You mean you want to install a moat around your place? Do you think that's a good idea? I'm w/ itsreally on this one, unless there is absolutely no way for the water in the ditch to get back to the house, which it does not sound like from what you said. (ie, I see the water getting from the ditch to the house). I use french drains for gutters, but they are 3' from the house, and their own, separate ditch.
