This channel runs gradually down hill from the back yard by the patio, down the side of the house, and half way down the front side yard. When we get a lot of rain it does it's job marvelously.
Two houses down this is what the manhole cover was doing.
Down stream just a little. We got gas---$99 to fill up---eek!
After we got gas, we went further down stream to take pictures, but my batteries died and I didn't have my extra one with me. Too bad --they would have been good.
