The Tennessee Water Resources Research Center (TNWRRC) is a federally designated state research institute supported in part by the U.S. Geological Survey. It serves as a primary link among water-resource experts in academia, government, and the private sector, and the diversity of its staff in terms of background and expertise enhances flexibility and positions the Center to establish productive partnerships. TNWRRC is housed within the Institute for a Secure and Sustainable Environment (ISSE) at the University of Tennessee.
