We have a creek that runs across our property near the road. Normally it is a little thing about six inches deep and maybe three feet wide. But when it rains hard it swells. Yesterday it was as big as I have ever seen it. Maybe four feet deep and out of the banks.
My neighbors have fenced their yard to keep in their three dogs. All large dogs that were rescued from abusive owners. One of them can climb the fence and comes to visit occasionally. She would like to come close and be petted, but just can't quite trust me enough to get closer than about five feet away.
Anyway where the fence crosses the creek, debris catches in the fence. Makes a mat that blocks the water, causes water to overflow the bank, and often the fence get bent over.
So I told my neighbor that I would fix the problem. And started to build a section out of rebar that would be hinged at the top and so would swing to let the debris pass under it.
Last night I came up with a simpler approach. I am going to make a section about five feet wide and 30 inches high ( same size I was originally going to have swing ). But instead of covering it with wire fencing, I am going to make it with one bar vertical in the center and three horizontal bars. So the opening will be 7.5 inches high and thirty inches wide. That should let the debris, mostly small sticks and leaves float through. The section of fence will be held by wire at the top and some plastic cable ties at the bottem. The idea being that if there is enough force on this, the ties at the bottom will break and the water can swing the section horizontal. But the section will normally be held securely in place so the dogs can not get out.
So there will be some welding of the rebar. I have not welded a lot of rebar, but so far have never had any problems with the welds breaking.
Will let you know if Mark one mod zero does not work , and there has to be a Mark one mod one.
