260cfs– The pmd’s have started to fade as the river and the hatches transition into the fall. Recently there has been a good morning crane fly hatch that can have fish cartwheeling for them as they skate across the river. As usual for this time of year don’t forget your selection of terrestrials like hoppers, ants, beetles. In the afternoon and into the evening be on the look out for baetis and mahogany’s to start coming off.

South Fork of the Boise River
600cfs – The fish have started to get very selective on hoppers after seeing them for so long this summer. The good news is there’s been a strong afternoon hatch of caddis and pinks with a few pmd’s mixed in. If fish aren’t rising nymphing can be an effective way to pick up fish. In the evening look for a caddis hatch to make an appearance right before dark.

160cfs – There is still a smattering of trico’s lingering around in the morning, but with the recent cooler mornings look for the main baetis hatch to start later in the morning with smaller callibaetis mixed in as well. Later in the afternoon fishing big black beetles and hoppers tight to the undercut banks has been very effective. If the wind comes up in the afternoon like it sometimes does fishing a small nymph rig right under the surface can get you into fish.

877cfs- The fishing has been best in the mornings and evenings before and after the boat hatch. In the mornings nymphing and streamer fishing has been the most effective. In the evenings look for pmd’s and caddis to be coming off. If the hatch slows down in the evening streamers can usually pick up some nice fish till dark.
