Autumn on Boulder Creek is such a great time...maybe the best! The trout are hungry and the water levels are low. Perfect fishing conditions. One suggestion, though...plan your fishing for later in the day. The nights are getting colder (dropping water temps) so the fish may not be very active in the mornings. Between 1pm and about 4:30 is the best time to be on Boulder Creek in the Fall. Trout will be looking up, so bring dries!
