I use a poly tape wire, which I do not care for, but found using it, deer jump over the fence instead of running through wire and dragging it across the pasture. The poly tape is visible while they are running. Now I am not constantly putting the fence back up.
I have had to keep an electric fence and a single wire around the creek where water continues to run. Also there is over 1000 acres up above that drains into the creek when a hard rain comes, and then some spring water as well, that flows very quickly and flows over the creek bed into the pasture. Often it looks like white water coming over the sides. First year I put up a woven wire fence, it totally destroyed it on two sides. The wire was like a net and caught all corn stalks and cotton that was cut down. I was sick. That was 40 years ago.
Now when the water goes up, It seldom messes the fence up.
The poly wire tape fence does drop the voltage. But maintains enough that they don't want to touch it.
