Pond Boss Forums POND CONSTRUCTION Building a dam Permit? Corp of Eng?

I happened to get to visit with an NRCS fellow this past week. He quoted the facts to me that are current here in Ks. I'm recalling from memory, but think I can get close.
An ACOE permit was required if the drainage area was 600 acres or more in western Ks, 320 acres or more in central Ks, or 240 acres or more in eastern Ks. The permit is required if the site involves a wetland or is in a flood plain.
A DWR permit is required for a dam 25 ft tall or more, and/or if the structure will dam up 50 acre ft of water or more (figured to the top of dam, not to the principal spillway).
