Thanks guys! I am going to try it again at the same spot. It only does this though after a good rain because it is draining the overflow from that pond where I shoot other photos.

And Bob.... we think alike. I thought the contrast of the black pipe/plant/rocks/ and water made it more interesting to look at. I had to take a few shots to get just the right amount of pipe in the photo because I couldn't look through the viewfinder on the ground while taking the shot.
