Hello Scott and all,
Thank you so much for contentious help and support for PondPack related issues.
I have final results for one particular pond and its outlet design.Now, I have to confirm whether I can accept the final design based on final routing results table or also I have to consider outlet design table .Because my Estimated free board depth column and estimated peak outflow vs target column are failed in outlet design table but both columns are passed in routing table.
Please find the following snapshots and uploaded model for review.
If this design is Ok then I will move forward for other design.
Thank you once agaiin.

Hello Hari,
Thank you for sharing your model.
All the scenarios are failing for "Estimated Peak Outflow vs. Target" till Step 4 (Outlet Design). You can try different composite outlet structures and try to have your target rating curves as close as possible to your composite outlet rating curves. You can model different composite structures or tweak with the parameters set for your existing structures.
However, in Step 5 (Routing) the structures are "Passing". In the "Routing" step PondMaker actually routes the hydrographs through the network as compared to Steps 1 to 4 which are estimates.
Another recommendation is to try with the "Curvilinear" storage estimate method as against the "Upper Boundary" method (which gives a conservative estimate). You can see if the results are acceptable.
Here are some informational articles which can help you further;

What do all the lines in PondMaker step 4 represent?
Here is an informational video for using PondMaker;
Hope this helps.

Hello sir,
Thank you so much for helping me out time and again. I noticed that the pass and fail column only depends on your tolerance setting.Here I ignored that because my proposed peak flow and volume are below than my target which is my goal.
But, still want to make sure step 4 (design step) is crucial or 5 (routing step) because in my all design routing step (step 5) are passed and the peak flow and volume are below than target in that particular step whereas somewhere they are fail in step 4.
Please find the following attachment to help me out.
As this is my initial phase in this program, please suggest if I am assigning any wrong input or following wrong steps.

Thank you,
The routing step is what matters - that is when you commit your design to the model and perform an actual hydraulic simulation using that pond and outlet. As Yashodhan mentioned, the design step (and everything before it) is based on estimates and is intended to get you close to something that may work well in the real system, and then in the routing step you prove if the design works or not.
If you are getting good results in the routing step, export the designed pond and outlet in the model (final step) and analyze it using the normal compute button and various visualization options like graphs of pond inflow/outflow/elevation.
