WASHINGTON (AP) — The Supreme Court says Nebraska should pay $3.7 million in damages to Kansas in a long-running legal dispute over use of water from the Republican River.

The justices on Tuesday also agreed with the recommendations of a special master who found that Nebraska should pay $1.8 million on top of actual damages for using more than its legal share of the river’s water in 2005 and 2006.

The dispute centers on a 1943 compact allocating 49 percent of the river’s water to Nebraska, 40 percent to Kansas and 11 percent to Colorado.

Since 1999, Kansas has complained that Nebraska uses more than its fair share of water from the river, which originates in Colorado and runs mostly through Nebraska before ending in Kansas.
