Tried fishing lower Yapank Lake this AM. Trout were riseing on some form of hatch. It took me about 45 minutes to find the right combination. but I finally caught about a 13 inch brown on a prince nymph fished just below the surface. Loads of people trying to catch stockies on corn and doughballs. What the heck you have to start somewhere. The only thing that ticked me off were the number of dead undersized fish laying on th bottom because the hooks were ripped out of them instead of being cut off.
