Like many anglers we at the Silver Bow could use a few more months of fall. Easy, wadeable water, quiet streams, hungry trout, and reliable hatches.
The big three hatches during the month of October are: October caddis, mahogany dun mayflies, and blue winged olive (bwo) mayflies.
If you find yourself venturing out on any of the local rivers during this time of the year make sure you have a few of these players in your box. The one exception being that if you fish the Spokane River, it does not get a mahogany dun hatch. Just bwo's, October caddis, and midges.
Hatches during this time of the year generally occur during the warmest part of the day, and October caddis lean towards the later part of the afternoon.
As fall progresses you will see the mahogany duns fade off, as well as the October caddis, and while the blue wings remain important for a bit longer, midges start to enter the equation more and more. Ultimately it will be the midges that hatch latest into the season and will be some of the first of the new year to hatch too.
The fall window is short, but an excellent one. Make the time to enjoy some of the last hatches of the season.
