Fwiw the NRCS cost share was going to cost us more out of pocket than just having a pond builder do it.
I divulged from NRCS early. They wanted to put the pond in a low spot and said it would fill slow. I said why not go 100 yds south where a drainage exists. That was like a revalation. The pipe they spec'd was not nearly large enough for projected inflow. They said 6". Pond builder looked where it went under the road and said the county thinks you need a bigger pipe. We ended up with 8 or 10" and Ive still had water almost go around the ends of the dam in the only 2 large events we have had. The NRCS was a total trainwreck.
