If you want to help call Steve Moore at 865-436-1250. He is the head fisheries biologist at the Park. He told me it was OK to post his phone #.
If you relocated the trout to another stream in the park or if you moved them down below the cascade there would be an overcrowding or beyond carrying capacity issue, ie. too many trout and not enough food.
Unfortunately, killing those trout is the prudent thing to do to achieve the goal of the Park Service's brook trout re-introduction program.
The big Fish-Out is good because the trout will be consumed and not wasted.
