It's a sad day on the Bitterroot River and other mountain fisheries that meander through snowy regions this time of year.
As the Missoulian writes, "this weekend may be the end of the dry fly fishing on the Bitterroot."
The reason being water temperatures are plummeting, "signaling the may fly nymphs to stay put for the winter months."
So what does that mean for fly fishers?
You either have to head down to the lower elevation fisheries where hatches are still coming off, or try going after the subsurface bite with nymphs.
Streamers can still be productive this time of year, just be sure to fish slow and methodical as the trout (like many of us) are a little slower to react this time of year.
