Tribes join lawsuit intervention.

(Montana) The Confederated Salish and Kootenai Tribes joined six other tribes in defense of a new federal rule protecting their water rights in court.

The rule requires states to consider tribes’ fishing, hunting and gathering rights while crafting water regulations.

Twelve states sued the U.S. Environmental Protection Agency over the rule, which was finalized earlier this year.

Seven tribes have filed a motion to intervene in the case. They say the rule is key to protecting “reserved rights,” which gives tribes the ability to hunt, fish and gather on lands they ceded to the federal government through treaties.
