Environmental Reviews of Water Right Applications

Instream Uses Staff of the Resource Protection Team perform environmental reviews of water right applications. In river basin and bay systems with adopted flow standards, staff applies the standards to applications for new appropriations of water. To see the adopted rules for these basins, see Texas Administrative Code (TAC), Title 30 Chapter 298. For more information on the Environmental Flows (Eflows) process, see the Environmental Flows page. In basins with no standards, staff evaluates available information related to a proposed water project to consider potential impacts to fish and wildlife habitat, water quality, instream uses associated with the affected body of water and downstream areas. If the project is within 200 river miles from the Texas coast, freshwater inflows to bays and estuaries are also addressed. Several assessment techniques may be used to evaluate potential effects of actions associated with water right applications. Once the information is gathered and assimilated, a recommendation is made as to the type of restriction or condition which might be required to satisfy environmental concerns. Texas Water Code, §§11.042, 11.147, 11.1491, 11.150, 11.152 TAC, Title 30 Chapter 297, Sections 297.53 through 297.56Exit the TCEQ.

Information needed with an application: When preparing a water right permit application for TCEQ submittal, applicants are requested to provide information described in the Supplemental Environmental Information Sheet.

Texas Instream Flow Program

In 2001, the 77th session of the Texas Legislature passed Senate Bill 2 (S.B.2), which directed Texas Parks and Wildlife Department (TPWD), the Texas Commission on Environmental Quality (TCEQ), and the Texas Water Development Board (TWDB), in cooperation with other appropriate agencies, to "…jointly establish and continuously maintain an instream flow data collection and evaluation program…" In addition, the agencies were directed to "…conduct studies and analyses to determine appropriate methodologies for determining flow conditions in the state rivers and streams necessary to support a sound ecological environment."
