CASPER, Wyo. (AP) — A Wyoming judge has signed a decree to end 37 years of water-rights cases in the Big Horn River basin and set how much water is to be allocated to federal, tribal and state interests.

The decree signed by Judge Robert E. Skar on Friday finalizes all of the interim orders that have been entered over the years, starting with a complaint filed in 1977 on the division of water rights in northern Wyoming.
