My pond is 1 year old and we repaired the spillway this summer because of 17" rain in 9 days back last winter. The spillway had a decent growth of rye grass. This week Gustov hit us hard and the bottom approx. 120+ feet washed away again. This time I had a thick crop of bermuda grass 6" tall, fertilized last spring w/ 10-20-20 & 13-13-13. This summer I also used miracle grow, so you know it was thick with deep roots, but it still washed away. I have 120+ feet of pond liner down now to stop it from washing out any higher up the spillway.

I was thinking maybe next summer when things dry out, to put large chunks of that gray rock where it is washing out up to the top of the spillway. I know I will not be able to mow it, but I could weedeat it. What do you guys suggest?
