Official Summary

Snow Water Supply Forecasting Reauthorization Act of 2025 This bill reauthorizes through FY2031 and modifies the Snow Water Supply Forecasting Program of the Bureau of Reclamation. Under the existing program, Reclamation implements activities to improve snowpack measurements used for water supply forecasts in certain western states. The bill directs Reclamation to incorporate, to the greatest extent practicable, information from technologies that provide complete integration of accurate, timely, and spatially complete snowpack measurements and models when determining water supply forecasts or allocations to federal water contractors. Additionally, the bill requires the program's framework to emphasize the deployment of technologies that provide integration of snowpack measuring and modeling. The bill also requires the program's focus—activities that maintain, establish, expand, or advance snowpack measurement and integrated modeling—to place an emphasis on (1) enhancing activities to achieve improved snow and water supply forecasting results that are more responsive to changing weather and watershed conditions, (2) real-time integration of measurement and modeling activities with water supply forecasts, (3) activities in river basins where measurements or modeling can produce snow and water supply data to inform water management decisions, and (4) building the capacity of the program partners to implement and adapt to the new measurement and forecast capabilities.

Executive Summary

The Snow Water Supply Forecasting Reauthorization Act of 2025 reauthorizes and modifies the Snow Water Supply Forecasting Program managed by the Bureau of Reclamation through fiscal year 2031. The program focuses on improving snowpack measurements and integrating advanced technologies to enhance water supply forecasts in certain western U.S. states. The bill emphasizes the use of real-time data integration, improved modeling, and capacity building among program partners to better respond to changing weather and watershed conditions, thereby supporting water management decisions in river basins reliant on snowpack data.

Bottom Line

This bill extends and updates a federal program to improve snowpack measurement and water supply forecasting in western states, aiming to enhance water resource management through advanced technology integration and real-time data.
