I caught one once in Lees Lake, it came from the Allison Trout facility. Put up quite a fight jumped and ran, but I guess for the size of the fish it could have been stronger. But it sure got the attention of the fish whackers there. Especially when I released it.
Sparkplug,
in order for browns to be large enough to become effective predators, they need food. Perch & Prussian Crap decimate the food resources. No grub means very littel growth.
