I love the screen idea but it scares me a little, afraid it would clog up in a big rain event and create other problems, I have about 4 ft of free board with an emergency spillway but I also have over a hundred acres of watershed and we had a record rainfall for a 24 hr period Tuesday, but luckily not near as much in Randolph county where the pond is at.
Like Stringer said, there's a lot of good money spending ideas to be had on this forum,, all free advice too, that's the good part about it!!
