The river has several tributaries, including the Peace River and the Kissimmee River, and is regulated by several dams, including the Franklin Lock and Dam. Seasonal trends show higher flows during wetter months and lower flows during drier months. The hydrology of the river is interesting because it has been heavily altered by human activity, including dredging and water management practices, which have impacted water quality and ecology. The river is also home to several endangered species, including the Florida manatee.
