Florida Gov. Rick Scott says the state is going to sue the state of Georgia over its increased consumption of water that is limiting flow to the Apalachicola River.
Scott in a statement said Florida needed to take the drastic action because it has been unable to negotiate a settlement for the last decades on how to allocate water between Florida, Georgia and Alabama.
Florida's step is an escalation in years of litigation.
Florida has previously sued the Army Corps of Engineers, which manages the Apalachicola-Chattahoochee-Flint river system. But a recent ruling went against Florida in its push to limit Georgia's withdrawals.
Florida's oyster industry has neared collapse in the last two years because of reduced water flow from the Apalachicola into the Gulf of Mexico and because of drought.
