...Or in even more other words, can we ever create a pond full of 10 lb only LMB with no little ones? Or even "most"?...
Personally, I think it's doable, but every time I think about it, all I come up with is a snapshot. A moment in a pond's life when everything hits perfectly. You'd almost have to start from scratch every 5-10 years, and that's a pretty big gamble.
A buddy of mine's a ranch foreman at a place that has a 35 acre spring fed lake. This pond has given up more 10+ LMB than any other place I personally know of, including the lake record of 16+ pounds. What it doesn't have is a lot of 4-8 pound LMB, so there seems to be a huge gap in generations. I hope it doesn't happen, but I see the potential for a big fall off in the size of those fish once that oldest generation is gone.
WAG, but I think a well manged pond with multiple generations of healthy LMB would probably provide the best opportunity for a 10+. At least I hope it does.
