BILLINGS, Mont. AP – A U.S. Supreme Court appointee has rejected Wyoming’s bid to dismiss a lawsuit in which it is accused, by Montana, of taking too much water from rivers shared by the two states.

Montana filed its lawsuit before the nation’s highest court in 2007. The suit alleged Wyoming’s agriculture and energy industries were pulling too much water from the Tongue and Powder rivers, tributaries of the Yellowstone. The case is before Special Master Barton Thompson, a Stanford University water-law expert appointed by the court.
