Water resources are critical to the health and productivity of all landscapes, and especially the semi-arid and arid landscapes of the Greater Yellowstone Area. Water resources within Bighorn Canyon National Recreation Area and Grand Teton and Yellowstone national parks are also important to visitor recreational experiences and their perception of these natural places. These parks contain some of the most iconic water resources in the western U.S. The Yellowstone and Snake rivers are of considerable significance to the biological diversity and functioning of the Greater Yellowstone Ecosystem, but also to the health and vitality of nearby communities. Similarly, Bighorn Canyon National Recreation Area contains a complex of spring and seep habitats that are critical to the biodiversity of this semi-arid landscape and the aquatic and terrestrial organisms of the region.

In order to track changes in the status and trends of water resources, monitoring protocols specific to the resources of each park have been implemented. These monitoring protocols were designed to provide park- and resource-specific information that is needed to identify, quantify, and understand changes in key water resources. The information gathered from this monitoring will aid in determining whether observed conditions are relatively static, within the natural range of variation, or changing in ways that may be linked to key environmental drivers or anthropogenic influences.
