WaterSMART Basin Studies

Basin Studies are collaborative studies, cost-shared with non-Federal partners, to evaluate water supply and demand and help ensure reliable water supplies by identifying strategies to address imbalances in water supply and demand. Each study includes four key elements:

  • State-of-the-art projections of future supply and demand by river basin.
  • An analysis of how the basin’s existing water and power operations and infrastructure will perform in the face of changing water realities.
  • Development of strategies to meet current and future water demands.
  • A trade-off analysis of strategies identified.



For more information regarding the Basin Study Program, please contact Avra Morgan at 303-445-2906.
