I believe that the Smith Dorrien is the single most prolific & successful breeding area of Bulls in Alberta, and that these fish are used for the breeding of Bull stocking in other places in AB. So, I believe that the upper K bulls are realated to the lower K bulls as they were harvested as eggs & raised in a hatchery. This is my understanding & may not be gospel truth, but I seem to recall this being said to me by the biologist up there. Anyhow, I think they'll allow a harvest (planned) soon enough as the recovery rates are showing they're doing well. I think you'd be surprised at the size of some of the Bulls I've seen in the OM in places you'd swear they couldn't survive. I have seen 30" bulls in the OM. I think they get that big when they out-compete something else so there's enough food for them to get that big. Lower K has the ability to support these bulls & some will get that big - we just gotta be extra-good fishermen to find the real big boys! BTW, there's 30+" rainbows in there right now, and the cutts are supposed to get even bigger than the rainbows (according to the biologist).
