Flows from Island Park Reservoir are now holding steady around 780 CFS, with water clarity improving as sediment has settled out. Fishing in Box Canyon has been solid with nymphs in the morning and streamer action in the evenings. Dead-drifted olive sculpins and smaller articulated streamers are moving some good fish. On your nymph rigs, go with #16 red zebra midges, #18 Two Bit Hookers, or #16 Duracell jigs. In the Ranch, terrestrial season continues—honey ants, beetles, and hoppers are all finding selective trout when the wind is calm. Mornings and evenings are your best window, so be ready to match timing and presentation closely.
