We usually go to the little red a few times a year when it gets real hot and trout magnets work great. But our go-to, and I dont know if its a "faux pas" of trout fishing but we have always used crickets. If they will eat a fly on top of the water, why wouldn't they eat a live creature that looks similar to a fly/nymph/etc? We usually get funny looks from folks, and the fly fisherman really get to staring us down, but we rig them up with a modified C&C rig with a fixed weight to cast and catch on the rocks. Good luck!
He said, "Throw your net on the right side of the boat and you will find some." When they did, they were unable to haul the net in because of the large number of fish.
