In 1904 Stewart Edward White communicated to his friend President Theodore Roosevelt, that overfishing could lead to extinction of the golden trout. In White's novel "The Mountains", he wrote about the threatened golden trout on California's Kern Plateau. Roosevelt shared White's concern and, through U.S. Fish Commissioner George M. Bowers, dispatched biologist Barton Warren Evermann of the U.S. Bureau of Fisheries to study the situation. In 1906 Evermann published "The Golden Trout of the Southern High Sierras". Based on morphology, Evermann accurately described four forms of this native fish: "Salmo roosevelti" from Golden Trout (Volcano) Creek, "Salmo aguabonita" from nearby South Fork of the Kern River, "Salmo whitei" (named in recognition of Stewart Edward White) from the Little Kern River, and "Salmo gilberti", the Kern River rainbow.
