There are loads of big stoneflies out on the Warm River to Ashton section of the river, but success has been spotty recently. The same goes for the river from Vernon Bridge to Chester backwaters where action was good last weekend. The few fish we caught in both locations two days ago were stuffed full of bugs. The longer it lasts, the current cool wet weather will delay the big bugs from flying big time. But the longer it lasts, the better are chances for action to pick up on ending. By then big bugs could be flying up the river as far as Riverside or even Box Canyon.
