My father-in-law was visiting from Illinois. I wanted to take him to Banks Lake since it fished so well in late July, but had to settle for Porcupine Bay since our only opportunity to fish was a windy day. The wind gusts to 25 mph didn't bother us on the Spokane Arm above Porcupine. We enjoyed very good success catching rainbow trout and modest success catching walleye. We caught at least 25 trout (14 to 18 inches) along with 15 walleye (11 to 16 inches).
