Just a curiosity question. I am planning on building some spawing beds in my 1/2 acre pond this spring, but because of the bottom being somewhat soft I didn't just want to dump gravel into an area and see it dissappear. I was wondering if those childrens wading pools (the hard plastic variety) cut off about 6" high and filled with Pea Gravel would work? It would seem to me that the "pool" would keep the gravel contained and it wouldn't sink to deep into the softer pond bottom. Any thoughts? how many should I put in? I think they are about 6ft. in diameter.

Its not how well you do something,
Its how well you look doing it!
