Navajo Lake is a small lake in northwestern Kane County in southern Utah. It is shallow, reaching depths of only 25 feet. Recreation includes fishing, boating, swimming, and lodging facilities. Species of trout in Navajo Lake are brook trout, splake trout (hybrid), and rainbow trout. Trout survival for winter is very poor with only the splake and brook trout overwintering. There is also a dense population of Utah chub. The lake was formed by a lava flow across the eastern end of the valley.
