SECTORS

Sector 1: Snake River (bank)
The Henry’s Fork is one of the most storied and scenic rivers in the United States. At over 175 kilometers the Henry’s Fork contains good numbers of trout and whitefish throughout its length. Some stretches of the river contain as many as 4,000 trout per kilometer. The Henry’s is incredibly diverse starting as a primarily spring fed river it transforms to tailwater stretches as it goes through various impoundments. Some of the stretches are among the most famous in the world; Box Canyon, Railroad Ranch, Cardiac Canyon and numerous world class float and wade fishing segments before it joins the South Fork of the Snake River. All age classes of fish can be found in the river. Above Mesa Falls the river contains mostly Rainbow Trout and Mountain Whitefish, with some Brook trout. Below the falls Brown Trout become common. There will be water available for practice on the river in advance of the championship. Target Fish Species: Brook trout, Brown Trout, Cutthroat Trout, Rainbow trout, Cutbows and Mountain Whitefish.

Sector 2: Hebgen Lake (boat fishing)
Fed primarily by the Madison River as it exits Yellowstone National park, Hebgen is perhaps the highest quality trout lake in all of Montana. The lake covers about 12500 surface acres. Famous for its summer Gulper fishing there are plenty of dry fly fishing opportunities on the lake. Large Brown and Rainbow Trout with many exceeding 40 cm populate the lake. Mountain Whitefish can also be caught in the lake and there are possibilities to catch remnant Arctic Grayling and Cutthroat. Championship fishing will be limited to the Madison Arm of the lake. Because of the scarcity of rental boats, all practice will be coordinated by the organizer. Practice times will be limited and scheduled. Target Fish Species: Arctic Grayling, Brown Trout, Cutthroat Trout, Rainbow trout, Mountain Whitefish.

Sector 3: Teton River (bank fishing)
The Teton River in eastern Idaho is a renowned coldwater fishery and one of the last strongholds for native Yellowstone cutthroat trout in the Greater Yellowstone Ecosystem. It originates on the west slope of the Teton Mountains. It flows roughly 70 miles through Teton Valley, then through a canyon section, before joining the Henrys Fork of the Snake River near Rexburg. Key fish species include: Native Yellowstone cutthroat trout (the signature/primary species; typically 12–16 inches, with some larger; catch-and-release only); Rainbow trout (common, especially lower river); Brook trout (common in upper reaches/tributaries); Brown trout (present, especially canyon and lower sections; some larger fish); Mountain whitefish (native and common). It is famous for its high-quality wild-trout fishery, excellent dry-fly fishing (hatches of mayflies, caddis, stoneflies, and hoppers), scenic backdrop of the Teton Range, and status as a stronghold for native Yellowstone cutthroats amid generally high-quality habitat. The upper meadow stretches offer accessible, rising fish, while the canyon holds bigger trout and is managed primarily as a wild trout fishery. Target Fish Species: Brown Trout, Cutthroat Trout, Rainbow trout, Mountain Whitefish.

Sector 4: Sheridan Lake (boat fishing)
One of the premier trout lakes in North America, Sheridan is a private lake with restricted access. The lake covers about 250 surface acres and has an average depth of 3 meters with some areas as deep as 8 meters. The lake is stocked with primarily Kamloops Rainbow Trout. These are hard fighting and fast growing fish. It is possible to catch Cutthroat Trout in the lake as well. Most fish will exceed 35 cm in length with some achieving 50 cm or more. There will be no practice available at the lake in preparation for the championship. Target Fish Species: Cutthroat Trout, Rainbow trout.

Sector 5: Grey’s River (bank fishing)
The Grey’s River is the primary drainage river for the Wyoming Range in western Wyoming. 100 kilometers long the Grey’s ends in the Snake River as it enters Palisades Reservoir. Made up of primarily small snow melt creeks, the river experiences high spring and early summer flows that make the river habitat perfect for the native species. The Greys River presents perhaps the best opportunity to catch Snake River Fine Spotted Cutthroat Trout and Mountain Whitefish in good numbers. Many of both species will exceed 40 cm in length. There will be water available for practice on the river in advance of the championship. Target Fish Species: Brook trout, Brown Trout, Cutthroat Trout, Rainbow trout, Cutbows and Mountain Whitefish.
