Provide an overview of the state law and the specific work in the cypress basinInvite you to our next set of meetings – December 2-4 in JeffersonRequest the support of the Regional Water Planning Group in its statement “environmental water needs”

Senate Bill 3: Consensus Bill Enacted in 2007

  • Sec. 11.1471. Environmental Flows Standard & Set Asides (a)  The commission (TCEQ) by rule shall:

  • (1)  adopt appropriate environmental flow standards for each river basin … 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….


Existing goal in texas law

Existing Goal In Texas Law

 Maintaining the biological soundness of the state's rivers, lakes, bays, and estuaries is of great importance to the public's economic health and general well-being. (Section 11.0235(b))


How sb 3

How – SB 3

  • The legislature finds that:

  • (1)  in those basins in which water is available for appropriation, the commission should establish an environmental set-aside below which water should not be available for appropriation; and

  • (2)  in those basins in which the unappropriated water that will be set aside for instream flow and freshwater inflow protection is not sufficient . . . a variety of market approaches, both public and private, for filling the gap must be explored and pursued.


How continued

How (continued)

  • The legislature finds that recommendations for state action to protect instream flows and freshwater inflows should be developed through a consensus-based, regional approach involving balanced representation of stakeholders and that such a process should be encouraged throughout the state.


How much

How Much

Environmental Flow Standard: …adequate to support a sound ecological environment, to the maximum extent reasonable considering other public interests and other relevant factors;

  • Set Aside: an amount of unappropriated water, if available, … to satisfy the environmental flow standards to the maximum extent reasonable when considering human water needs.

Senate bill 3

Senate Bill 3

In a “basin” for which there is no ongoing flow process, the law also allows,

“an effort to develop information on environmental flow needs and ways in which those needs can be met by a voluntary consensus-building process.” Sec. 11.02362(e).


Goals of the cypress basin work

GOALS OF THE CYPRESS BASIN WORK

Voluntary effort to determine the amounts, frequency, and variation of instream flows needed in the watershed - based on sound science and a balancing of the needs and interests of stakeholders - to:

1. Protect the ecological, social and economic values provided by instream flows in the system (2004)

2. Assist with the efforts to address water quality impairments in the watershed protection plan.(added 2006)


Examples of objectives

EXAMPLES OF OBJECTIVES

  • SB 3 Set Aside i.e., a state approved reservation of an environmental flow regime in the watershed, and

  • Revised Release Pattern for Lake O' the Pines: to provide a more natural pattern of flows downstream in Big Cypress and into Caddo Lake.

  • Water Quality Improvements: assure base flows needed for discharge of treated wastewaters.
