I have been lurking on here for a while. Today is my first day.

Mike Otto just completed renovating an old pond on our family ranch in North Texas. Mike made some great spawing shelves around the pond. Before the pond fills, I was going to haul in truck loads of pea gravel for the spawning areas.

Would it be better if I lined these shelves with a liner of some type before I put on the pea gravel? I don't want the gravel to get buried over time in the sediment.

Any recs?
