I have no pictures, but, a lot of old abandoned bog's. During the great flood of 05, any thing that was used too control water flow was washed away. The road that went between two bog's has long been washed away, so think of an hour glass laying down, the sand is replaced with water. This works it's way down stream until it gets too our trail. This section has a pool about 15x30 feet, narrows down too an eight foot wide stream, this is ware our bridge gets us across. So far so good. All the dead wood, grass, and anything else that falls into the bog, works it way down too our pool, then collects side ways, and becomes a dam. We clear it out, but it has gotten too the point, that it is a daily operation. The water in the pool backs up and flows onto our trail, flows along side the dam, and into the stream. I'm looking for an answer too this problem. This work needs too be done on the sly, if you know what I mean.
