Rivers and riverine ecosystems are under great stress in the western United States.  River managers face increased demand for reliable water supplies of high quality while also needing to maintain habitat for threatened and endangered native aquatic and riparian species. 

The mission of the Intermountain Center for River Restoration and Rehabilitation (ICRRR) is to advance the science and practice of river restoration and environmental management and to transfer that knowledge to the public and private sectors. ICRRR conducts its work through completion of targeted research projects, providing decision support to federal agencies and adaptive management programs, evaluating the performance of previously constructed restoration projects, and teaching short courses about stream restoration methodology to practitioners. 

ICRRR's regional focus is the streams and rivers of the Intermountain West. These riverine systems are critical ecosystem resources that support valued native and sport fisheries, while also supporting water supply and power production uses by society. Our goal is to promote the scientific management, rehabilitation, and restoration of these valuable ecosystems.

The success of ICRRR is measurable by the geographic range of its projects, the number of projects and the agencies with whom it collaborates, and the success of its short courses.  ICRRR has played a significant role in the development of an emerging bi-national program to rehabilitate the Rio Grande in the Big Bend region of Texas and Mexico; manage and rehabilitate riverine resources of the Colorado River system, including in Grand Canyon National Park and Dinosaur National Monument; and, management of the Snake River in Grand Teton National Park and Hells Canyon National Recreation Area.
