The nights here are now really starting to cool off. Yesterday I was on the Hot Creek/ Upper O complex at 6:00 am and the temps were 30 degrees. As soon as the sun hit the coat was off and the fishing was off to a strart and going as well.. Not too much in the way of bug activity has changed too much from my last report on this water. I have been seeing less hoppers due to the freezing nights. The water level has remained about the same and is now very clear making the fish very easy to see, and easier for them to see you. The weed slots continue to test the most patient anglers with fish tucked away in any part of the weeds that provide cover. Tiny midges, small beatis and caddis cover most of what you will find. Mid morning I have noted a caddis hatch with mixed attention from the fish on the caddis surface action. Partridge and quill wing caddis in #18-20 cover that hatch nicely. Grey and brown Parachute Adams in the same sizes during a cloudy day are also a fly that could be taken out of the box while on Hot Creek these days. The darker colour WD-40s can be fished as droppers…I would put them off of a larger attractor though..Some fish are still looking up to hoppers. Scan the water before you cast.. Drift the open parts of the weeds. I might of noticed some sort of spawning action going on … I will have to check back on that to confirm though…
