Summary

Amends the Snow Water Supply Forecasting Program to focus on integrated snowpack measurement and modeling, names specific prioritized technologies (airborne laser altimetry, imaging spectroscopy, integrated physics‑based modeling, and other Secretary‑approved technologies), and clarifies program focus areas. Authorizes $3,000,000 per year for fiscal years 2027–2031 to carry out the revised program activities.

Key Points

• Revises the Snow Water Supply Forecasting Program to emphasize integrated snowpack measurement and modeling.
• Specifies prioritized technologies: airborne laser altimetry, imaging spectroscopy, integrated physics‑based modeling, and Secretary‑approved technologies.
• Adds a clear program "Focus" statement to guide activities toward measurement, modeling, and operational forecast improvements.
• Authorizes $3,000,000 annually for fiscal years 2027–2031 to support program activities.
• Authorization updates statutory language and funding levels but does not itself appropriate funds.
• Program changes are aimed at improving streamflow and water‑supply forecasting for water managers and related stakeholders.
• Encourages use of modern remote sensing and integrated modeling approaches, including demonstration and validation work.
• Does not create new mandates for states or local governments; it clarifies federal program priorities and permitted activities.
