Dolores River Basin

The Dolores River Basin stretches from western Colorado to New Mexico and has many wildlands, such as the treasured San Juan Mountains.

The Wilderness Society is working to protect more than 60,000 acres of wild mountains and rivers and to keep energy development out of the wildest places in the area. 

Why the Dolores River Basin

The Dolores River Basin and the San Juan Mountains are some of the wildest places in the Rocky Mountain region. It has stunning scenery, important wildlife habitat and some of the best recreation in the west. 

Work we’re doing

We work to make sure that the wild parts of the Dolores River Basin stay wild. 


Protecting the Dolores River Basin isn’t something we can do alone. We work with a coalition of local groups and communities to protect this slice of the Rocky Mountains.

The status quo of the program has impacted public lands to the tune of billions of dollars and could multiply if coal companies aren’t held responsible for cleanup as they go bankrupt. Damages due to climate change from mining emissions will cost billions and drinking water for entire cities could be lost to mining or polluted beyond safe drinking levels.
