§10367 Water Data Enhancement by United States Geological Survey

Title 42 › Chapter 109B— SECURE WATER › § 10367

Last updated Apr 5, 2026|Official source

Summary

The Secretary must run a federal priority streamgage program that measures streamflow and related water conditions in major watersheds on a steady, continuous basis. The program must collect extra data during and after floods and droughts, keep a core network for tracking long-term streamflow changes and checking links to global climate change, work with other Federal and State agencies (including the National Integrated Drought Information System) to improve water-availability and flood-hazard information, fill data gaps, and improve forecasting. The Secretary must also keep improving methods and technology to measure streamflow more cheaply. Within 10 years after March 30, 2023, the national streamflow information program must fund not less than 4,700 streamgage sites, and all sites must be flood-hardened and fitted with precipitation and water-quality sensors and modern telemetry. The Federal share for that network is 100 percent. There are authorized appropriations for operation for fiscal years 2009 through 2028 (amounts as needed), and $10,000,000 per fiscal year for the network enhancements for fiscal years 2009 through 2028. The Secretary must also create a systematic groundwater monitoring program for every major U.S. aquifer. That program must set quality criteria for wells, include real-time instruments when possible, assess existing wells as of March 30, 2009, and work with advisory groups, States, local agencies, and Tribes. The Secretary must consult and follow State or Tribal law before starting monitoring in a State or on Tribal lands. The program must provide data on surface–groundwater connections, expand monitoring to each climate division to study climate effects on recharge and availability, and support assessments. The Secretary must improve methods and tech to measure recharge, discharge, and storage, may fund up to 100 percent of costs, and should give priority where States, Tribes, or local governments agree to pay a substantial share. Authorized funding is $4,000,000 per fiscal year for fiscal years 2023 through 2028. The Secretary may also award nonreimbursable grants to experts and institutions to develop new methods and improve data delivery, giving priority to projects on streamflow prediction, groundwater storage estimates, data standards and analysis, precipitation and evapotranspiration measurement, and water withdrawals and uses; partnerships are encouraged. Authorized grants funding is $5,000,000 per fiscal year for fiscal years 2009 through 2028.

(B)investigate, develop, and implement new methodologies and technologies to estimate or measure streamflow in a more cost-efficient manner.
(4)(A)Not later than 10 years after March 30, 2023, in accordance with subparagraph (B), the Secretary shall—
(i)increase the number of streamgages funded by the national streamflow information program to a quantity of not less than 4,700 sites; and

(b)(1)The Secretary shall develop a systematic groundwater monitoring program for each major aquifer system located in the United States.
(2)In developing the monitoring program described in paragraph (1), the Secretary shall—
(A)establish appropriate criteria for monitoring wells to ensure the acquisition of long-term, high-quality data sets, including, to the maximum extent possible, the inclusion of real-time instrumentation and reporting;
