I was wondering what happens to say the hendrickson hatch on the housatonic river when the rains swell the
river and the water is raging along.This might sound
dumb but does the speed of the water affect the hatching of the insects.Thanks for any replies.

I was wondering this myself but in a slightly different way. With all of the high water we've been having I'm wondering how it impacts the insect populations.
Does the fast water knock all the nymphs loose for the fish, etc. to eat? Would that have an impact on the hatches later in the summer?
Any entomologists out there?

I'm no entomologists but from what I've seen during high river flows it that the nymphs have no problem running on top of rocks during a moderately high river flow, but when I walk upstream from them and disturb the current, it knock them off that rock like it was a tidal wave.
What this means to me is that they can handle a slowly changing current, but if it changes real fast they get washed down stream.
I'd love to hear a scientific explanation for this though and if my observations are correct.
