Several big-name conservation organizations are seeking to give input to the U.S. Supreme Court battle between Florida and Georgia over water sharing in a basin the two states share. The National Audubon Society, Defenders of Wildlife, Florida Wildlife Federation and Apalachicola Riverkeeper are asking Ralph Lancaster, a Maine lawyer set to preside over an Oct. 31 trial between the two states, to allow them to file “friend of the court” briefs in the matter. “The court’s decision here will directly determine the fate of the Apalachicola River watershed and may well establish important precedent for future interstate water disputes that inevitably will arise in the face of growing human populations, a changing climate regime, and myriad federal and state legal mandates to protect ecosystem health,” the organizations stated in a court document filed Thursday.
