S. 2437 — Snow Water Supply Forecasting Program Reauthorization Act of 2026

This section reauthorizes the Snow Water Supply Forecasting Program through FY2031 (from FY2026) at $3 million annually (from $15 million aggregate for FY2022–2026). It expands the program to incorporate water supply forecasting using technologies including imaging spectroscopy, machine learning, and snowpack and hydrologic modeling; requires coordination with the Department of Agriculture and the National Oceanic and Atmospheric Administration; removes the prior report requirement before implementation; and updates annual reporting to list basins using the technologies, assess which best inform multi-district forecasts, and compare new forecasts against benchmarks from those agencies.
