“They never should have gone in the first place,” said Fred Crosby, 66, owner of Crosby Lodge, the only bar, restaurant, gas station and tackle shop in tiny Sutcliffe, Nev., a poor reservation town on the west shore of Pyramid Lake.

In the mid-1970s, the Paiute Tribe opened a fish hatchery in Sutcliffe and stocked Pyramid Lake with strains of Lahontan cutthroat from nearby lakes. The water in Pyramid Lake is saltier than Lake Tahoe, and that kept out the lake trout. The tribe re-established a Lahontan cutthroat sport fishery and saved Pyramid Lake’s endangered Cui-ui sucker from extinction. Anglers bought tribal licenses, hauled ladders out into the lake’s bracing water and considered any catch that weighed 10 pounds or more a trophy.

In the late 1970s, a fish biologist identified what he thought were surviving specimens of the vanished Pyramid Lake strain of Lahontan cutthroat in a small creek near a 10,000-foot mountain on the border of Nevada and Utah called Pilot Peak. A Utah man used buckets to stock the rugged stream with trout in the early 1900s, but made no record, federal biologists say. Geneticists recently compared cutthroats from the Pilot Peak stream with mounts of giant Pyramid Lake trout and discovered an exact DNA match.

“They are the originals,” said Corene Jones, 39, the broodstock coordinator for the Lahontan National Fish Hatchery in Gardnerville, Nev.

In 1995, United States Fish and Wildlife Service biologists harvested cutthroat eggs from Pilot Peak and brought them to the Gardnerville hatchery, just a few years before a devastating wildfire scorched the mountain and killed off the creek. In 2006 federal officials, in cooperation with the tribe, began stocking Pyramid Lake with what many now call Pilot Peak cutthroats. They waited to see how the fish might readapt to its ancestral home.

The answer came from ecstatic anglers. Late last year, a Reno man caught and released a 24-pounder. David Hamel, 27, of Reno, just did the same with a pair of 20-pound cutthroats.
