This has been much discussed elsewhere with divided opinion. I am now inclined to believe that it will be selective. Clinger-type and borrougher-type nymphs, stoneflies, and fast-water caddis will have made it through largely unaffected.

Swimmers and clingers will be affected, but some believe those species are likely to surprise.

In my opinion, the little black stones and olives have been back reasonably strong in eastern PA and NJ this spring, despite last fall's flooding.

So I'm optimistic -- although I'm basing this on common sense and not deep experience.
