TJ, snrub, ozark, rainman, thanks so much for the advice & comments! My pond has very little in the way of rock, one reason I'd like to add some for habitat improvement.

On a slightly different subject, I've got 1/4 acre stock pond close by the main pond where I wish to raise BG and/or TP. 8 feet deep in the middle, but 1 - 3 foot banks for spawning.

Bob Lusk said that this should work well, but that weeds would be a problem in the shallows. I wonder if using an 8 to 12 inch thick bed of clean pebble rock, say 1/2 to 1 inch in diameter, to line the shallow areas would both enhance spawning and keep down weed growth.

thoughts? Has anybody tried this?
