Title 42 › CHAPTER 109B — SECURE WATER › § 10367
The Secretary must run a national streamgage program that measures streamflow and related weather and water data in important watersheds. The work must be steady and reliable so people and agencies can make water-management decisions. The program must collect extra data during floods and droughts, keep long-term records to spot changes and check links to global climate change, and work with Federal and State agencies (including the National Integrated Drought Information System) to improve water-availability knowledge, flood-hazard assessments, find data gaps, and better forecasts. The Secretary must use adaptive reviews, improve how data are analyzed and shared, and develop cheaper ways to measure streamflow. Within 10 years after March 30, 2023 (by March 30, 2033), the program must fund at least 4,700 streamgages, all made flood-hardened and fitted with precipitation and water-quality sensors and modern telemetry, and sites must meet Federal needs described in official feedback. The Federal government will pay 100% of the cost of that streamgage network. Money is authorized as needed for fiscal years 2009–2028, and $10,000,000 per year for the network upgrades is authorized for fiscal years 2009–2028. The Secretary must also build a nationwide groundwater monitoring program for each major aquifer. The program must set quality standards for monitoring wells (including real-time instruments when possible), check the status of wells that existed on March 30, 2009, and make plans to cover each major aquifer in coordination with the Advisory Committee, States, local agencies, and Tribes. Before starting new monitoring in a State or Tribal land after March 30, 2009, the Secretary must consult them and follow applicable laws. The goals are to improve knowledge of how surface water and groundwater interact, study climate effects on groundwater by covering each climate division, and support assessments. The Secretary must improve methods to measure recharge, discharge, and storage and may pay up to 100% of costs, while giving priority where States, Tribes, or local governments provide a large share of costs. Up to $4,000,000 per year is authorized for this work for fiscal years 2023–2028. The Secretary may also give nonrepayable grants to federal agencies, research institutes, universities, and private groups to develop better and cheaper water measurement and data methods. Priority research includes streamflow prediction and measurement, groundwater storage change, data standards and GIS validation, precipitation and evapotranspiration measurement, and tracking water withdrawals and use. Partnerships, including public-private ones, are encouraged. Up to $5,000,000 per year is authorized for these grants for fiscal years 2009–2028.
