Wildman, welcome! How high are we talking about? i.e. from water line (water level) to the top of the retaining wall?
The water level may vary in dry times as much as 2 ft. I was thinking I could put up the wall and back fill about a couple of ft to gain some bank. The levy seems fine. I really am only concerned with two sides...the one next to my house and the far side where I have a building about 12 ft away from the current edge. If I put in the wall and back fill when the level is low I can gain a few feet of bank back and maybe take care of losing any more ground.
The rip rap and rock idea may also work but I wouldn't regain the couple of feet back but I may be able to live wit that.
You guys are a big help. I may get a picture or two on here in a day or two.
