the first 40 feet or so of my pond is very narrow-maybe 6'wide. early this spring i dug that area to about 3 ft deep and put a rip rap rock dam across there. the rock is about bowling ball size or maybe a little smaller. it is all limestone. i did it to help slow the water that flies into my pond during a heavy rain.

does some of the rock erode away with water flow and help lime the pond? looks like it would get cover with dirt and algae kinda quick and not much of the stone will be exposed.
