The Greater Yellowstone Network includes Bighorn Canyon National Recreation Area (NRA), Grand Teton National Park and John D. Rockefeller Memorial Parkway, and Yellowstone National Park (NP). In 2005, the Greater Yellowstone Network began monitoring water bodies identified by the states of Montana and Wyoming as "water quality impaired." By 2009, monitoring activities included water quality of impaired waters in Bighorn Canyon NRA and Yellowstone NP, outstanding natural resource waters in Grand Teton NP and Yellowstone NP, high alpine lakes in Grand Teton NP, and arid seeps and springs in Bighorn Canyon NRA.
