TEXAS WATER DEVELOPMENT BOARD; BOND ISSUE; TEXAS WATER DEVELOPMENT FUND.

(a) The Texas Water Development Board, an agency of the State of Texas, shall exercise such powers as necessary under this provision together with such other duties and restrictions as may be prescribed by law. The qualifications, compensation, and number of members of said Board shall be determined by law. They shall be appointed by the Governor with the advice and consent of the Senate in the manner and for such terms as may be prescribed by law.

(b) The Texas Water Development Board shall have the authority to provide for, issue and sell general obligation bonds of the State of Texas as authorized by constitutional amendment or by a debt proposition under Section 49 of this article. The bonds shall be called "Texas Water Development Bonds," shall be executed in such form, denominations and upon such terms as may be prescribed by law, and may be issued in such installments as the Board finds feasible and practical in accomplishing the purpose set forth herein.

(c) All moneys received from the sale of the bonds shall be deposited in a fund hereby created in the State Treasury to be known as the Texas Water Development Fund to be administered (without further appropriation) by the Texas Water Development Board in such manner as prescribed by law.

(d) Such fund shall be used only for the purpose of aiding or making funds available upon such terms and conditions as the Legislature may prescribe, to the various political subdivisions or bodies politic and corporate of the State of Texas including river authorities, conservation and reclamation districts and districts created or organized or authorized to be created or organized under Article XVI, Section 59 or Article III, Section 52, of this Constitution, interstate compact commissions to which the State of Texas is a party and municipal corporations, in the conservation and development of the water resources of this State, including the control, storing and preservation of its storm and flood waters and the waters of its rivers and streams, for all useful and lawful purposes by the acquisition, improvement, extension, or construction of dams, reservoirs and other water storage projects, including any system necessary for the transportation of water from storage to points of treatment and/or distribution, including facilities for transporting water therefrom to wholesale purchasers, or for any one or more of such purposes or methods.

(e) Any or all financial assistance as provided herein shall be repaid with interest upon such terms, conditions and manner of repayment as may be provided by law.

(f) While any of the Texas Water Development Bonds, or any interest on any of such bonds, is outstanding and unpaid, there is hereby appropriated out of the first moneys coming into the Treasury in each fiscal year, not otherwise appropriated by this Constitution, an amount which is sufficient to pay the principal and interest on such bonds that mature or become due during such fiscal year, less the amount in the sinking fund at the close of the prior fiscal year.

(g) The Legislature may provide for the investment of moneys available in the Texas Water Development Fund, and the interest and sinking funds established for the payment of bonds issued by the Texas Water Development Board. Income from such investment shall be used for the purposes prescribed by the Legislature. The Legislature may also make appropriations from the General Revenue Fund for paying administrative expenses of the Board.

(h) From the moneys received by the Texas Water Development Board as repayment of principal for financial assistance or as interest thereon, there shall be deposited in the interest and sinking fund for the bonds sufficient moneys to pay the interest and principal to become due during the ensuing year and sufficient to establish and maintain a reserve in said fund equal to the average annual principal and interest requirements on all outstanding bonds. If any year moneys are received in excess of the foregoing requirements then such excess shall be deposited to the Texas Water Development Fund, and may be used for administrative expenses of the Board and for the same purposes and upon the same terms and conditions prescribed for the proceeds derived from the sale of such State bonds.

(i) All Texas Water Development Bonds shall after approval by the Attorney General, registration by the Comptroller of Public Accounts of the State of Texas, and delivery to the purchasers, be incontestable and shall constitute general obligations of the State of Texas under the Constitution of Texas.
