US SB2437

Reauthorizes the Snow Water Supply Forecasting Program for fiscal years 2027 through 2031 at $6,500,000 per year, replacing the previous authorization of $15,000,000 aggregate for fiscal years 2022-2026

Expands authorized snowpack measurement technologies to include imaging spectroscopy, machine learning, and integrated snowpack and hydrologic modeling

Shifts program emphasis from pilot testing emerging technologies to development and deployment of technologies that integrate snowpack measuring and modeling for operational water supply forecasting

Prioritizes activities in river basins where improved forecasting can inform multi-water user, multi-basin, or multi-State water management decisions, including interstate water management

Requires annual reports listing basins using integrated modeling technologies and assessing which technologies best inform water supply forecasting for multiple water districts, communities, or States
