The NCRS has a program that will calculate flow and siphon matters . If they have looked at your location they will have the data and can run the calculations. Go look at the Pond-Dam Piping systems web site.

http://www.ponddampiping.com/index.html see on left side of page - 1 conventional and 2 siphon systems

Selected PB threads on the matter - a lot there.
