I have what is called a blue line stream running through my farm. The water in it eventually ends up in the Cumberland River, then into the Ohio, into the Mississippi. , then of course into the Gulf of Mexico. Anyway, because it is considered a blue line stream, I was told that I could not do anything that would impede it's flow. It floods a portion of some of my fields in a period of heavy rain, and I was going to do some work on it to prevent that.

I'd check with the Natural Resources people at your local Farm Service Agency before I did anything to a running stream of water.
