Rainbow fishing has been very good from shore throughout the reservoir with the best action occurring from shore on the north end between the Outhouse, Shannon and Kim¿s Marina. Try using leech pattern flies or small black or brown nymphs. Boat anglers are also catching a few rainbows on the north end while fishing close to shore. The Silos area has produced some rainbows as well from both shore and boat. Walleye fishing was slow this past weekend.
