For first time in nearly a century, a rare California trout species will swim in a mountain creek that is its native habitat, marking a major milestone that conservationists hope will le to a thriving population and removal of its threatened status. About 30 Paiute cutthroat trout will be plucked Wednesday from Coyote Valley Creek in eastern Sierra Neva wilderness and hauled in cans strapped to pack mules about 2 miles (3.2 kilometres) west into Long Valley. State and federal researchers will be on hand as fish are dumped into a stretch of Silver King Creek at around 8,000 feet (2,438 meters) elevation, where shimmering species glided through cold water for thousands of years below a waterfall before y started disappearing in 1920s.

Eye-catching species 

Paiute are eye-catching for ir “purplish iridescent hue” and a lack of body spots that mark many of 14 subspecies of cutthroat trout, said Bill Somer, senior environmental scientist with California Department of Fish and Wildlife. color is kind of hard to describe and really hard to photograph,” he said. “You can only see how unique y are if you catch m and hold m in your hand.”

Upgred to threatened status in 1975

homecoming in Alpine County is culmination of deces of restoration and conservation work that got a boost in 1967, when Paiute cutthroat received federal protection as one of first animals listed under Endangered Species Act, said Somer. It was upgred to threatened status in 1975. Threats to Paiute cutthroat trout included overfishing, disease, interbreeding and competition with n-native trout. 
species was invertently saved in early 1900s when sheepherders in area transported some of fish into a previously fishless portion of Silver King Creek above Llewellyn Falls. falls prevented n-native fish from reaching that stretch of water and kept Paiute isolated and genetic pool pure.

Restoration of species to its historic habitat

Just as restoration efforts were ramping up below falls, California was hit with a drought in 2011 that lasted for six years.  “ drought was a setback. Without sw cover in winter at elevation, stream literally freezes solid from bottom up,” Somer said. “It’s a major problem for trout throughout West.” From 2013 to 2015, 11 miles (18 kilometres) of Silver King Creek and three tributaries were treated with a fish toxicant, rotene, to remove all n-native species. That was first step of five-part recovery plan that could get Paiute off threatened species list within next dece or so, Somer said. Step two is Wednesday’s restoration of species to its historic habitat.

“ biggest hurdles are one and two,” he said. “That’s why this is definitely an event.” re will be ar transport by mule from Coyote Valley next year to ensure Silver King population hits about 2,500 and is self-sustaining, Somer said. About 100 miles (161 kilometres) rth in neighbouring Neva, officials are making fish-friendly modifications to a dam that for more than a century blocked off spawning grounds for Lahontan cutthroat trout, a threatened relative of Paiute cutthroat. Groundbreaking happened this month for a $23.5 million fish-pass project to help Lahontan cutthroat navigate Truckee River’s Derby Dam east of Re.
