Current Conditions:
The Boulder River near Big Timber and half way to Billings is running clear and cold right now, but it remains a consistent option for fly fishing for the fall season in Montana. It is too low for float fishing and in the low, clear water the wild trout on the Boulder River right now can be quite spooky. Even though the fish on the Boulder River are not pressured, the water is low and clear and the fishing is technical when compared to other rivers in the area. Wading anglers who don't mind a little adventure can find some clear and cold water and some difficult wading. Hatches of Blue Winged Olives will soon be the main offering once the weather finally turns to fall. Because the Boulder River is one of the coldest rivers in our area, it is often the first river to experience fall-like fishing conditions but with our summer-like September water temps are still hanging in there just warm enough to keep any. Streamer anglers can also find some fun fishing on the Boulder right now. The Boulder is low and very clear right now. Fishing is still good but requires a stealthier approach and a decent cast to get to fish before they see you. Nymphing smaller patterns has been productive and there are afternoon risers over the baetis hatch.
If you do fish the Boulder River right now lengthen your leader and drop down a few tippet sizes for the best success. Even though the fish on the Boulder River are not pressured, the water is low and clear and the fishing is technical when compared to other rivers in the area.

The Month Ahead:
For the rest of the year--aside from any major rain events--the Boulder River will remain clear and cold. With the low flows on the Boulder River for the remainder of the season, wading anglers can fish this river and cover plenty of water. The challenge on the Boulder River is the river bottom itself--it is called the Boulder River for reason because the make-up of the river bottom is large boulders and rocks. Fishing the Boulder River requires walking over, across, around, and up-and-over boulders of all sizes. Being in good physical condition and having quality wading gear are all important for success and safety on the Boulder River.
