A red user notification is generated that states:

"There was an error during interpolation during interconnected pond routing. Hydrograph Time = XX.XX hours; Time (1)  = XX.XXX hours, Time (2) =  XX.XXX hours." 

Solution

Open the calculation options (Analysis > Calculation Options) and if the output increment is not in a whole number of seconds, change it to a whole number. To change the units to seconds refer to this article .
