An issue has been noted when using the Hydraflow Hydrographs Extension in Civil 3D along with the new Windows 10 Spring Update that started rolling out in April of this year:

When computing the total outflow of a culvert/orifice of a pond model, the total outflow numbers continue to increase every time the “Compute” button is selected, instead of resetting to zero for each iteration.

UPDATE.

Autodesk has fixed this issue. Please see the link below:
