Bill: H.R.4832 | Sponsor: Rep. Lee, Susie (D-NV)
Policy area: Water Resources Development

Summary:
Open Access Evapotranspiration Data Act
This bill directs the U.S. Geological Survey (USGS) to establish an Open Access Evapotranspiration (OpenET) Data Program under which the USGS shall provide for delivering satellite-based evapotranspiration data to advance the quantification of evaporation and consumptive water use. The bill defines Evapotranspiration as the process by which water is transferred from the land to the atmosphere by evaporation from soil and other surfaces and transpiration from plants.
As part of the program, the USGS shall

To establish the Open Access Evapotranspiration (OpenET) Data Program.

    Be it enacted by the Senate and House of Representatives of the 
United States of America in Congress assembled,

SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Open Access Evapotranspiration Data 
Act''.

SEC. 2. DEFINITIONS.

    In this Act:
            (1) Evapotranspiration.--The term ``evapotranspiration'' 
        means the process by which water is transferred from the land 
        to the atmosphere by--
                    (A) evaporation from soil and other surfaces; and
                    (B) transpiration from plants.
            (2) Program.--The term ``program'' means the Open Access 
        Evapotranspiration (OpenET) Data Program established under 
        section 4(a).
            (3) Program partner.--The term ``program partner'' means--
                    (A) an institution of higher education;
                    (B) a State (including a State agency);
                    (C) a private sector entity;
                    (D) a nongovernmental organization; or
                    (E) any other entity determined to be appropriate 
                by the Secretary.
            (4) Secretary.--The term ``Secretary'' means the Secretary 
        of the Interior, acting through the Director of the United 
        States Geological Survey.

SEC. 3. FINDINGS.

    Congress finds that--
            (1) evapotranspiration is the second largest component of 
        the water budget, which is an accounting of the allocation of 
        water resources to various water uses;
            (2) evapotranspiration is a measure of the water that is 
        consumed and lost from a water system, removed from available 
        supplies, and unavailable for other uses within a watershed;
            (3) accurate information on evapotranspiration is required 
        to balance water supply and water demand in a watershed and 
        ensure that adequate water supplies for beneficial uses are 
        available over time;
            (4) water users and managers are impeded in more efficient 
        decisionmaking by--
                    (A) the lack of consistent and comprehensive water 
                use data; and
                    (B) the fact that access to existing data is often 
                limited and cost-prohibitive; and
            (5) evapotranspiration data may be applied for the purposes 
        of--
                    (A) assisting users and decisionmakers to better 
                manage resources and protect financial viability of 
                farm operations during drought;
                    (B) developing more accurate water budgets and 
                innovative management programs to better promote 
                conservation and sustainability efforts; and
                    (C) employing greater groundwater management 
                practices and understanding impacts of consumptive 
                water use.

SEC. 4. OPEN ACCESS EVAPOTRANSPIRATION (OPENET) DATA PROGRAM.

    (a) Establishment.--The Secretary shall establish an Open Access 
Evapotranspiration (OpenET) Data Program under which the Secretary

            (1) to advance the quantification of evaporation and 
        consumptive water use; and
            (2) to provide data users with field-scale estimates of 
        evapotranspiration data across large landscapes over certain 
        periods of time.
    (b) Purpose.--The purpose of the program is to support the 
operational distribution of satellite-based evapotranspiration data

        accounting, and water use reporting;
            (2) shall coordinate data analyses, use, and collection 
        efforts with other Federal agencies, States, and Tribal 
        governments through existing coordinating organizations, such
