Fly Fishing Season

Because of the wide variety of fishable water, the ranch can produce memorable fishing from late May to mid October, virtually without interruption. There's really no such thing as "prime time" at Three Rivers since, from the day we open until the day we close, we have fishing on one or more rivers that is at its peak.

Early Season - (Memorial Day Through June)

The season here at Three Rivers opens the last week in May when the Henry's Fork is typically in the midst of the Salmonfly hatch. Some very large fish can be tempted to the surface with imitations of this huge stonefly. As water temperatures moderate mayfly and caddis hatches begin in earnest, including Pale Morning Duns and the well known Green Drake hatch. The famous Railroad Ranch opens on the 15th of June and you can experience some of the finest dry fly fishing the Henry's Fork has to offer at this time. The Firehole River also has excellent hatches during this period. By the end of June runoff is receding and some of the smaller rivers are starting to turn on.

Mid Season- (July/August)

July is usually highlighted by the Salmonfly hatch on the South Fork of the Snake, which typically begins around July 4th, followed by other stoneflies and heavy mayfly hatches. There's excellent fishing to be had with large dries as well as match the hatch fishing during the Mayfly hatches. Smaller rivers like the Teton, Fall River, and Warm River come on and fish well throughout the summer, offering a great diversity of fishing opportunities for both wading and floating. July 15th marks the opener for the Yellowstone River, in Yellowstone National Park, and there are numerous options available elsewhere in the Park all summer long. Hebgen Lake is yet another option with large fish feeding on hatching Mayflies.

Late Season - (September/October)

As summer turns to fall, days shorten and cooler water temperatures trigger the emergence of late season mayflies like Blue-winged Olives and Mahogany Duns. Water levels are perfect for wading and the South Fork and Henry's Fork offer excellent and consistent opportunities for fishing dry flies to rising fish. Hatches can also be very good on the Firehole at this time of year. Streamer fishing can produce some of the best fishing of the year for trophy Brown Trout during this period. The smaller rivers remain a good option for those who enjoy wading with warm days producing excellent hopper fishing.
