Directs the Secretary to proceed with implementation of the national streamflow information program, as reviewed by the National Research Council in 2004.
Requires the Secretary to:
(1) measure streamflow and related environmental variables in nationally significant watersheds to develop a comprehensive source of information on which decisions relating to the management of water resources may be based;
(2) provide for a better understanding of hydrologic extremes through intensive data collection activities;
(3) establish a base network that provides resources necessary for the monitoring of long-term changes in streamflow and the conduct of assessments to determine the extent to which each long-term change is related to climate change;
(4) integrate the national streamflow information program with data collection activities of federal and state agencies to enhance the comprehensive understanding of water availability, improve flood-hazard assessments, identify any data gap regarding water resources, and improve hydrologic forecasting; and
(5) incorporate principles of adaptive management in the periodic reviews of information collected to assess whether program objectives are being adequately addressed.
Directs the Secretary to: (1) improve methodologies relating to the analysis and delivery of data; and (2) investigate, develop, and implement new methodologies and technologies to estimate or measure streamflow in a more cost-efficient manner.
Requires the Secretary, within 10 years, to:
(1) increase the number of streamgages funded by the program to not less than 4,700 sites; and
(2) ensure all streamgages are flood-hardened and equipped with water-quality sensors and modernized telemetry.
Requires each site to conform with the program plan as reviewed by the National Research Council. Sets the federal share of the of the cost of the national streamgaging network at 100%.
(1) necessary to operate the program for FY2009-FY2023; and
(2) to carry out network enhancements for each of FY2009-FY2019.
Directs the Secretary to develop a systematic groundwater monitoring program for each major aquifer system in the United States. Requires the Secretary:
(1) to establish appropriate criteria for monitoring wells to ensure the acquisition of long-term, high-quality data sets;
(2) in coordination with the Advisory Committee and state and local water resource agencies, to assess the current scope of groundwater monitoring based on the access availability and capability of each existing monitoring well and to develop and carry out a monitoring plan that maximizes coverage for each major U.S. aquifer system; and
(3) prior to initiating any specific monitoring activities within a state, to consult and coordinate with the appropriate state water resource agency with jurisdiction and to comply with applicable state laws.
Directs the Secretary to:
(1) provide data necessary for the improvement of understanding regarding surface water and groundwater interactions;
(2) support the groundwater climate response network to improve the understanding of the effects of climate change on groundwater recharge and availability by expanding the network of monitoring wells to reach each climate division; and
(3) support the objectives of the assessment program.
Sets the federal share of the cost of the monitoring program at 100%.
Directs the Secretary to give priority to those activities for which a state or local governmental entity agrees to provide for a substantial share of the cost of establishing or operating a monitoring well or other measuring device to carry out a monitoring activity.
Authorizes appropriations for FY2009-FY2023.
Directs the Secretary to conduct a study of available data to: (1) identify significant U.S. brackish groundwater resources and consolidate available data relating to each resource; and (2) report to the appropriate congressional committees. Authorizes appropriations for FY2009-FY2011.
Authorizes the Secretary to provide grants to entities with expertise in water resource data acquisition and reporting to:
(1) investigate, develop, and implement new methodologies and technologies to estimate or measure water resources data in a cost-efficient manner; and
(2) improve methodologies for the analysis and delivery of data.
Directs the Secretary to give priority to entities that propose the development of new methods and technologies for:
(1) predicting and measuring streamflows;
(2) estimating changes in the storage of groundwater;
(3) improving data standards and methods of analysis;
(4) measuring precipitation and potential evapotranspiration; and
(5) water withdrawals, return flows, and consumptive use.
Directs the Secretary to encourage partnerships among federal agencies, academic institutions, and private entities to promote objectives described in this paragraph.
Authorizes appropriations for FY2009-FY2019.
