      • (2) Focus
        • The program shall focus on activities that will maintain, establish, expand, or advance snowpack measurement and integrated modeling, with an emphasis on—
        • Focus
          • enhancing activities to achieve improved snow and water supply forecasting results that are more responsive to changing weather and watershed conditions;
          • activities in river basins where activities described in this section relating to snowpack measurement and water supply forecasting can inform water management decisions or models at a multi-water user, multi-basin, or multi-State scale, including interstate water management decisions; and
          • building the capacity of program partners to implement and adapt to the new measurement and forecasting capabilities enabled under the program.
    • by striking paragraph (2) and inserting the following:
  • in subsection (f)—
    • in the matter preceding paragraph (1), by striking and inserting ;
    • in paragraph (2), by striking ;
