It exits the south end of Priest Lake and flows south to the Pend Oreille River near the city of Priest River . The Upper Priest River , which is sometimes considered part of the Priest River proper, originates near the US-Canada border and flows south into Upper Priest Lake. The Priest River has three major tributaries. On

The lake was later named Priest Lake. Since the 1890s, logging has played an important role at Priest Lake. Logs were floated down

284-500: A large development of campgrounds, cabins, stores and service facilities were built just east of the bridge to support anglers. This area is now known as the Fishing Bridge Historic District. The 1937 bridge boasted pedestrian walkways on either side of the roadway to give more room to anglers. Angling in the river, at Fishing Bridge and in the lake, boomed during the 1950s and 1960s and over harvest caused

355-514: A major role in the restoration of the greenback ( O. v. stomias ) and Westslope cutthroat trout ( O. lewisi ) . The historic native range of cutthroat trout has been reduced by overfishing , urbanization and habitat loss due to mining, livestock grazing and logging. Population densities have been reduced and in some cases populations have disappeared though competition with non-native brook , brown, lake and rainbow trout, kokanee salmon , lake whitefish and mysis shrimp which were introduced in

426-402: A pristine variety of wildlife both in and around the lake. The standard bear, deer, and moose population that can be seen throughout northern Washington and Idaho is present about the lake, as well as a small population of grizzly bears. Priest Lake also has a large population of fish, including cutthroat trout , Kokanee , lake trout , and Dolly Varden trout . The largest lake trout caught in

497-547: A significant decline in the fishery. Consequently, in 1973, fishing was no longer permitted from Fishing Bridge. The Pyramid Lake strain of the Lahontan cutthroat trout, source of the 41-pound (19 kg) world record and native to Pyramid Lake, Lake Tahoe and the Truckee River, was brought to near-extinction in the two decades between the 1920s-40s from overharvest, introduced species and loss of spawning habitat. In

To facilitate further discussion without needing to resolve that detail, the panel used the term "uniquely identifiable evolutionary unit" (UIEU) to describe various evolutionary subunits within a species. In short, UIEUs are recognizable population groups that show independence in an evolutionary sense, but do not meet all the criteria to be considered full species. The evolutionary history of

639-695: A surviving population of a pure Pyramid Lake strain in a small headwaters stream on the Nevada-Utah border that had at some point around 1900 been introduced into the stream. In 1995, the U.S. Fish and Wildlife Service began rearing these fish in the Lahontan National Fish Hatchery in Gardnerville, Nevada . In 2006, the Pyramid Lake strain of Lahontan cutthroat trout were reintroduced into the lake. As Pyramid Lake has

The Leadville National Fish Hatchery produces 125,000–200,000 Snake River fine-spotted, greenback cutthroat and rainbow trout annually to support fishing in the Fryingpan and Arkansas River drainages and other Colorado waters. The Bozeman Fish Technology Center , formerly a cutthroat trout fish hatchery in Bozeman, Montana , plays

923-571: Is the Lahontan cutthroat trout ( O. h. henshawi ) . These fish average 8 to 9 in (20 to 23 cm) in small streams and 8 to 22 in (20 to 56 cm) in larger rivers and lakes. In ideal environments, the Lahontan cutthroat trout attains typical weights of 0.25 to 8 lb (0.11 to 3.63 kg). The world record cutthroat trout is a Lahontan at 39 in (99 cm) and 41 lb (19 kg). Cutthroat trout usually inhabit and spawn in small to moderately large, clear, well-oxygenated, shallow rivers with gravel bottoms. They are native to

Most populations stay in fresh water throughout their lives and are known as nonmigratory, stream-resident or riverine populations. The coastal cutthroat trout ( O. clarkii ) is the only cutthroat trout subspecies to coevolve through its entire range with the coastal rainbow trout ( O. m. irideus ). Portions of

1065-596: The Salmo s– brown trout ( S. trutta ) or Atlantic salmon ( S. salar ) of the Atlantic Basin . Thus, in 1989, taxonomic authorities moved the rainbow, cutthroat and other Pacific Basin trout into the genus Oncorhynchus . This single species ( O. clarkii) classification is now changed. Genetic, taxonomic, and geologic studies have determined that cutthroat trout should be divided into four distinct species, with each having multiple subspecies corresponding to

1136-606: The American Fisheries Society (AFS) in 2015, the Western Division of AFS (WDAFS) hosted an expert-panel workshop to evaluate the validity of the currently recognized subspecies, using evidence both for and against. The panel found the Behnke classification scientifically indefensible, and proposed an updated phylogeny and classification that aligns with the corpus of evidence. One specific detail

1207-627: The Cascade Range , the Great Basin and throughout the Rocky Mountains including southern Alberta . Some coastal populations of the coastal cutthroat trout ( O. c. clarkii ) are semi-anadromous, spending a few months in marine environments to feed as adults and returning to fresh water from fall through early spring to feed on insects and spawn. Cutthroat trout have the second-largest historic native range of North American trout;

1278-734: The Continental Divide in the upper Missouri River basin, upper Arkansas and Platte River basins and upper Yellowstone River basin, each which drain into the Atlantic basin via the Mississippi River (in 2005, researchers published a report stating that a natural distribution of ( O. mykiss ) , the Conchos trout, is also located in an Atlantic basin drainage ). Scientists believe that the climatic and geologic conditions 3–5 million years ago allowed cutthroat trout from

1349-615: The Gila trout and O. apache , the Apache trout in regions where their ranges overlap. Cutthroat trout are native to western North America and have evolved through geographic isolation into at least 25 genetically-recognizable lineages, each native to a different major drainage basin . Native cutthroat trout species are found along the Pacific Northwest coast from Alaska through British Columbia into northern California , in

1420-655: The Greater Yellowstone Ecosystem , the presence of lake trout ( Salvelinus namaycush ) in Yellowstone Lake in Yellowstone National Park has caused a serious decline in Yellowstone cutthroat trout ( O. v. bouvierii ) . Outbreaks of whirling disease in major spawning tributaries within the native ranges have also caused declines. Most subspecies of cutthroat trout are highly susceptible to whirling disease, although

1562-502: The Rocky Mountains , the area does get much more snow. Sixty inches (1.5 m) precipitation falls in the mountains around the lake each year with almost half of that coming in the form of snow. Cross country skiing and snowmobiling are popular winter activities. Cutthroat trout The cutthroat trout ( Oncorhynchus sp. ) is a group of four fish species of the family Salmonidae native to cold-water tributaries of

1633-691: The Snake River to migrate over the divide into the Yellowstone plateau via Two Ocean Pass . There is also evidence that Yellowstone Lake once drained south into the Snake River drainage. Evidence suggests that the westslope cutthroat trout was able to establish populations east of the divide via Summit Lake at Marias Pass which at one time connected the Flathead River drainage with the upper Missouri River drainage. Scientists speculate that there are several mountain passes associated with

1704-442: The U.S. Bureau of Fisheries . These hatcheries not only produced stocks of the Yellowstone cutthroat trout ( O. v. bouvierii ) for the park, but also took advantage of the great spawning stock of cutthroat trout to supply eggs to hatcheries around the U.S. Between the years 1901 and 1953 a total of 818 million trout eggs were exported from the park to hatcheries throughout the U.S. The Lahontan National Fish Hatchery operated by

1775-636: The United States was caught at Priest Lake, by a Spokane Washington man, Lyle McClure, in 1971 and weighed 57 lbs. 8 oz. The average lake trout ranges weighs in between 4 and 10 pounds. In 2006, Eurasian milfoil , an aquatic invasive species , was discovered in Priest Lake. Today, the lake's biggest draw is tourism. There are several large private resorts on the lake including Cavanaugh's Resort, Elkins Resort and Hill's Resort. Popular campgrounds include Indian Creek and Lionhead run by

1846-552: The alluvial or freestone streams that are typical tributaries of the rivers of the Pacific Basin, Great Basin and Rocky Mountains. Cutthroat trout spawn in the spring and may inadvertently but naturally hybridize with rainbow trout, producing fertile cutbows . Some populations of the coastal cutthroat trout ( O. c. clarkii ) are semi-anadromous . Several subspecies of cutthroat trout are currently listed as threatened in their native ranges due to habitat loss and

1917-439: The introduction of non-native species. Two subspecies, O. henshawi alvordensis and O. virginalis macdonaldi , are considered extinct . Cutthroat trout are raised in hatcheries to restore populations in their native range, as well as stock non-native lake environments to support angling. The cutthroat trout type species and several subspecies are the official state fish of seven western U.S. states. Cutthroat trout were

1988-404: The lake trout ( Salvelinus namaycush ) having the largest. Ranges of some subspecies, particularly the westslope cutthroat trout ( O. l. lewisi ) , have been reduced to less than 10 percent of their historic range due to habitat loss and introduction of non-native species. Although members of Oncorhynchus , the Pacific trout/salmon species, multiple lineages evolved populations east of

2059-403: The westslope cutthroat trout ( O. l. lewisi ) . As one of Lewis and Clark's many missions was to describe the flora and fauna encountered during their expedition, cutthroat trout were given the name Salmo clarkii in honor of William Clark. In 1836, the type specimen of S. clarkii was described by naturalist John Richardson from a tributary of the lower Columbia River , identified as

2130-494: The "Katpootl", which was perhaps the Lewis River , as there was a Multnomah village of similar name at the confluence . This type specimen was most likely the coastal cutthroat trout subspecies O. c. clarkii . Until the 1960s, populations of westslope cutthroat trout and Yellowstone cutthroat trout were lumped into one subspecies; Salmo clarkii lewisii . Biologists later split the group into two subspecies, christening

2201-719: The 1890s and sporadically in the early 20th century, but never established wild populations. A population of Yellowstone cutthroat trout purportedly has been established in Lake Huron . Cutthroat are routinely introduced by the Arizona Game and Fish Department into high mountain lakes in the White Mountains in the northeastern region of that state. Cutthroat trout require cold, clear, well-oxygenated, shallow rivers with gravel bottoms or cold, moderately deep lakes. Healthy stream-side vegetation that reduces siltation

2272-501: The 1890s, the Yellowstone cutthroat trout fishery in the Yellowstone River and Yellowstone Lake were well known and being promoted in national guidebooks. Fishing Grounds.—In the river at the lake outlet are the fishing grounds, about a mile from the hotel, while at many places between the lake and canyon excellent fishing is had from shore. The best results in the outlet are had from row boats; they can be rented from

2343-506: The 1970s, Pyramid Lake was stocked with Lahontan cutthroat trout strains still surviving in some nearby lakes, but they were not the large Pyramid Lake strain. Although the Pyramid Lake Paiute Tribe had been successful in re-establishing a cutthroat trout fishery on the reservation in Pyramid Lake, the cutthroat trout were not the large fish of the late 19th and early 20th century. In the late 1970, biologists discovered

2414-552: The Colorado River system was invaded from the Yellowstone and not the upper Arkansas River. More recently, an alternative theory demonstrates that cutthroat trout originated in the Bonneville Basin and then radiated outwards approximately 4 million years ago. This theory was based on their interpretation of the fossil record and DNA analysis. New evidence, particularly DNA analysis, is providing new insights into

2485-642: The Idaho Panhandle National Forests system. Most of the area on the east side of Priest Lake became school or endowment land for Idaho. In 1911, the state wanted to consolidate the three million acres of scattered parcels it received with statehood into a compact body to better manage timber sales effectively. It took 10 years of talks with the Secretary of Agriculture, a proclamation from President William Howard Taft, multiple court cases, much lobbying by timber interests, and an act of

2556-533: The Snake River drainage from U.S. government stocking operations in 1890, they were never officially introduced into the Yellowstone River drainage and their presence there is probably the result of accidental or illegal introductions. By 2000, the cutthroat trout population had declined to less than 10 percent of its early 20th century abundance. However, aggressive lake trout eradication programs have killed over 1 million lake trout since 1996, and

2627-420: The Snake River fine-spotted cutthroat trout appears to be resistant to the parasite. The most serious impact on the genetic purity of most cutthroat trout subspecies results from interspecific and intraspecific breeding resulting in hybrids that carry the genes of both parents. In inland populations, the introduction of rainbow trout from hatchery stocks have resulted in cutbow hybrids that continue to diminish

Several hiking trails circle the lake, also connecting to the Upper Priest Lake. In the wintertime, the larger resorts cater to cross-country skiing, snowshoeing, and snowmobiling. There is also a bed and breakfast - the historic Old Northern Inn , Coolin Motel, Nordman Resort (Nordman, Idaho), and three marinas, one located at

2769-477: The U.S. Congress for Idaho to receive title to the Kaniksu National Forest's eastside land in 1917. In 1950 these state lands to the east of Priest Lake were designated as Priest Lake State Forest. Later, in the 1980s, the State executed land exchanges with private companies that added nearly 13,000 acres (53 km ) to the state forest and resulted in its present boundaries. Priest Lake has

2840-607: The U.S. Fish and Wildlife Service exists to restore populations of the Lahontan cutthroat trout ( O. h. henshawi ) in Pyramid , Walker , Fallen Leaf , June , Marlette, and Gull Lakes and the Truckee River in California and Nevada. The hatchery produces about 300,000–400,000 Lahontan cutthroat trout fry annually. The Jackson National Fish Hatchery produces around 400,000 Snake River fine-spotted cutthroat trout (which

2911-909: The Westslope cutthroat trout's ( O. lewisi ) range overlap with the Columbia River redband trout ( O. m. gairdneri ) , but the majority of its native range is in headwater tributary streams above major waterfalls and other barriers to upstream migration. At least three subspecies are confined to isolated basins in the Great Basin and can tolerate saline or alkaline water. Cutthroat trout are opportunistic feeders . Stream-resident cutthroat trout primarily feed on larval , pupal and adult forms of aquatic insects (typically caddisflies , stoneflies , mayflies and aquatic dipterans ), and adult forms of terrestrial insects (typically ants , beetles , grasshoppers and crickets ) that fall into

2982-404: The alluvial or freestone streams typical of tributaries of the Pacific Basin, Great Basin and Rocky Mountains. They spawn in the spring, as early as February in coastal rivers and as late as July in high mountain lakes and streams. Spawning begins when water temperatures reach 43 to 46 °F (6 to 8 °C). Cutthroat trout construct a redd in the stream gravel to lay eggs. The female selects

3053-428: The back. Cutthroat trout can generally be distinguished from rainbow trout by the presence of basibranchial teeth at the base of tongue and a maxillary that extends beyond the posterior edge of the eye. Depending on subspecies, strain and habitat, most have distinctive red, pink, or orange linear marks along the underside of their mandibles in the lower folds of the gill plates. These markings are responsible for

3124-431: The closely related rainbow trout, producing fertile hybrids commonly called " cutbows ". This hybrid generally bears similar coloration and overall appearance to the cutthroat trout, usually retaining the characteristic orange-red slash. Cutbow hybrids often pose a taxonomic difficulty when trying to distinguish any given specimen as a rainbow or cutthroat trout. In addition, cutthroat trout may hybridize with O. gilae ,

3195-1056: The common name "cutthroat", first given to the trout by outdoor writer Charles Hallock in an 1884 article in The American Angler . These markings are not unique to the species. Some coastal rainbow trout ( Oncorhynchus mykiss irideus ) and Columbia River redband trout ( O. m. gairdneri ) populations also display reddish or pink throat markings. At maturity, different populations and subspecies of cutthroat trout can range from 6 to 40 inches (15 to 102 cm) in length, depending on habitat and food availability. Sea-run forms of coastal cutthroat trout average 2 to 5 pounds (0.9 to 2.3 kg). The length and weights of mature inland forms vary widely depending on their particular environment and availability of food. Stream-resident fish are much smaller, 0.4 to 3.2 ounces (11 to 91 g), while lacustrine populations have attained weights ranging from 12 to 17 lb (5.4 to 7.7 kg) in ideal conditions. The largest cutthroat trout subspecies

3266-413: The cutthroat trout is complex and not fully agreed upon by all scientists. What is known is that cutthroat trout were present in the then-forming Lahontan basin 10 million years ago. This, coupled with new information about drainage patterns in western rivers, suggests that the interior radiation and colonization pathways of the cutthroat trout may be different than what was previously thought. Previously,

3337-450: The distinctive red coloration on the underside of the lower jaw . The specific name clarkii was given to honor explorer William Clark , coleader of the Lewis and Clark Expedition . Cutthroat trout usually inhabit and spawn in small to moderately large, clear, well- oxygenated , shallow rivers with gravel bottoms. They reproduce in clear, cold, moderately deep lakes. They are native to

3408-592: The early 19th century fur trappers established trade with the native Kalispel tribe. In the 1840s Jesuit priest Pierre-Jean DeSmet began working with the Kalispel tribe along the nearby Pend Oreille River. From the tribe's information about Priest Lake, De Smet was able to create a map and named the lake Roothaan Lake for one of his superiors in Rome. The name would not stick though and in 1865 Captain John Mullan ,

3479-530: The early 20th century. Managers implemented catch and release , which required anglers to return their catches to the lake, and they terminated hatchery operations in the park, which allowed the cutthroat trout to recover. Then, in 1994, park officials discovered lake trout ( Salvelinus namaycush ) in Yellowstone Lake. Although lake trout were established in Shoshone , Lewis and Heart Lakes in

3550-454: The evolutionary lineages found within major river basins, except for the Coastal cutthroat trout. Behnke in his salmon and trout handbook of 2002 recognized 14 subspecies of cutthroat trout that are each native to a separate geographic area. Not all of them were scientifically described, and different views on the taxonomic identities have been presented. During the annual meeting of

3621-429: The extinction of the yellowfin cutthroat trout ( O. v. macdonaldi ) and Alvord cutthroat trout ( O. h. alvordensis ) subspecies to the introduction of non-native rainbow trout. The population at the core of the Yellowstone cutthroat trout's native range, in Yellowstone Lake, declined significantly in the 1960s due to overharvest of mature cutthroat trout by anglers, as well as overharvesting of eggs by hatcheries in

3692-596: The first New World trout encountered by Europeans when in 1541, Spanish explorer Francisco de Coronado recorded seeing trout in the Pecos River near Santa Fe, New Mexico . These were most likely Rio Grande cutthroat trout ( O. v. virginalis ) . The species was first described in the journals of explorer William Clark from specimens obtained during the Lewis and Clark Expedition from the Missouri River near Great Falls, Montana , and these were most likely

3763-415: The first evolutionary theory, based on the work of David Starr Jordan and later Robert J. Behnke, proposed that an ancestral cutthroat trout from Asia entered North America and dispersed inland through the Columbia River basin. The formation of Shoshone Falls on the Snake River then isolated groups of trout, leading to the variety of subspecies seen today. Behnke later modified this theory, suggesting that

3834-462: The fly angler. From Alaska to Northern California, coastal cutthroat trout in sea-run, resident stream and lacustrine forms are sought by anglers. Puget Sound in Washington is a stronghold of sea-run cutthroat trout fishing with its many tributaries and protected saltwater inlets and beaches. Fly anglers search for sea-run cutthroat trout along beaches, river mouths and estuaries year round. In

3905-534: The genetic purity of many cutthroat trout subspecies. The introduction of hatchery-raised Yellowstone cutthroat trout into native ranges of other cutthroat trout subspecies, particularly the westslope cutthroat trout, has resulted in intraspecific breeding and diminished genetic purity of the westslope subspecies. As such, populations of genetically pure westslope cutthroat trout are very rare and localized in streams above barriers to upstream migrations by introduced species. Fisheries biologist Robert J. Behnke attributes

3976-747: The headwaters of the Colorado River drainage and Arkansas/Platte River drainages that would have allowed migration of cutthroat trout east of the divide. Cutthroat trout have been introduced into non-native waters outside their historic native range, but not to the extent of the rainbow trout ( O. mykiss ) . Within the native range of the Yellowstone cutthroat trout, U.S. Fisheries Bureau and National Park Service authorities introduced Yellowstone cutthroat trout into many fishless lakes in Yellowstone National Park . Cutthroat trout were introduced into Lake Michigan tributaries in

4047-570: The hope is that this will lead to a restoration of cutthroat numbers. Cutthroat trout co-exist with lake trout in Heart Lake , an isolated back-country lake at the head of the Heart River that gets little angling pressure. Cutthroat trout are prized as a gamefish, particularly by fly anglers. They are regulated as a gamefish in every state and province they occur in. From the Yellowstone cutthroat trout fishery in Yellowstone National Park,

This forest reserve subsequently evolved into the Kaniksu National Forest – which has been recently incorporated into

4260-540: The late 19th and early 20th centuries. Scientists believe the westslope cutthroat trout will eventually be extirpated from the large lakes in Western Montana due to the trophic cascades resulting from lake trout and mysis shrimp introductions. The most serious current threats to several subspecies are interspecific breeding with introduced rainbow trout, creating hybrid cutbows, and intraspecific breeding with other introduced cutthroat trout subspecies.

What is known is that repeated glacial and interglacial periods that would have caused repeated fracturing and isolation of cutthroat trout populations, eventually resulting in the different cutthroats found today. Throughout their native and introduced ranges, cutthroat trout vary widely in size, coloration and habitat selection. Their coloration can range from golden to gray to green on

One side favored subspecies as a valuable taxonomic rank , because they represent important information about their evolutionary and ecological history that should be recognized to preserve biodiversity. The other side disagreed, arguing that subspecies do not necessarily align with actual evolutionary units, and are simply designations of lineages within

4686-415: The range of the bull trout ( Salvelinus confluentus ) the cutthroat trout is a forage fish for the piscivorous bull trout. Various subspecies of cutthroat trout are raised in commercial, state and federal hatcheries for introduction into suitable native and non-native riverine and lacustrine environments. In the early 20th century, several hatcheries were established in Yellowstone National Park by

In 1902, anticipating the completion of the east entrance road from Cody, Wyoming, Captain Hiram M. Chittenden supervised the construction of the first "Fishing Bridge" across the outlet of Yellowstone Lake. Fishing Bridge was rebuilt in 1919, and reconstructed in 1937, primarily to accommodate vehicle traffic. Between 1916 and 1931,

4828-777: The site for and excavates the redd. Females, depending on size, lay between 200 and 4,400 eggs. Eggs are fertilized with milt (sperm) by an attending male. Eggs hatch into alevins or sac fry in about a month and spend two weeks in the gravel while they absorb their yolk sack before emerging. After emergence, fry begin feeding on zooplankton . Juvenile cutthroat trout typically mature in three to five years. Lake-resident cutthroat trout are usually found in moderately deep, cool lakes with adequate shallows and vegetation for good food production. Lake populations generally require access to gravel-bottomed streams to be self-sustaining, but occasionally spawn on shallow gravel beds with good water circulation.
