Drue, Glad you got some good opinions. Keep this in mind. I hope you get a good engineer familiar with sport fish ponds. I have seen many ponds overenginerred. They cover their butts not just yours but your paying for it.
One example pond enginereed 3/4 acre outlet was 84 inch. This was on 7 acres of watershed. Dam was huge to handle "200 yr flood". We fired engineer client was out $4,500 hired another guy for $800 and got it approved. He has enjoyed his $3,800 8 inch siphon system for last three yeas with no floods in largest rain you in 100 years here in GA. Saved him $18,000 on dam and outlet pipe. Get my point, do it right but not overkill = over budget.
