The river is primarily fed by precipitation, but alongside that, it receives inflow from several tributaries, including the Saluda and Broad rivers. The Lake Murray Dam also affects the flow of the river. During the summer, the river experiences a decrease in water level due to low rainfall. However, in the winter, the river's flow can increase due to higher precipitation. Interestingly, the Congaree River has a unique ecosystem within Congaree National Park, serving as a habitat for several endangered species. This stream gauge is essential in tracking the water levels of the Congaree River and helping ensure its sustainability.
