The Caddo River is fed by several small tributaries, including the Little Missouri River and the Ouachita River. The river is also impounded by several dams, including DeGray Lake and Lake Ouachita. During the summer months, the river experiences low flows due to decreased precipitation, while the winter months bring increased flows due to rain and snowmelt. Interesting facts about the hydrology of the Caddo River include its role as a popular recreational destination for kayaking and fishing, as well as its significance as a habitat for endangered species such as the Ouachita Mountain shiner.
