I think it could go in different directions. Could be that the two ponds are completely different from one another. A well managed pond could have DD lmb in 5 yrs. And they might continue to grow from the original management. the LMB might be at 10 yrs old and really be big lmb in one or both ponds. On the other hand they could be all out of whack. Like Frank said, could be taken over by plants like bushy Pondweed. Man that stuff is aggressive. HERE U GO "IT DEPENDS" LOL I am betting the two ponds are completely different, even though they were managed the same from the beginning.
