Samples were taken from fish in the Pilot Peak streams and were later used for DNA testing. On Pilot Peak, a remote and rugged mountain on the Utah-Nevada border, some biologists discovered what they thought were pure Pyramid Lake strain Lahontan cutthroat trout. Fish and Wildlife Service, in partnership with the Pyramid Lake Paiute Tribe, stocked the Pilot Peak strain back into its home waters in Pyramid Lake. In the early 1900s, before Fish and Wildlife Services existed, a wildlife commission took small fish from Pyramid Lake and Lake Tahoe and placed them in streams in eastern Nevada and across the border in Utah. The fish has returned to its natural migration and reproduction pattern from Pyramid to Tahoe. The Pilot Peak strain grew larger than the older terminal lake strains and fish well over 20 pounds are being angled in Pyramid Lake. These were transferred to Heenan during the mid-1940s. At the … Credit: Dan Hottle/USFWS, “Last year was the first time we observed the cutthroat moving out of the lake and spawning naturally in the lower reaches of river since the hatchery first began raising them from our brood stock in 1995 and stocking them in the lake with the help of the tribe in 2006,” said Lisa Heki, project leader for the hatchery complex. Today, anglers are catching trout up to 30 pounds. It was just happenstance that they got rediscovered.”. Credit: Dan Hottle/USFWS. "Pilot Peak" Lahontan Cutthroat Trout: The largest in it’s class, the Pilot Peak strain of cutthroat is the biggest that exist in the world today. Most of these Pilot Peak fish have had their adipose fins clipped at the hatchery, therefore it is very easy to distinguish them amongst the regular Pyramid (Summit) strain of cutthroat. Is it their bucket-shaped mouths that allow the biggest specimens to prey upon other fish that would be classified as trophies in other waters? The Nevada Department of Wildlife recently closed angling within 1,000 feet of Derby Dam, located about 30 miles upstream from the lake, just outside the Pyramid Lake Paiute tribal boundary. “To see these fish we’ve raised from eggs in the hatchery growing to massive sizes in the lake over the past few years and now watching them run up the river has been the most rewarding experience in fish conservation I’ve ever had,” said Roger Peka, a Lahontan National Fish Hatchery fish biologist. “This year they’re using the high water flows to run even further up into territory they haven’t been documented in since the late 1930s.”. The Smithsonian, Cal Academy and University of Michigan had specimens from the late 1800s through the early 1900s, but they were preserved in a way that made it very difficult to get the DNA out.
