The river is at optimum summer condition. Running at 2.50 on the USGS gage, temp about 75. There are still penty of stockies to catch and they have had a chance to spread out. So walk the banks and look for rise forms upstream to cast to. The substraight you will encounter in most of the river will be boulder size and smaller. For that reason I usually walk the banks up river and look for fish rising then carefully wade down stream casting at a 45 degree angle down & across, swing wets and streamers.
Now is the time for Stimulators with a dropper, big Zebra Caddis & flying ants. Popping a stimulator on the surface will bring good results.
