Owyhee Reservoir is a 53-mile-long lake, filling a narrow, deep canyon brimming with colorful volcanic rock formations.  Many boaters return each year to explore the desert canyon and rugged mountains. Some of the geology is visible only by boat. Anglers are awarded excellent warm water catches, especially large mouth bass, white and black crappie.  The reservoir also has catfish and is occasionally stocked with rainbow trout.
