I bought a house with a pasture where the fence crosses a creek twice. The previous owner had a couple of horses in the pasture and where the fence crossed the creek he had a single strand of barbed wire that crossed the creek about neck high on his horses. This was all he needed to keep the horses in his pasture, but I would like to get some goats to clean up my pasture and I would like to know if anyone has any suggestions as to how I can put a fence across the creek that would keep livestock in and allow the water to flow unimpeded. The creek does not have a great water flow normally, but when we get a big storm it can fill up pretty quick and we can get some wood debris that might clog a fence that is tight to the ground around where the water flows. Any suggestions?
