    Reliable water sources are central to human and environmental health. In south Texas, USA, the Nueces River Basin (NRB) directly or indirectly plays that important role for many counties. Several NRB stream segments are designated as ecologically significant because they serve crucial hydrologic, ecologic, and biologic functions. The hydrologically significant streams recharge the Edwards Author: E. Dave Thomas, Kartik Venkataraman, Victoria Chraibi, Narayanan Kannan. Rebich, Richard A., Natalie A. Houston, Scott V.
