This bill reauthorizes the existing Snow Water Supply Forecasting Program, updating its focus to emphasize the development and deployment of technologies that integrate snowpack measuring and modeling . It expands the list of specific technologies to be utilized, now including imaging spectroscopy , machine learning , and integrated snowpack and hydrologic modeling , to enhance data collection and analysis. The legislation also removes a previous reporting requirement and encourages collaboration with agencies like the Department of Agriculture and the National Oceanic and Atmospheric Administration. The reauthorized program will concentrate on activities that improve snow and water supply forecasting results, making them more responsive to evolving weather and watershed conditions. It prioritizes efforts in river basins where forecasting can inform multi-water user, multi-basin, or multi-State water management decisions , including interstate agreements. Furthermore, the bill mandates building the capacity of program partners to implement and adapt to these new measurement and forecasting capabilities. Finally, it reauthorizes appropriations for the program at $6,500,000 annually for fiscal years 2027 through 2031.
