To establish the Twenty-First Century Water Commission to study and develop recommendations for a comprehensive water strategy to address future water needs.

Summary: Establishes the Twenty-First Century Water Commission to: (1) use studies and assessments to project future water supply needs and demand, develop national and regional assessments on flood risk and water availability and trends related to water quality; (2) study government and private sector water management programs directed at increasing water supplies, managing flood risk, and improving the availability, reliability, and quality of water resources; and (3) develop recommendations for a comprehensive water strategy.

Requires such strategy to: (1) identify incentives to ensure an adequate and dependable supply of water to meet U.S. needs for the next 50 years; (2) consider all available technologies and methods to optimize water supply reliability, availability, and quality, while safeguarding and enhancing the environment; (3) suggest financing options for development of comprehensive watershed management plans, regional watershed planning, holistically designed water resources projects, and increased use of nonstructural elements (including green infrastructure and low impact development techniques); (4) encourage the integration of flood control and water supply projects, including recommendations for capturing excess water and flood water for conservation and reuse; (5) suggest options to promote the use of, and reduce biases against, nonstructural elements when managing stormwater; and (6) encourage the avoidance and minimization of adverse impacts to, and the restoration of, natural systems.

Directs the Commission, in developing such strategy, to: (1) evaluate the effectiveness of hazard mitigation strategies and contingency planning provisions for water management programs in light of climate change impacts; (2) evaluate such impacts; (3) include strategies for using best available climate science in projections of future flood and drought risk and for developing hazard mitigation strategies to protect water quality in extreme weather conditions caused by climate change; (4) identify adaptation techniques, or further research needs of such techniques, for responding to climate change impacts; (5) respect the primary role of states in adjudicating, administering, and regulating water rights and water uses; (6) identify whether recommendations are consistent with existing laws; (7) identify duplication among federal governmental programs and make recommendations to improve coordination among federal, interstate, state, and local agencies; and (8) avoid suggesting increased mandates on state and local governments.

 Requires the Commission to submit interim and final reports to the President and Congress. Terminates the Commission 30 days after its transmission of a final report. Authorizes appropriations.

SECTION 1. 21ST CENTURY WATER COMMISSION.

    (a) Establishment.--There is established a commission to be known 
as the 21st Century Water Commission (in this section referred to as 
the ``Commission'').
    (b) Duties.--The duties of the Commission shall be to--
            (1) use existing water studies and assessments and conduct 
        such additional studies and assessments as may be necessary, 
        including studies and assessments on climate change impacts, 
        to--
                    (A) project future water supply needs and demand;
                    (B) develop national and regional assessments on 
                flood risk and water availability; and
                    (C) develop national and regional trends related to 
                water quality;
            (2) study current water management programs of Federal, 
        interstate, State, and local agencies and private sector 
        entities directed at increasing water supplies, managing flood 
        risk, and improving the availability, reliability, and quality 
        of water resources; and
            (3) develop recommendations, in consultation with 
        representatives of such agencies and entities, for a 
        comprehensive water strategy that--
                    (A) identifies incentives to ensure an adequate and 
                dependable supply of water to meet the needs of the 
                United States for the next 50 years;
                    (B) considers all available technologies and other 
                methods to optimize water supply reliability, 
                availability, and quality, while safeguarding and 
                enhancing the environment;
                    (C) suggests financing options, incentives, and 
                opportunities for development of comprehensive 
                watershed management plans, regional watershed 
                planning, holistically designed water resources 
                projects, and increased use of nonstructural elements 
                (including green infrastructure and low impact 
                development techniques);
                    (D) encourages, to the maximum extent practicable, 
                the integration of flood control and water supply 
                projects, including recommendations for capturing 
                excess water and flood water for conservation and 
                reuse;
                    (E) suggests options to promote the use of, and 
                reduce biases against, nonstructural elements 
                (including green infrastructure and low impact 
                development techniques) when managing stormwater, 
                including features that--
                            (i) preserve and restore natural processes, 
                        landforms (such as floodplains), natural 
                        storage, natural vegetated stream side buffers, 
                        wetlands, or other topographical features;
                            (ii) utilize natural design techniques that 
                        infiltrate, filter, store, evaporate, and 
                        detain water close to its source; or
                            (iii) minimize the use of impervious 
                        surfaces;
                    (F) encourages the avoidance and minimization of 
                adverse impacts to natural systems, and where possible, 
                the restoration of natural systems; and
                    (G) addresses other objectives related to a 
                comprehensive water strategy which the Commission shall 
                consider appropriate.

        Commission shall--
                    (A) evaluate the effectiveness of existing hazard 
                mitigation strategies and contingency planning 
                provisions for Federal, interstate, State, and local 
                water management programs in light of climate change 
                impacts, including sea level rise, changing weather 
                patterns, increased risk of flooding or drought, and 
                associated impacts to water quality;
                    (B) consider and evaluate the impacts of climate 
                change;
                    (C) include strategies for using best available 
                climate science in projections of future flood and 
                drought risk, and for developing hazard mitigation 
                strategies to protect water quality in extreme weather 
                conditions caused by climate change; and
                    (D) identify adaptation techniques, or further 
                research needs of adaptation techniques, for responding 
                to climate change impacts.

                rights and water uses;
                    (B) identify whether recommendations are consistent 
                with existing laws, treaties, decrees, and interstate 
                compacts;
                    (C) identify duplication among Federal governmental 
                programs, and make recommendations to improve 
                coordination among Federal, interstate, State, and 
                local agencies; and
