River Conditions: About 1900 cfs @ Umtanum, clear and getting slightly colored throughout the day, Water Temp was 58° Check here for current water flows and predictions.
Hot Flies: YB Hares Ear (#14-18), Chubby Chernobyl (#8-12)
Bug Scene: Salmonflies higher in the system, March Browns and Caddis still prevalent
The salmonflies are making a show as you work your way higher in the Yakima River system. The March Browns start hatching midday and last for a few hours before dying when the shadows get long. The caddis start hatching around the same time as the March Browns and ramp up into the evening and after dark. The caddisflies we are seeing right now are fairly large (#12-14) and have a dark colored or brown body.
Fishing Forecast: Dry droppers and waiting for the evening caddis hatch
Fish are looking up to large attractor patterns like Chubby Chernobyls (#8-12) in purple, royal and orange in the Upper River. Dropping a nymph like a YB Hares Ear (#14-18) off the back of a larger dry fly and fishing a dry-dropper system can produce as well. PT Cripples (#12-18) imitate an emerging or crippled March Brown and an Adam’s Parachute (#12-16) in brown imitates the adult. A Purple Haze (#12-16) is a great all-purpose mayfly imitation to fish when there’s a hatch going on. When the caddisflies come out, an Elk Hair Caddis (#12-16) or Fluttering Caddis (#12-16) can work to imitate the adult, while CDC Emergers (#14-16) and La Fontaine’s Sparkle Pupa (#12-16) can imitate an emerging or crippled caddis.
Look to fish your dry flies close to structure and in calm edges along the bank. Fish will hold in front of submerged rocks and pick off flies as they float by. Also watch for foam lines and back eddies. Watch ahead of the boat and set up for risers as you come across them!
If you’re nymphing, try fishing a Pat’s Stonefly (#8-12) in coffee or black to imitate the Summer Stoneflies and Salmonflies. Gold Lightning Bugs (#14-18), Waltz Worms (#12-18) in green and YB Hare’s Ears (#14-18) are also great small bugs to throw under an indicator.
Look for deep water and structure like boulders or drop-offs to put your nymphs. Slow-moving currents that butt up against the main current will be great holding areas for trout.
