From the benchWith overcast skies and rain in the forecast through Sunday, BWO hatches on the Bighorn will be prolonged and intense — don't rush to switch off dries once fish start rising. Position yourself at the head of a flat, cast upstream, and mend aggressively to get a full 10–15 foot drag-free drift through the feeding lane. If you're nymphing, drop your indicator depth by 6 inches from your summer setting; at 1,680 CFS the current is slightly slower and fish are holding a touch shallower than mid-summer. Monday's clearing skies and 70°F high will shift the bite toward early morning and late afternoon, so plan your float accordingly.
