all of those (except a pilot channel) and still not getting a stable run.
I’ll give that a try
