Not a whole lot has changed here on the Yakima, other than a brief cool down over the last few days. The fishing has still been great, especially early and late in the day with big stonefly imitations. Chubbies, Glomers, PMX, Stimis have all been productive patterns to have in your box in #8-12. Fishing midday has been hit and miss, with certain sections fishing well with hoppers, including Morrish Hoppers, Dave's Hopper and Clodhoppers in #10-12, and other sections fishing better with a dry/dropper rig. consisting of a Chubby or Hoppercator trailed by a smaller Pat's Stone or tungsten bead Hare's Ear or PT. When fishing hoppers midday, remember that the fish are looking for these insects extremely tight to the banks, so good casting and mending skills will really pay big dividends.
It looks like we are going to see another stretch of hot weather by midweek, so fishing early and late will continue to be a good option. We are still recommending staying away from the lower river for your afternoon/evening fishing until water temps cool down; the upper river is fishing well in the evening hours and has colder water this time of year.
