Muddy Ridge is an expanse of undeveloped land in the northeast portion of the Wind River Indian Reservation removed from Tribal control in 1920 to create irrigation infrastructure for non-Tribal residents. GYC is working in lockstep with Tribal leadership from both the Eastern Shoshone and Northern Arapaho Tribes to advocate for the repatriation of Muddy Ridge and resolve this decades-old injustice.

Rivers are the lifeblood of Montana. A low snow year, coupled with the impacts of population growth and climate change, are stark reminders that our rivers need our help. That’s why now is the time to pass the Montana Headwaters Legacy Act (MHLA). As we anticipate the bill’s hearing this spring, we critically need Senator Daines to support the MHLA.

The Montana Headwaters Legacy Act (MHLA) is back in U.S. Senate. We need you to help make it law.

If passed, House Bill 971 would repeal the Montana Environmental Policy Act (MEPA) for significant projects that could harm our environment and climate if the Montana Supreme Court were to ever find that Montanans’ right to a clean and healthful environment requires state agencies to consider climate impacts.

As a part of GYC’s Tribal work, we’re gathering people together to dive into impactful stories, photos, and film that showcase the social, economic, and cultural injustices against Indigenous People.
