Oklahoma officials declared victory when a federal judge dismissed part of a North Texas water district's lawsuit that claimed it had the right to buy billions of gallons of water from basins in southern Oklahoma. Not so fast. The Tarrant Regional Water District plans to amend the lawsuit and continue its legal fight in hopes of eventually negotiating a deal that would pay the state millions of dollars each year for water the district maintains Oklahomans do not need. "One basin in southeastern Oklahoma could provide the water needs of the entire state," said Hopper Smith, a former state representative who is now a lobbyist for the water district that serves Fort Worth, Texas, and surrounding communities. The district's general manager, Jim Oliver, said Oklahoma has more than 10 times the water it needs to meet its own needs and the district wants only about 6 percent of water flowing into the Red River that separates Oklahoma and Texas from Cache Creek, Beaver Creek and the Kiamichi River - water that eventually flows into the Gulf of Mexico.
