Thanks for the suggestions.
Ok, have already added some AB3 piles of crushed limestone, which has fines to 1", a few feet out from the bank.
I do lack any cover for small fish around the shoreline. Have cedar trees sunk out in the middle that reach the surface, but not much around the edges, which is where most of my small BG and FHM hang out in my big pond. Will think about it and work on that cover for small fish by next spring.
