Just as I was expecting and informed, Pale Morning Dun hatch was in full-swing and trout were eagerly rising!!
However, for a little period of time, I experienced typical Firehole Conundrum!! = Rising trout & something hatching, but can't take trout!! Big light-colored caddisn, White Miller (Nectopsyche), came into play. Cross-over period between PMD and White Miller was really hard to figure out.
As PMD ceasing, situation became a bit friendly for me!! Now trout were keying on White Miller Caddis!! I tried several different patterns, but this X Caddis with bleached deer-hair was the most effective!! Other deer-hair pattern tied with regular (natural) color didn't do well.
Another feisty 'Bow!
White Miller hatch seemed ending. Yet trout were still rising though somewhat less than before. With cloudy sky with mix of rain, Blue Winged Olive were hatching, just as I expected!!
I swung by Madison, which was amazingly very fishable at this time of year!. A typical Madison Brown caught by a "Typical" Madison method (guess what!?).
I have just stocked up some X Caddis with bleached deer. Also I noticed a recently acquired material = Snowshoe Rabbit Feet dyed in Cream. I substituted with deer hair. See how it works when I hit Firehole next time.
It was a great day for me. Yellowstone Park waters are in great conditions so consequently Southwest Montana water will be in great conditions through the season!! It's not late yet to plan great fishing trips over here! See you in YNP!!
