The guide team had a slower week over all on the McKenzie. It just got too hot after lunch and was 106f for a few afternoons. That is coming down now and I’d hope to see fishing extend past 11 am now that it is. 
We had our best luck last week with jig streamers and olive perdigons with an orange hot spot. Hatches sucked. Maybe this week they will pop again? Stoneflies, Caddis, PMD’s, Pale Evening Duns are what we expect to see when our conditions there go back to normal day time temps. We fish the river every day more or less, and it isn’t terrible, but the heat definitely changed it a bit last week. If you have a guide trip booked, we will probably leave earlier than normal to get the best fishing of the day in the early morning.
