There was some dry fly action in the evening but early nymphing was the best bet in the sun.  There is some color in the West Branch with the higher release so streamers are working too.  Isonychas, lots of olives, a few caddis, a few cahills, and a few flying ants.  Today should be similar to yesterday with a high of 72 degrees, wind 5 – 10 from the South, and maybe a few more clouds. We’re going to warm up tomorrow with some rain and then drop right back into our normal late summer / early fall weather pattern.  Hopefully the rain and heat bring out good numbers of flying ants tomorrow.
