During March and April we see the emergence of our first big hatch of the year - the skwala stonefly. After being dormant for the winter months, the trout are on the feed and we see some of our biggest fish of the year caught on dry flies during this time. Western Montana is one of the few places in North America where you can throw size 10 dry flies in March and April to rising trout! This is truly some of the best fishing of the year! We also see great mayfly hatches of grey drakes, march browns, and blue wing olives during this time frame.
Weather: Highs in the 40s and 50s, lows in the 30s and 40s. Waders recommended.
There is no more classic time to fly fish for trout in Montana than in the summertime. In June our rivers explode with Stonefly hatches. The famous Salmonfly is the first to pop in early June, followed by Golden Stones, yellow sallies, and Bitterroot Stones. As we near the end of June, Green Drakes and PMDs round out an all out smoargasboard of insects for our trout. We see the plethora of stonefly and mayfly hatches last into mid-July, and then we start to transition to terrestrial fishing. Great grasshopper and ant fishing happens from mid-July until early- September. During this time period we also experience the one of the best Spruce Moth hatches in the West.
Weather: Highs in the 70s, 80s, and 90s, lows in the 60s and 70s. Waders not recommended.
In September the days start getting significantly shorter and cooler. Mayfly hatches will return to our rivers at this time and provide the angler the opportunty to present dry flies to rising fish. Hecubas, Mahagonies, and Blue Wing Olives all will be on the water. Fall offers some of the best fishing of the year, and also very unpressured rivers, as the summer crowds are gone. It is also the most beautiful time of year to be on the river as the riverbottoms come alive with color.
Weather: Highs in the 50s and 60s, lows in the 40s and 50s. Waders recommended.
