Hatch of big stoneflies and fish responding is ongoing but won’t last a lot longer. Nymphing remains most effective way to fish in Box Canyon. A few PMD’s are showing in the Last Chance area where caddis and BWOs are attracting fish. On warm days with wind consider pitching a stonefly pattern here once in a while. Wind blows them down from Box Canyon and up from Cardiac Canyon. Longer term resident fish are use to seeing them and will take. Golden stones are showing on the Warm River to Ashton reach and on down stream. The river remains somewhat discolored below Ashton Dam, but fishing has been good for those who present nymph patterns, big and small.
