Question: Which State's fish was discovered at the base of Colter Falls?

full_context: Document 1: Rainbow Falls (Missouri River): Rainbow Falls (originally "Handsome Falls") is a waterfall on the Missouri River in Great Falls, Montana, just upstream from Crooked Falls and downstream from Colter Falls and Rainbow Dam. It is 47 feet (14m) high and 1,320 feet (402.3m) wide. The waterfall is part of the five Great Falls of the Missouri. The river spills over a sheer ledge of sandstone in the Kootenai Formation, forming the falls. The falls used to flow with a great deal of force year-round. In 1914 the river shortly upstream was dammed for hydroelectric power by the Rainbow Dam, which forms a run-of-the-river reservoir. As a result, the falls can almost totally dry up in the summer with only a few narrow strips of water trickling down its face. A railroad bridge crosses the river directly above the falls.
Document 2: Great Falls (Catawba River): The Great Falls of the Catawba River mark the point at which the river encounters a series of rapids while coursing across the Piedmont Plateau on the border of Lancaster County, South Carolina, and Chester County, South Carolina, near the town of Great Falls. Prior to the creation of the Fishing Creek Reservoir and other artificial lakes by Duke Power, the falls were a major landmark on the river. The rapids could be heard from long distances away, while a major pre-Columbian trading path ran near the left bank. Historically the Great Falls of the Catawba were approximately 4 miles long, with a total elevation drop of 121 feet. (The word "falls" was an 18th-century appellation, when any river rapids and vertical waterfalls alike were both referred to as falls.) The creation of the dams at Great Falls, South Carolina has resulted in the top 2 miles of it being completely dry (dewatered) except during times of very high flow. The bottom portion of historical Great Falls is drowned by Cedar Creek dam, another hydroelectric project. As of 2006, interest groups have formed in the Carolinas to restore the Great Falls by altering the dam and restoring flow to the dewatered stretch of Great Falls as part of a major restoration project of the Catawba River. As of 2007, a new licensing arrangement has been agreed to by Duke Energy and several interested parties.
Document 3: Kautz Creek Falls: Kautz Creek Falls is a waterfall on Kautz Creek in the Mount Rainier National Park in the state of Washington. It was formed when the Kautz Glacier retreated in the last 50 years, creating a series of long and slender cascades totaling about 400 ft in height down a tall glacial cliff, with a highest drop of 150 ft . The falls consist of two parts, each with two distinct tiers. One of these parts flows from the upper lobe of the Kautz Glacier and disappears under the lower lobe. The water flowing over this stage is generally clear. As the water passes underneath the lower lobe, however; it has a muddy appearance caused by glacial moraine, which explains the muddy appearance of Kautz Creek.
Document 4: Salmo: Salmo is a genus of fish in the salmon family Salmonidae that includes the European species of salmon and trout, among them the familiar Atlantic salmon "Salmo salar" and the brown trout "Salmo trutta". The natural distribution of "Salmo" also extends to Northern Africa and to Western Asia around the Black Sea basin. The single "Salmo" species naturally found in the Atlantic North America is the Atlantic salmon, whereas the salmon and trout of the Pacific basin belong to another genus, "Oncorhynchus". The generic name "Salmo" derives from the Latin "salmō" (salmon). The number of distinct species and subspecies in "Salmo" is a debated issue. Atlantic salmon and brown trout are widespread species, while most of the other taxa are narrowly distributed forms endemic to single watersheds.
Document 5: Golden trout: The California golden trout, or simply the golden trout ("Oncorhynchus mykiss aguabonita"), is a subspecies of the rainbow trout native to California. The golden trout is native to Golden Trout Creek (tributary to the Kern River), Volcano Creek (tributary to Golden Trout Creek), and the South Fork Kern River. It is the state fish of California.
Document 6: Black Eagle Dam: Black Eagle Dam is a hydroelectric gravity weir dam located on the Missouri River in the city of Great Falls, Montana. The first dam on the site, built and opened in 1890, was a timber-and-rock crib dam. This structure was the first hydroelectric dam built in Montana and the first built on the Missouri River. The dam helped give the city of Great Falls the nickname "The Electric City." A second dam, built of concrete in 1926 and opened in 1927, replaced the first dam, which was not removed and lies submerged in the reservoir. Almost unchanged since 1926, the dam is 782 ft long and 34.5 ft high, and its powerhouse contains three turbines capable of generating seven megawatts (MW) of power each. The maximum power output of the dam is 18 MW. Montana Power Company built the second dam, PPL Corporation purchased it in 1997 and sold it to NorthWestern Corporation in 2014. The reservoir behind the dam has no official name, but was called the Long Pool for many years. The reservoir is about 2 mi long, and has a storage capacity of 1,710 acre.ft to 1,820 acre.ft of water.
Document 7: Environmental issues with salmon: Salmon population levels are of concern in the Atlantic and in some parts of the Pacific. Salmon fishery stocks are still abundant, and catches have been on the rise in recent decades, after the state initiated limitations in 1972. Some of the most important Alaskan salmon sustainable wild fisheries are located near the Kenai River, Copper River, and in Bristol Bay. Fish farming of Pacific salmon is outlawed in the United States Exclusive Economic Zone, however, there is a substantial network of publicly funded hatcheries, and the State of Alaska's fisheries management system is viewed as a leader in the management of wild fish stocks. In Canada, returning Skeena River wild salmon support commercial, subsistence and recreational fisheries, as well as the area's diverse wildlife on the coast and around communities hundreds of miles inland in the watershed. The status of wild salmon in Washington is mixed. Out of 435 wild stocks of salmon and steelhead, only 187 of them were classified as healthy; 113 had an unknown status, 1 was extinct, 12 were in critical condition and 122 were experiencing depressed populations.
Document 8: Ptychocheilus: Squawfish or pikeminnows are cyprinid fish of the genus Ptychocheilus consisting of four species native to western North America. Voracious predators, they are considered an "undesirable" species in many waters. This is largely due to the species' perceived tendency to prey upon small trout and salmon. First known in western science by the common name Columbia River Dace, the four species all became lumped under the offensive name "squawfish." In 1999, the American Fisheries Society adopted "pikeminnow" as the name it recommends, because Native Americans considered "squawfish" offensive.
Document 9: Alvord cutthroat trout: The Alvord cutthroat trout, "Oncorhynchus clarki alvordensis", was a subspecies of cutthroat trout. It was known only from Trout Creek in Oregon and Virgin Creek in Nevada, although it may have lived in several of the larger Alvord Basin streams during recent times. It was native to spring-fed creeks that ran down to Alvord Dry Lake in southeast Oregon, which was a large lake during the ice ages and an isolated drainage, part of the Great Basin today. This is one of the two cutthroat trout taxa considered extinct because all known populations are hybridized with rainbow trout which were introduced into streams in the Alvord basin in the 1920s, resulting in cutbows.
Document 10: Sheepheaven Creek redband trout: The Sheepheaven Creek redband trout is a local Californian variety of the rainbow trout ("Oncorhynchus mykiss"), a freshwater fish in the Salmonidae family. It is considered either a distinct western form of the McCloud River redband trout (subspecies "Oncorhynchus mykiss stonei"), or a subspecies of its own, which has not been scientifically named and described yet. It is native to Sheepheaven Creek, Siskiyou County, California, United States. It has been transplanted into Swamp Creek in 1972 and 1974 and into Trout Creek in 1977. They can now be found in both locations. Sheepheaven Creek redband are found to be the most distinct among all other trout groups, and therefore has been suggested to merit recognition as a new subspecies. They have the fewest gill rakers of any western trout.
Document 11: Puget Sound salmon recovery: Puget Sound salmon recovery is a collective effort of federal, state and local authorities and non-profit coalitions of universities, scientists, business and industry aimed at restoring Pacific salmon and anadromous forms of Pacific trout ("Oncorhynchus") within the Puget Sound region. The Puget Sound lies within the native range of the Pacific Salmon ("Oncorhynchus") and two sea-run forms of Pacific trout, the coastal rainbow trout ("O. mykiss irideus") or steelhead and coastal cutthroat trout ("O. clarki clarki"). Populations of "Oncorhynchus" have seen significant declines since the middle of the 19th century due to over fishing, habitat loss, pollution and disease. Salmon species residing in or migrating through the Puget Sound to spawning streams include Chum ("O. keta"), Coho ("O. kisutch"), Chinook ("O. tshawytscha"), Sockeye ("O. nerka"), and Pink salmon ("O. gorbuscha"). Pacific salmon require freshwater rivers for spawning and most major tributaries of the Puget Sound have salmon, steelhead and cutthroat trout spawning runs.
Document 12: Thompson Falls State Park: Thompson Falls State Park is a Montana state park located near Thompson Falls, Montana. Located on the banks of the Clark Fork River in western Montana, the park is 36 acres in size, and includes a campground, two boat launches, a kids' fishing pond, and riverside trail. The park is fully open April 1 to November 30; walk-in day use is permitted the rest of the year.
Document 13: Rainbow Dam: Rainbow Dam is a hydroelectric dam on the Missouri River, 29 ft high and 1055 ft long, located six miles northeast of Great Falls in the U.S. state of Montana. The dam is named for the downstream Rainbow Falls, a 45 ft waterfall that is the third of the five Great Falls of the Missouri. Built in 1910, the dam furnishes water to an eight-unit hydroelectric plant with a capacity of 36 megawatts. As the dam's power plant is located over a half-mile downstream, the flow of water over Rainbow Falls and downstream Crooked Falls is significantly reduced during the dry season. The water from the penstocks re-enters the river a few hundred yards east of Crooked Falls. Montana Power Company acquired the dam when it was founded in 1912, PPL Corporation purchased it in 1997 and sold it to NorthWestern Corporation in 2014.
Document 14: Colter Falls: Colter Falls, also Coulter Falls, (4.3m) waterfall, nearly 0.5 mi in width, part of the Great Falls of the Missouri, on the Missouri River in north-central Montana. Downstream of Colter Falls lies Rainbow Falls, and upstream is Black Eagle Falls. The Lewis and Clark Expedition was known to discover Westslope cutthroat trout at the base of the falls. The falls is now flooded in the impoundment behind Rainbow Dam. As Rainbow Dam's reservoir is a run-of-the-river reservoir, it rarely is emptied, so the falls is rarely seen even in extreme drought. The falls was named by Paris Gibson, founder of the city of Great Falls, Montana, while they were not named by Lewis and Clark, who measured it at "6 feet 7 inches".
Document 15: Westslope cutthroat trout: The westslope cutthroat trout ("Oncorhynchus clarki lewisi"), also known as the black-spotted trout, common cutthroat trout and red-throated trout is a subspecies of the cutthroat trout ("Oncorhynchus clarki") and is a freshwater fish in the salmon family (family Salmonidae) of order Salmoniformes. The cutthroat is the Montana state fish. This subspecies is a "species of concern" in its Montana and British Columbia ranges and is considered "threatened" in its native range in Alberta.
