Water conditions remain good here, with a small flow increase recently. The spring run of cutthroat is over. Fish will be planted around the campground for the summer. The section downstream from the Benton Bridge all the way to Crowley Lake is now open. Special regs remain in place above the bridge. As summer rolls on look for the smaller resident fish, and those that will get planted to provide action along the UO. Small dark spring caddis, & micro midges are triggering feeding activity from the resident trout on the warmer days. Attractor patterns will get you looks from what is left of the bigs. SJ worms, crystal Vanderleeches, crystal soft eggs, Assassins, and Agent Orange patterns have got us into them while nymphing below an Under-cator. Size 16/18 adult Blue Winged Olive patterns, & small parachute midges will replicate the hatches. Flashback pheasant tails, & Assassins are spot on replicas for the nymph stage of this cold water mayfly. Use #18-22 gillies, crystal chironomid pupa, broken back midges, crystal tiger, & zebra midges for nymphs that imitate midge larva or emergers. Caddis larva are present on the stream bed pumice rocks now. Olive crystal caddis imitations can be a good call for the resident fish grubbing the bottom during warmer periods. Parachute adult midges will get you looks when the fish are feeding on the “clusters” late afternoons. I have seen a good number of trout fry along the banks, and in the slack water. Small Punk Perch, & crystal leeches fished below an Under-Cator can get some nice bows to hit these “strymph” patterns as they hunt for the tiny meals.
