I had read about doing this in several different sources, and just decided to give it a try where there were few fish working sporadically, probably taking little olives that were hatching. The fish took the Iso flies confidently, at times where there was no previous surface activity in a spot. It's something I'll certainly try again anytime that Isos are active. Does anyone else have an experience like this one?

It would seem that in general at this time of year streams may be low and clear. Also, fish are well-educated. Riffles mask both the angler, her or his line, and errors in drift. Blind casting in thin or flat water may be less productive because of the above reasons. It is also hard to know where fish are in a big pool. I did hook up with a fish in flat shallow water at the head of a pool, but I had watched him eating Isos before casting to him. Reading the water well may help some in pools, but riffles offer many kinds of lies, and when food is available fish may gather in a riffle to feed. Also, to increase your odds, it may be a good idea to try to spot a few Isos in an eddy or elsewhere to be sure they are available to the fish.

I have far better luck with them in slower tailouts if I move the bug with very short jerky strips, but I can dead drift them in the riffles w/ equal success. From what I have seen they are a very active bug and should be fished as one. Jeff

Moderator Palmyra PA Posts: 1722	Hi Jeff, Are we still talking about duns and emergers or are we moving on to nymphs? I've been moving my Iso nymphs a good bit, as per John S.'s guidance, but typically aim at dead drifts for duns and emergers which I fished mostly during most recent outings. However I did have one fish hit an emerger as it started to swing in the tail of a pool. And I'm sure wet flies swinging or stripped also could elicit some interest when Isos are darting around trying to emerge.

Moderator Palmyra PA Posts: 1722	No problem, Jeff. It got me thinking about the other aspects of Iso fishing as well and about fishing wet flies, which I've had good luck with too during Iso emergences. What works best certainly varies from day to day and from angler to angler.
