Water districts located in North Texas are awaiting a U.S. Supreme Court decision that could be announced on June 11, 2013.  At issue is whether the Tarrant Regional Water District based in Fort Worth can cross the Oklahoma border to pump water available to Texas under the Red River Compact.  The Compact says that when the water in the Red River and its tributaries exceeds a certain level, each of four states- Texas, Oklahoma, Arkansas and Louisiana- is entitled to one fourth of the surplus. In April, the Tarrant district told Supreme Court justices Texas can’t get its fair share without pumping it from the Oklahoma side of the border.  Read More About the U.S. Supreme Court Water Decision.
