Bonneville Cutthroat Species Distribution

The Bonneville Cutthroat Trout was historically found in the Bonneville Basin, including suitable habitat within the basin portions of Utah, Idaho, Wyoming and Nevada. Although scientists believed that pure strains of Bonneville Cutthroat were extinct 30 years ago, small populations have been found in nearly 70,000 acres of lakes and 850 miles of streams. The Bonneville Cutthroat's coloration is less vivid than other cutthroat species, and it has large, evenly distributed spots.
