WASHINGTON — The U.S. Senate gave final passage Saturday to a water projects bill that includes a historic water rights settlement among Oklahoma City, the state of Oklahoma and the Choctaw and Chickasaw nations.

The bill, approved 78-21, now goes to the White House. President Barack Obama is expected to sign it.

Sen. Jim Inhofe, R-Tulsa, who put the Oklahoma settlement on the fast track by inserting it into the water projects bill he had been working on for two years, said Saturday, "I am proud of the bipartisan efforts that got this bill across the finish line and I look forward to seeing the benefits to Oklahoma in action.”

The water rights settlement was announced in August by the state of Oklahoma, Oklahoma City, and the Chickasaw and Choctaw Nations. It is expected to double the city's future water supply by granting an average of 110,000 acre feet per year of water from the Sardis Lake reservoir in southeastern Oklahoma.
