Wow. I'd heard that Adair county got the worst of it. I'm in Muskogee county. We got around 8-10" I'd guess.

750 acres is a ton of watershed to deal with. If I were you I'd do some careful planning and consulting with experts before spending money to rebuild it. I second the recommendation for Mike Otto. He came and consulted for us on our new pond a while back. He's great to work with and very knowledgeable.

You might also want to contact your local NRCS agent. They can help with pond and watershed planning and might also know about any government programs to help pay for repairs.

Good luck!
