My people have always been warriors.  We have always struggled against the US Government and with companies exploiting our lands.  Unfortunately, that fight is ongoing.  But where we once fought with bows and arrows now we fight in the courtroom.  Stand with us.

Nicole Ducheneaux, Lead Attorney and Member,

Cheyenne River Sioux Tribe


Many people believe that the battle against the Dakota Access Pipeline is over and that the oil companies won.  Nothing could be further from the truth.  In fact, the court case is very much alive and the Tribes are winning. 

Although construction has been completed and oil is now flowing under our sacred and vital water, the Tribes won two crucial court victories in 2017.

The fight is not over and there is so much left to do in the Dakota Access Pipeline lawsuit.  We are working with experts – biologists, hydrologists, ethnobotanists, eco-toxicologists, and others – to develop proof that the pipeline is unsafe.  We have been fighting since August 2016 and we may not be done for years.

The Cheyenne River Sioux Tribe is doing everything it can to protect the waters and the lands that sustain us all.  But we don’t have the same endless resources that fund Big Oil and the deep bench of litigators behind the U.S. government.

This fight is so critical to us that we are here today asking for you to stand with us.  This fight is ongoing.  We don’t get second chances on this kind of stuff.  We have to do it now. 

We can only fight as long as have the resources.  Join us!

The Dakota Access Pipeline is not the only battle we are fighting.  The Tribe’s battle against the Keystone XL Pipeline, a huge Alberta tar sands pipeline, has been going on for years.  We thought it died in 2014, but Donald Trump resurrected it in 2017.  Energy companies think that now that our lands and resources are theirs for the taking under this new administration.  They are wrong. 

​Today, the Keystone XL Pipeline is again knocking at our door.  This is a pipeline that has the potential to be even more disastrous for, not only the people of the Cheyenne River Sioux Tribe, but for all Americans.  The pipeline is proposed to cross just three miles from our Reservation border, under a waterway that feeds our drinking source, and through the sacred last camp of our Chief Bigfoot before the U.S. Army massacred him at Wounded Knee in 1890. 

​Keystone XL also has the potential to pollute the great Ogalalla Aquifer, the most important source of drinking water and agricultural water for Americans from North Dakota to Texas.

​Promises that this pipeline won’t leak are betrayed by the ongoing problems with the existing Keystone Pipeline.  Oil companies like TransCanada and Energy Transfer Partners get rich off our lands, with so little oversight and regulation from the U.S. government.



People who haven’t experienced life on our lands can’t imagine how deeply these pipelines and oil companies affect us and our way of life.  There are people in government who are making decisions on our behalf that don’t have a clue what we are losing. 

Harold Frazier, Chairman of the Cheyenne River Sioux Tribe
