A cutthroat trout population in Pine Creek, White Pine County, Nevada, which historically has been thought of as a remnant population of the Bonneville Cutthroat trout, (Salmo clarki utah), is in all probability a new undescribed subspecies of cutthroat trout. Besides an unusual morphology, the Pine Creek trout have fewer scales, more gillrakers, many more basibrachial teeth and a more uniform distribution of spots on the body. Subsequent investigations of other streams with Bonneville Basin drainage have revealed cutthroat trout populations with similar distinctive traits and that the Pine Creek form of trout was once the native trout of the whole Snake Valley and probably co-existed in Lake Bonneville with s. c. utah. Cutthroat trout populations of Pigs Creek stock have been started in several previously barren streams in order to insure the subspecies survival. Stream improvement and land protective measures have been initiated to insure success of these transplants.
