Water Research Optimization Act of 2025

A bill to modify operations of the National Water Center of the National Oceanic and Atmospheric Administration, and for other purposes.

Introduced April 30, 2025

AI-Generated Summary

Updated November 24, 2025 at 12:54 AM UTC

The Water Research Optimization Act of 2025 updates how the National Water Center within NOAA operates. It makes the NWC the central agency for federal water research and forecasting, linking it with other agencies and integrating advanced water‑modeling tools into the nation’s unified weather forecast system. The bill also gives the Under Secretary new oversight of river forecast centers and a key hydrology research institute.

Key Provisions

  • Makes the National Water Center (NWC) the lead agency for moving federal water research, including model development, into NOAA and National Weather Service (NWS) operations.
  • Designates the NWC as the primary NOAA hub for research, development, collaboration, and coordination of water‑related work with other federal agencies such as the USDA, Army Corps of Engineers, Bureau of Reclamation, USGS, and FEMA, and to promote consistent hydrologic forecasting nationwide.
  • Requires the Under Secretary to use the Weather and Climate Operational Supercomputing System (or its successor) to create advanced water‑resources models and to embed those models into the unified forecast system used for weather and climate predictions.
  • Gives the Under Secretary, through the NWS Office of Water Prediction, authority to supervise and coordinate the operations of each River Forecast Center with the NWC.
  • Assigns the Under Secretary responsibility for administering the Cooperative Institute for Research to Operations in Hydrology (or any successor) and coordinating its activities with the NWC.
  • Extends certain program authorizations to cover fiscal years 2024 through 2028 (and later language adds coverage through fiscal years 2026‑2030).
