Very good conditions overall here, although you will have issues with weeds and off colored water at times when the cattle wade in the Hot Creek tribs. Very strong caddis activity with some smaller mayflies showing late mornings. There are more small browns around than I have seen in a few years, and a few cutty's still holding in the deeper pools.
Flows are great currently, and I hope they will hold for the summer but would not bank on it. Regular DFW plantings in the campground section downstream from the bridge. I like Assassins and flashback PT's in the #16 & 18 range for nymphing. A few skeeters around so have your bug juice ready on the calm mornings.
