…sustaining our natural water systems


The Park's unique geothermal and hydrological features are one of the main reasons why Yellowstone became the world's first National Park. In addition Yellowstone is at the headwaters of the Yellowstone River itself an important natural resource contributing to major waterways like the Columbia and Missouri Rivers. Climate change is expected to cause drier conditions in the Rocky Mountain West. With a changing and drier climate it is critical that we conserve water and ensure that our facilities and operations have minimal impact on water resources. Yellowstone is working to reduce its use of potable water by inspiring behaviors to conserve water and using water smart technology, and integrating design changes that minimize impacts of park structures on natural water systems.
