About The 

Cheyenne River Sioux Tribe

Our Lakota Nation is comprised of over three million acres of beautiful nature with three major waterways including the Missouri River, The Cheyenne River and The Moreau River located in central South Dakota.

The Cheyenne River Reservation is home to the four bands (Tiospaye) of the “Titunwan” People of the Plains: The “Mnicoujou” Planters By The Water, “Oohenumpa” Two Kettle, “Itazipco” Without Bows, and “Siha Sapa” Black Foot. 

The Keystone XL Pipeline is routed to come within 3 miles of our reservation.  TransCanada wants to put a "man camp" next to our reservation.  Our women, children and youth would be put at high risk from a group of mostly men.  This would make a volatile social situation which will cause harm to our people. 

We have been fighting against the Keystone XL Pipeline since 2015 and are continuing to fight against Big Oil. 

Keystone XL


On August 10, 2016, we intervened in the lawsuit against the US Army Corps of Engineers related to the easement at the Lake Oahe.  


Big Oil wants you to think we've lost, but we still have a chance to win.

Join us in the fight to protect our water, and the water for millions of people living downstream from the Missouri River.

Watch the Untold Stories of the

Water Protectors of Wakpa Wasté

The Water Protectors of Wakpa Wasté is produced by the Cheyenne River Sioux Tribe and directed by Salish filmmaker, Jessi Roullier.  The film tells the untold story of the Tribe at the forefront of the battle for the future of the planet.  The documentary was filmed on location in South Dakota on the Cheyenne River Sioux Reservation, known in Lakota as the Wakpa Wasté Oyanke (the Good River Reservation).


In spite of the hard life on the Cheyenne River Sioux Reservation and the Tribe’s meager resources, the Tribe and its members have committed their bodies and souls to protecting the lands and the waters that give us all life … because the Lakota people believe they were put on this Earth to protect it.

About the Film

“We Lakota people have been through some dark times in our history.  This pipeline fight is one those times, with Trump and Big Oil ganging up to desecrate our Grandmother Earth. But over the past year I have seen Indians and non-Indians join together like I’ve never seen before to protect our lands and waters. It gives me hope, because I believe that there are brave people out there who are willing to join us and sacrifice as we have to fight like hell for this planet.”

- Harold Frazier, Cheyenne River Sioux Tribal Chairman

The film features the unsung Lakota heroes who led the historic fight against Big Oil and corporate greed at Standing Rock and the modern warriors who are gearing up to continue this fight against the Keystone XL Pipeline. These are the voices and the faces of the true heart of Indian Country—voices who have never been heard on cable news and faces that have never been featured on a meme. They are the tribal leaders, the grassroots Lakota warriors, modern lawyer warriors, and the everyday Lakota people who have devoted their lives to ensuring a clean and healthy environment for future generations.

Unfortunately, as The Water Protectors of Wakpa Wasté depicts, the fight to protect the Earth is long, arduous, and expensive, and the Tribe can’t fight the fight alone. The film calls on the American people to stand up with the Tribe and join this fight, finance this fight, because if they don’t, they too will lose more and more of this Earth that sustains them.
