The Apache trout is one of only two trout native to Arizona. It has been designated as Arizona's state fish. The Apache trout was historically found only in the headwaters of the White, Black and Little Colorado rivers above 5,900 feet. Once nearing extinction, Apache trout have been restored to much of their historic range in the White Mountains after decades of cooperative protection and recovery efforts. Apache trout have an olive-yellow body, with a yellow or golden belly. They can grow up to 20 inches long, but most grow only to 9 inches because of the smaller streams in which they live.
