as a young 15 year old i tried to catch a large brown trout over two summers with every lure and live bait i could find to no avail. but on a late afternoon ground hog hunt i spied it in very low water, maybe 15-18" and shot it with a .244 remington rifle. not a mark on it, it just rolled over and drifted with the current. it was 24 " long. certain members of my family were not to happy with me, that was in 1958.
