Book excerpt: Under the direction of the inventory and monitoring component of the Natural Resource Challenge, National Park Service biologists in Yellowstone National Park (YNP) began a three-year inventory of the Snake River watershed in 2004. Although the Snake River drainage is the third-largest in the park, less than half of the main stem and few of the tributaries had ever been sampled in a systematic manner. Not only does the Snake River contain the most diverse assemblage of native fish species in the park, but two of YNP's three types of cutthroat trout (Oncorhynchus clarki) also reside there. Although Yellowstone cutthroat trout (O. c. bouvieri) and Snake River fine-spotted cutthroat trout (O. c. subsp.) exhibit observable phenotypic differences in terms of their spotting patterns, considerable debate about their true historic distribution and taxonomic status has occurred because the two subspecies have been nearly indistinguishable when examined meristically or genetically. As a cooperative effort with U.S. Forest Service biologists of the Bridger-Teton National Forest, we sampled the watershed with the following objectives: (1) to conduct a systematic survey of the Snake River tributaries and determine the distribution of the two types of cutthroat trout there; (2) to describe population characteristics of native and non-native fish species; and (3) to obtain samples for genetic analyses in order to compare field identification with laboratory results of individual genetic identity. To accomplish these objectives, we subdivided the main stem into more than 30 sections of 2 km each. Tributary sample sections were much shorter; each section was one-tenth of that stream's total perennial length. In each survey section, the survey crew electrofished 50-100 m of the stream or until a representative sample was obtained. We attempted to catch at least three cutthroat trout longer than 150 mm from each sample reach, as individuals shorter than this length often display indistinct spotting patterns. Mountain whitefish (Prosopium williamsoni) were the most abundant species captured in the main stem, but their distribution was restricted to areas downstream from the confluence with the Heart River. Cutthroat trout and mottled sculpin (Cottus bairdi) were captured throughout the watershed. However, the seven fish identified in the field as fine-spotted cutthroat trout were restricted to the lower sections of the main stem. Most of the other native species, and the few brown trout (Salmo trutta) and brook trout (Salvelinus fontinalis) found in this survey, were collected in the same sections as the mountain whitefish. The Snake River fine-spotted cutthroat trout were the largest individuals captured during the survey; several were longer than 400 mm. Many of the other cutthroat trout were younger fish between 100 and 125 mm long. Consequently, most of the cutthroat trout caught in the main stem could not be definitively identified in the field as either the fine-spotted form or the large-spotted Yellowstone cutthroat trout. In most of the tributaries, only Yellowstone cutthroat trout and mottled sculpin were caught. Cutthroat trout, mountain whitefish, and five non-game species were captured from the Heart River. Typically, the cutthroat trout that could be identified in the tributaries were smaller and exhibited different coloration than the adult fish from the main stem.

Available in PDF, EPUB and Kindle. Book excerpt: Normal 0 The Yellowstone River within Yellowstone National Park is the world’s best Yellowstone Cutthroat Trout fishery. The Yellowstone River within the park can be divided into three-distinctive sections. The headwaters of the Yellowstone River begin on the east side of the Continental Divide from the Shoshone Mountain Range of Wyoming. The Yellowstone River flows northerly into Yellowstone Lake, elevation 7,733-feet. Yellowstone Lake is the largest lake at this elevation on the continent. The mid-section of the Yellowstone River, which flows out of Yellowstone Lake downstream to the Upper Falls of the Yellowstone River lies the world renown section of the Yellowstone River where hundreds of people flock to on July 15th “Opening Day” every year. The lower section, below the Lower Falls of the Yellowstone River flows through the Canyon of the Yellowstone downstream to the Yellowstone National Park Boundary, by the town of Gardner, Montana is probably the least fished section of the Yellowstone River. The fishing seasons opens July 15th every year which allows the Yellowstone Cutthroat Trout Brood Stock to spawn and gives the Yellowstone Cutthroat Fry time to emerge from the redds before the wade fishermen can step on them. The headwaters and mid-section of the Yellowstone River are the major spawning areas for the Yellowstone Lake Cutthroat Trout Fishery. The Yellowstone River is a premiere dry fly fishing river with prolific hatches of May Flies: Early Blue-Winged Olive (Baetis tricaudatus), Late Blue-Winged Olive (Baetis parvus), Little Western Blue-Winged Olive (Ephemerella margarita), Western Green Drake (Drunella grandis), Pale Morning Dun (Ephemerella inermis and Ephemerella infrequens) and Small Western Green Drake (Ephemerella flavilinea); Stone Flies: Salmon Fly (Pteronarcys californica), Western Big Golden Stone Fly (Calineuria californica), Western Medium Golden Brown Stone Fly (Isoperla sp.) and Little Yellow Stone Fly (Alloperla pallidula); Caddis: Green Sedge (Ryacophila sp.), Little Tan Short Horn Sedge (Glossosoma sp.), Spotted Sedge (Hydropsyche sp.) and Giant Orange Sedge (Dicosmoecus sp.).

Available in PDF, EPUB and Kindle. Book excerpt: Normal 0 The Yellowstone Drainage supports the largest inland population of native Yellowstone Cutthroat Trout on Earth. The Yellowstone Cutthroat Trout is considered a shared resource in Yellowstone Lake: Grizzly Bears, Black Bears, Bald Eagles Golden Eagles, Pelicans, Osprey, Great Blue Herons, Kingfishers, Gulls, Grebes, Terns, Loons, Mergansers, Mink, Otters, Wolves and Coyotes prey upon Yellowstone Cutthroat Trout. In the Yellowstone drainage 200,000-pounds of Yellowstone Cutthroat Trout are eaten each year by these animals and birds. Yellowstone Lake is the largest fresh water lake in the United States above 7,000-feet, it’s altitude is 7,733-feet above sea level. The Yellowstone Lake encompasses 136 square miles, it is 20-miles long, 14-miles wide and has 110-miles of shoreline. Yellowstone Lake is 320-feet deep at its deepest point. The average depth is 139-feet. Yellowstone Cutthroat Trout generally inhabit the upper 60-feet because their food source rarely occurs below that depth. The average surface temperature in August is 60 degrees Fahrenheit; the bottom the temperature never rises above 42 degrees Fahrenheit. The serenity of Yellowstone Lake can suddenly change with afternoon thunderstorms and their accompanying winds. These winds can routinely produce 3-foot waves or larger within minutes on Yellowstone Lake. With water temperatures averaging 41 degrees Fahrenheit you can develop hypothermia quickly if your vessel capsizes. Fishing season in Yellowstone Lake opens June 15th each year, usually! There are 124-tributaries the Yellowstone Cutthroat Trout use for spawning including the largest tributary, the Yellowstone River. These spawning tributaries open July 15th each year, however some remain closed all year. The use of all lead fishing tackle is band; fisherman must use Non-Toxic alternative products. The West Thumb geyser basin area has intense heat in the lake sediments, which indicate a shallow thermal system underlying this more recent caldera. If the lake level should fall just a few feet, an immense steam (hydrothermal) explosion could occur here. Mary Bay and Indian Pond now show evidence of these craters.

This book was released on 1959 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research to appraise current fish management practices and to develop improved practices was carried on in the Yellowstone National Park portion of the Madison River system from 1953 to 1957. The physical, chemical and biological characteristics of the Firehole, Gibbon and Madison Rivers are described. Experiements designed to test the value of fingerling and adult stocking resulted in the conclusion that fingerling stocking of brown and rainbow trout does not contribute to the fishery substantially and that adult stocking is of greatest value only in the season of stocking. Examination of scales showed that hatchery fish are readily distinguishable from wild fish. There were no differences in growth rates of wild fish in different years for different rates of stocking of hatchery fish. The brown and rainbow trout populatons are not affected adversely by heavy introduction of hatchery fingerlings of each species or of adult rainbows. Brook and brown trout and whitefish are substantially underfished.

This book was released on with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Normal 0 Rattlesnake Creek is a small wadeable creek which runs through the Rattlesnake Wilderness and Recreation Area for approximately 23 miles and flows into the Clarkfork River in downtown Missoula, Montana. Until 1983, Rattlesnake Creek was used as Missoula's municipal water supply. In 1940 the creek was closed to fishing above the water supply reservoir, which is located 2.5 miles upstream from the mouth. Due to an outbreak of Giardia in 1983, Missoula began using wells as its sole source of water thus allowing recreational use of the water for the first time in 45 years. In the winter of 1984-85 the Montana Fish and Game Commission opened Rattlesnake Creek to catch and release fishing above Beeskove Creek. A six-mile hike limits access to the catch and release fishing section. No vehicle travel is allowed but mountain bikers for easier access can use an old fire road. The current study on Rattlesnake Creek was designed to obtain more intensive data than otherwise possible by state or federal agencies. This report summarizes the results of research initiated in the spring of 1985 to evaluate the population dynamics of the unfished cutthroat fishery below Beeskove Creek and to evaluate the effects of special regulations in the area above Beeskove Creek. The Study Area The upper Rattlesnake Creek drainage is located 5.6 miles (8.3 km) north of Missoula in western Montana (Figure 1). The drainage encompasses approximately 81.3 square miles (21,053 ha), most of which is owned by the United States Forest Service. Rattlesnake Creek originates on the flanks of McLeod and Triangle peaks, flowing south-southwest to its confluence with the Clark Fork of the Columbia River at Missoula (Figure 1). In 23.3 miles (37.0 km), from source to mouth, the creek descends 5291.0 ft. (1613 m) for a mean gradient of 4.3%. Of the nine perennial tributaries, three (Wrangle, Lake, and High Falls creeks) originate from glacial lakes; the remaining 6 (Porcupine, East Fork of Rattlesnake, Beeskove, Pilcher, Fraser and Spring creeks) originate from springs. Numerous intermittent streams also feed Rattlesnake Creek. More than 40 lakes are located in the upper drainage mostly on the west side. Geologic studies indicate that the parent materials include argillites, quartzites, and limestone of the Precambrian Belt series as well as Cambrian shales and limestones (Nelson & Dobell,1961). The watershed is characterized by relatively high peak discharge per unit area, a disproportionately large amount from the upper elevations (Van der Poel, 1979). Rattlesnake Creek is a 3rd order stream, which flows through a fairly steep valley. The valley bottom is an open pine-larch forest; cottonwoods and shrubs line the creek. Occasionally the valley bottom opens up into small, grassy meadows. Higher in the drainage the valley is increasingly timbered and steep. A stable natural character generally persists throughout the drainage. The substrate of Rattlesnake Creek is mostly gravel and cobble with a few boulders. The average flow is approximately 45-50 cubic feet per second. Although the creek does not currently supply Missoula with water, it is primarily managed as a watershed and secondarily managed as a recreational area (USFS Management Plan, 1984). The possibility of building a small filtration plant on the creek and again using the water for Missoula's municipal water supply is being discussed. A small water company dam already exists 2.5-miles upstream from the mouth of Rattlesnake Creek. The area would be the most probable site for a filtration plant. The water company dam prevents all upstream fish migration from the Clarkfork River.
