Blackfoot River Fishing Report 7/17/26
!! Weigh Station to the confluence is closed until October 31st !!
Boats can still take out at Weigh Station, but are prohibited from putting in.
Message from FWP as of 6-25-26:
The Blackfoot is dropping into lower, clearer summer flows. The Bonner gauge is around 1,280 cfs, down from the last report, with water temperatures warming into the mid-to-upper 60s. The river can still fish well, but the best windows are moving earlier and later. Plan on fishing mornings, shaded banks, and evening dry-fly windows, and be careful with fish handling during hot afternoons.
Access is important right now. From July 15 through October 31, the Blackfoot is closed to floating from Weigh Station Fishing Access Site downstream to the I-90 bridge. Do not put in at Weigh Station and float past it. Treat Weigh Station as the last takeout above the closure, and plan any Blackfoot float accordingly.
Fish are holding along banks, willow lines, buckets, riffle edges, soft pockets, and slower shelves below heavier water. Dry-dropper rigs are still a strong setup. A Golden Stone, Chubby, Water Walker, or terrestrial-style dry with a PMD nymph, caddis pupa, Perdigon, or small jig underneath will cover a lot of productive water.
Golden Stones remain useful, but the daily hatch activity is now centered on PMDs, Green Drakes, Yellow Sallies, caddis, nocturnal stones, and early terrestrials. PMD spinner dry-fly action is worth watching in the morning, especially in soft slicks, foam lines, tailouts, and slower riffle edges. Fish feeding on spinners can be subtle, so slow down and look carefully before charging through good water.
Evening caddis fishing should be one of the better dry-fly opportunities. When the sun starts to drop, fish may slide into shallower banks, riffle edges, and soft seams. Small caddis dries can be very effective after a bright, hot day.
Weather near Bonner is hot, with a heavy thunderstorm chance today and more warm weather this weekend. Fish early, watch water temps, and be ready for changing conditions if storms roll through.
