I think the plans are already ruined by giving them information...always better to be an anonymous caller with a hypothetical question. They threatened to fine my uncle many years ago for mowing a path from his yard to the COE lake shore that was a couple inches too wide. The nit pickers would come out with a tape and measure it exactly. Everything I have heard about them is they are completely adversarial. Best to buy a place with an old pond on it and clandestinely clean it out. I wonder if they have been coming after suburbanites for building 2,000 gallon back yard goldfish ponds? There is nothing said about how small it can be, and not be under jurisdiction.
