Pond Boss Forums Thread Like Summary - 12” siphon system

I’m in the process of building a pond that will be 5-6 acres with a little over 100 acres of watershed. My original plan was to do a stand alone pipe till I found out about a siphon system drainage. My question is, will a 12” siphon be enough for my lake?

I don't know how your NRCS agents are in your area (some are more helpful than others) but mine came out, figured our runoff area, looked at annual rainfall and maximum rainfall for our area, and gave us a size recomendation for overflow pipe capacity.

So calling your local NRCS office might or might not be helpful.
