Basin Studies

Basin Studies addresses basin-wide efforts to evaluate and address the impacts of climate change. Funding is available for comprehensive water studies that define options for meeting future water demands in river basins in the western United States where imbalances in water supply and demand exist or are projected. Each study includes four key segments:

  • 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 options to improve operations and infrastructure to supply adequate water in the future.
  • Recommendations on how to optimize operations and infrastructure in a basin to supply adequate water in the future.
