Don't do it, there are micobes and all sorts of stuff in that water you cannot see. I did this once with the stream on my property that feeds our local lake. Boy was it a mistake. My water got cloudy and it took about two weeks to clear it up which included backwashing my DE filter about 10 times in that period.
