Montana Fishing

Seasons & Hatches


Montana offers the greatest diversity of flyfishing waters anywhere in the world. From floating the big rivers and casting large salmon flies and streamers or matching the hatch on one of the spring creeks--Montana has everything for the visiting angler. My outfitting operation is quite different than most.  I am not tied to one river, flyshop or lodge and am constantly traveling to be on a river when it is fishing its best. I encourage you to consider sampling different streams while you are here.

The trout fishing season begins in late April on the Bighorn River. The river produces incredible hatches of midges and small mayflies until the end of May. This is an excellent time for the fisherman who likes to fish light lines and small flies to rising trout. It is demanding fishing that requires precise presentations, but the trout are very hungry after the long winter. It is also time for the Mother's Day caddis hatch on the Yellowstone River near Livingston. Just before runoff begins, blanket hatches of tan caddis flies cover the surface of the water. If you are coming to fish at this time of year, I would recommend that you plan your trip to combine these two rivers by flying into Billings and leaving from Bozeman.

June is the beginning of salmon fly season when this large stonefly brings a carnival-like atmosphere to rivers like the Bighole and the Madison. If  casting large dry flies and watching the slashing strike as a large trout tries to inhale your fly is what you like, this is your season. June and early July are the best months to catch big trout feeding on top.  The nearby Beaverhead River is also available for  small stream fishing and has prolific hatches of pmd's and small stoneflies home to some of the largest trout you will ever see. It is the supreme challenge of big trout and light tippet fishing. The town of Butte has an airport that is served by most major airlines and is only thirty miles from these two rivers.

The Fourth of July is the true beginning of summer in Montana. There are still some stoneflies around especially on the Yellowstone River which begins to clear at this time. Many of the smaller and lesser-known streams are fishing at their best from July until the end of summer. Casting grasshopper imitations from the boat is at its best in August.  The Missouri River also fishes well in July and August. Caddis, pmd's and trico hatches are abundant on this smooth flowing stretch. The rainbow trout are fast and challenging, and if you ever wondered what all the backing is for, try these fish on 6-x tippet! Accommodations can be difficult to obtain so make your plans early if you are coming during the prime summer months.

Fall is a beautiful time of year when the crowds are down, the fish are in great shape, and most of the streams are low and fishing well. The Bighorn can be exceptional with tremendous hatches of caddis and early morning tricos. The Bighole is also a sure bet in fall.

As you can see, there is not a bad time to fish in Montana and if you are flexible during your trip and willing to travel, the fish will be biting somewhere. My last bit of advice is plan early, fish often.
