11. Difficult to Compare Water Use by Sector across state lines due to different methods and data sets

12. Future Needs Consumptive Use vs. Diversions Improved groundwater information Increased use of remote sensing to determine water use More consistency between states on how water use data are collected/available Support Sec. 9508 of SECURE Water Act (P.L. 111-11) for state/federal partnership in water use data Improved long-term supply forecasting
