SHERIDAN, Wyo. (AP) — Officials from the Wyoming Attorney General's Office are holding a conference call Monday with officials in Montana to discuss a solution to an ongoing conflict over water rights along the Tongue River.

The discussions were scheduled after the U.S. Supreme Court approved a recommendation by a special master finding Wyoming liable for taking Montana water in 2004 and 2006.

The two sides must agree how those issues will be resolved and how long it will take.

The amount of water involved is relatively small, but Montana wants guidelines that Wyoming must follow in the future when Montana calls for water to be released under provisions of the Yellowstone River Compact.

That agreement regulates the administration of water rights on rivers in the Yellowstone River tributary.
