The change is happening
Soak up the last of the summer-like October weather. The shift this weekend to more traditional fall weather will definitely bump the fishing into "fall mode" on pretty much every river around the region.
Mike and I snuck out for some casts on the Spokane River yesterday and by mid day the waders were too much to wear so it was a wet wading session from there out.
Because of the unusually warm weather the trout were still in classic summer water, though some trout were starting to hang in the slower / deeper currents that we will be heavily focused on for the next number of months.
Other than some caddis hatching we did get some interest in October caddis adults, which have been seen on this particular river already, but have been more important on rivers like the St. Joe and NF Coeur d'Alene River lately.
The cooler, mild climate over the next few weeks should make for good mid-day afternoon fishing on most rivers, but definitely be prepared to nymph or streamer fish in the mornings. No need to be out at first light either when night time temps will be in the 30's in the mountains. The trout will be sleeping in a little and so should you!
Get out there and enjoy this fantastic time of the year... this is the time of the year when the big fish come back out from hiding!
