The black river in Arizona has great trout fishing. The two forks of this river are home to one of Arizona's native trout—the Apache cutthroat. The upper sections of the East and West fork are considered to have the best trout fishing. The best access to the black river is via dirt forest roads. The best time to fish this river is mid-summer, because spring will bring a lot of runoff and late summer and fall might have very low water levels.
