If you're worried about the immediate damage to the back of the dam, then I might look at geotextile road fabrics. I've been using it for several years now under limestone rocks on 24' watershed pipes, and a small emergency spillway. Erosion has pretty much stopped.


I did look into that but finding the stuff where I live has been tough...


Amazon has it. I got the Mutual WF200 Tire Scrub Fabric. It was less than $80, and has held up very well.
