RE: pond outflow
If you want to do it right, you'll need to know at a minimum:
Size of the watershed to the pond
Slopes / land cover of the watershed
Location of the property (to determine rainfall at your design storm)
Size of the pond
Then you design your outlet works so they won't erode at your design storm. This is a fairly easy (cheap) task for a hydrologist if you don't have to pull a permit. The difficulties (expense) arise when you have to get some sort of regulatory approval.

RE: pond outflow
Plan on calculating the 100-year stormflow rate for the basin, proving flow capacity using the Manning's Equation for channels, and providing 1/2 to one foot of freeboard to satisfy any regulatory approval.
RE: pond outflow
Is routine maintenance of farm ponds exempt from regulatory approval? I know our friends in Ag sneak past a lot of the headaches have to deal with in land development.
