The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

Two major forks of this grayling stream come together in this pretty pool.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Hi everyone I am from Connecticut and I fish the Farmington River most of my time. It seems to me that some years the hendickson hatch is heavier than others. What would be the greatest determining factors regarding next years hatch of any mayfly? Some dicussion wants to blame it on high water during a current years hatch but I feel it has to be more complex than that like what if we got a cold frost one night before the spinners have a chance to mate and drop? All answers will be appreciated.

Good luck!
Of course the other question is will the hatch be late or early?
Good luck with that one too.
