However, in 1979 a remnant population of the original Pyramid Lake cutthroat trout was discovered in a small brook on Pilot Peak, on the Nevada/Utah border, by Dr. Robert Behnke of Colorado State University while he was looking for the Bonneville cutthroat trout, another subspecies of the cutthroat trout.

To the east of the range lie Pilot Valley Playa and its springs; beyond that the Silver Island Mountains, and the north section of Pilot Creek Valley to the west. Several fresh and salty springs flow from the base of the alluvial fans at the base of the range. The largest is Bettridge Creek, a habitat for the threatened Lahontan cutthroat trout ...
Springs are located in the alluvial fans at the base of the Pilot Range, and no water flows from the Silver Island Mountains. [citation needed] Shallow groundwater (e.g., Bettridge Creek, with threatened Lahotan cutthroat trout) along the western edge of the playa varies from fresh water to brine over a distance of about 2,000 feet.

This subspecies of cutthroat trout survives today in tributary rivers of the Great Basin, and has been reintroduced to Pyramid Lake and Walker Lake after being extirpated during the 20th century.
