Statutory Authority and Schedule

The commission by rule shall:

(1) adopt appropriate environmental flow standards for each river basin and bay system in this state that are adequate to support a sound ecological environment, to the maximum extent reasonable considering other public interests and other relevant factors;

(2) establish an amount of unappropriated water, if available, to be set aside to satisfy the environmental flow standards to the maximum extent reasonable when considering human water needs; and

(3) establish procedures for implementing an adjustment of the conditions included in a permit or an amended water right as provided by Sections 11.147(e-1) and (e-2).

Environmental flow standards adopted by the Commission must consist of a schedule of flow quantities, reflecting seasonal and yearly fluctuations that may vary geographically by specific location in a river basin and bay system.

The adoption schedule, as amended, requires environmental flow standards for the river and bay systems consisting of the Guadalupe, San Antonio, Mission, and Aransas Rivers and Mission, Copano, Aransas, and San Antonio Bays, and the Colorado and Lavaca Rivers and Matagorda and Lavaca Bays to be adopted by September 1, 2012. The rule process for the development of environmental flow standards for these two river basin and bay systems will begin on September 1, 2011, after receipt of environmental flow recommendation reports from the Basin and Bay Area Stakeholder Committees (BBASC) and Basin and Bay Expert Science Teams (BBEST).
