I'll bet that you will have BG spawning where the pea gravel gets placed, if it's in 18"-36" water depth.....
I can definitely place it in that depth. Just trying to see what everyone would do if this were their pond.
Be aware that shallow gravel covered pond bottoms where light penetrates grows wonderful crops of FA.
I ended up digging up my "beach" with a backhoe to make the water drop off quicker because of the FA. That and I found everyone went swimming off the dock instead of the shore anyway. I made a gently sloping area covered in gravel for the little kids to wade into the water. They put on their floaties and jumped off the dock. And the FA went bezerk in the area so no one wanted to wade in there anyway.
But my pond is very fertile. One not so fertile a beach might be ok. In my spawning area which is shallow with gravel, the BG take care of the FA as needed for their nests.
