Loxahatchee River is about an 8 mile long river north of West Palm Beach in Florida. It is Florida’s first National Wild and Scenic River receiving the federal designation in 1985. A National Wild and Scenic River is designation for protected areas in the United States.
One thing I can say for Florida - they value their waterways and it attracts a lot of tourists including kayakers and canoeists. Alabama values their waterways as trash chutes which is why kayak tourism is about dead in Alabama.
