My pond was dug by a contractor while I was away at work. He enlarged it and dug a bit too far into the side hill. I now have an errosion issue to deal with but because of where it is I can't slope the sides so I need some kind of retaining wall that the fish won't hurt themselves on come spawning time. Right now I have liners temporarily held down by rocks. Don't want to do a stone wall for fear of injuries but what else can I do? Wood will rot, concrete with leach and be rough, same with pavers etc. He did dig me an 18 inch shelf along the side of the pond wall so I can build something there without it sliding to the bottom of the pond. Need advice soon before winter comes and takes the yard away.
Thanks,
Jeanne
