See Appendix A for methodology. Ranked by anomaly. Chart includes only the power plants that require water for cooling, or whose cooling needs were unspecified. Sub-basin name is the name of the eight-digit Hydrologic Unit Code (HUC-8) used by the U.S Geological Survey. plant fuel type and reported plant cooling type include multiple entries for plants reporting more than one fuel or cooling type. anomaly is the difference between the calculated with and without power plant water use included. The is calculated using USGS water demand data in combination with our calculations of power plant water use based on reported generation for 2008, the median NREL coefficients (Macknick et al. 2011), and reported water source.
