I like the way you think liquid. It's not a matter of running out of rock around here...It's running out of backbones - and our rocks are boulder shaped and not to conducive to friendly stacking, sure wish I had some flat stone on the place. I may have to settle for some nicely stacked cinder blocks with an organized pile of rocks over it. Thanks for the ideas.
On another note, my goals for the pond are yet to be fully decided upon as I think I have decided to give the next year to building the forage base (FHMs). I believe my ambition and my pond characteristics lend themselves to a BG pond with the overpopulated LMB OR a HSB and HBG setup (both with RES). I realize those two are quite a bit different, but if I go with the first (LMB, RES, and BG) how much cover for the YOY is too much? Is there a happy medium? All in all it may not make much difference as I will likely add cover and structure until THE rain comes and fills it up (any day now) which may mean the pond has what it will have. I have read that 20% is a good number to shoot for, but I am not convinced that is all that necessary if you are relying mostly on predation (is that a word?)to keep BG overpopulation and stunting at bay. On the other hand, can you have too much or too little structure for the hybrid route?
