Snow Water Supply Forecasting Reauthorization Act of 2025

Sponsored by Jeff HurdRep. Jeff Hurd (R-CO)
Introduced June 10, 2025

AI-Generated Summary

Updated September 23, 2026 at 4:52 AM UTC

The Snow Water Supply Forecasting Reauthorization Act updates the existing program to focus on integrated snowpack measurement and water‑supply forecasting. It adds new high‑tech tools, expands the program’s role in real‑time forecasts and interstate water‑management decisions, and sets a five‑year funding level of $3 million per year.

Key Provisions

  • Directs the program to use integrated technologies such as airborne laser altimetry, imaging spectroscopy, physics‑based snowpack and hydrologic modeling, and machine‑learning methods.
  • Shifts the program’s focus to improving water‑supply forecasts, linking snow data to real‑time forecasts, and supporting river basins and interstate water‑management decisions.
  • Requires partners to build capacity to adopt and adapt to the new measurement and forecasting tools.
  • Adds reporting requirements that list basins using the technologies, assess which tools best inform forecasts, and compare new forecasts to existing benchmarks.
  • Sets annual funding at $3 million for fiscal years 2027 through 2031, replacing the previous aggregate $15 million allocation for 2022‑2026.
