Water Monitoring and Tracking Essential Resources (WATER) Data Improvement Act

This bill reauthorizes and updates the U.S. Geological Survey's water monitoring program as the Federal Priority Streamgage Program, extending funding through 2028 at $4 million annually. It updates previous program descriptions to replace "national streamflow information program" with the new program name and requires regular stakeholder feedback to determine priorities. The bill specifically includes Tribes in program collaboration by adding provisions for "Tribal lands" and "Tribe" in program descriptions. It modifies reporting requirements to reference a 2022 USGS report on program priorities rather than a 2004 National Research Council review.
