The Snow Water Supply Forecasting Program Reauthorization Act of 2025 aims to enhance the Snow Water Supply Forecasting Program by emphasizing the integration of technologies for snowpack measurement and modeling. The bill extends funding for the program for fiscal years 2027 through 2031, allocating $6.5 million annually. It also expands the scope of technologies to include imaging spectroscopy, machine learning, and integrated snowpack and hydrologic modeling. The focus is on improving snow and water supply forecasting to address changing weather and watershed conditions, as well as building the capacity of program partners to implement and adapt to new capabilities.
