Subchapter D. Permits to Use State Water
Section 11.147. Effects of Permit on Bays and Estuaries and Instream Uses

Sec. 11.147. EFFECTS OF PERMIT ON BAYS AND ESTUARIES AND INSTREAM USES. (a) In this section, "beneficial inflows" means a salinity, nutrient, and sediment loading regime adequate to maintain an ecologically sound environment in the receiving bay and estuary system that is necessary for the maintenance of productivity of economically important and ecologically characteristic sport or commercial fish and shellfish species and estuarine life upon which such fish and shellfish are dependent.
(b) In its consideration of an application for a permit to store, take, or divert water, the commission shall assess the effects, if any, of the issuance of the permit on the bays and estuaries of Texas. For permits issued within an area that is 200 river miles of the coast, to commence from the mouth of the river thence inland, the commission shall include in the permit any conditions considered necessary to maintain beneficial inflows to any affected bay and estuary system, to the extent practicable when considering all public interests and the studies mandated by Section 16.058 as evaluated under Section 11.1491.
(c) For the purposes of making a determination under Subsection (b) of this section, the commission shall consider among other factors:
(1) the need for periodic freshwater inflows to supply nutrients and modify salinity to preserve the sound environment of the bay or estuary, using any available information, including studies and plans specified in Section 11.1491 of this code and other studies considered by the commission to be reliable; together with existing circumstances, natural or otherwise, that might prevent the conditions imposed from producing benefits;
(2) the ecology and productivity of the affected bay and estuary system;
(3) the expected effects on the public welfare of not including in the permit some or all of the conditions considered necessary to maintain the beneficial inflows to the affected bay or estuary system;
(4) the quantity of water requested and the proposed use of water by the applicant, as well as the needs of those who would be served by the applicant;
(5) the expected effects on the public welfare of the failure to issue all or part of the permit being considered; and
(6) for purposes of this section, the declarations as to preferences for competing uses of water as found in Sections 11.024 and 11.033, Water Code, as well as the public policy statement in Section 1.003, Water Code.
(d) In its consideration of an application to store, take, or divert water, the commission shall include in the permit, to the extent practicable when considering all public interests, those conditions considered by the commission necessary to maintain existing instream uses and water quality of the stream or river to which the application applies. In determining what conditions to include in the permit under this subsection, the commission shall consider among other factors:
(1) the studies mandated by Section 16.059; and
(2) any water quality assessment performed under Section 11.150.
(e) The commission shall include in the permit, to the extent practicable when considering all public interests, those conditions considered by the commission necessary to maintain fish and wildlife habitats. In determining what conditions to include in the permit under this subsection, the commission shall consider any assessment performed under Section 11.152.
(e-1) Any permit for a new appropriation of water or an amendment to an existing water right that increases the amount of water authorized to be stored, taken, or diverted must include a provision allowing the commission to adjust the conditions included in the permit or amended water right to provide for protection of instream flows or freshwater inflows. With respect to an amended water right, the provision may not allow the commission to adjust a condition of the amendment other than a condition that applies only to the increase in the amount of water to be stored, taken, or diverted authorized by the amendment. This subsection does not affect an appropriation of or an authorization to store, take, or divert water under a permit or amendment to a water right issued before September 1, 2007. The commission shall adjust the conditions if the commission determines, through an expedited public comment process, that such an adjustment is appropriate to achieve compliance with applicable environmental flow standards adopted under Section 11.1471. The adjustment:
(1) in combination with any previous adjustments made under this subsection may not increase the amount of the pass-through or release requirement for the protection of instream flows or freshwater inflows by more than 12.5 percent of the annualized total of that requirement contained in the permit as issued or of that requirement contained in the amended water right and applicable only to the increase in the amount of water authorized to be stored, taken, or diverted under the amended water right;
(2) must be based on appropriate consideration of the priority dates and diversion locations of any other water rights granted in the same river basin that are subject to adjustment under this subsection; and
(3) must be based on appropriate consideration of any voluntary contributions to the Texas Water Trust, and of any voluntary amendments to existing water rights to change the use of a specified quantity of water to or add a use of a specified quantity of water for instream flows dedicated to environmental needs or bay and estuary inflows as authorized by Section 11.0237(a), that actually contribute toward meeting the applicable environmental flow standards.
(e-2) Any water right holder who makes a contribution or amends a water right as described by Subsection (e-1)(3) is entitled to appropriate credit for the benefits of the contribution or amendment against the adjustment of the holder's water right under Subsection (e-1).
(e-3) Notwithstanding Subsections (b)-(e), for the purpose of determining the environmental flow conditions necessary to maintain freshwater inflows to an affected bay and estuary system, existing instream uses and water quality of a stream or river, or fish and aquatic wildlife habitats, the commission shall apply any applicable environmental flow standard, including any environmental flow set-aside, adopted under Section 11.1471 instead of considering the factors specified by those subsections.
(f) On receipt of an application for a permit to store, take, or divert water, the commission shall send a copy of the permit application and any subsequent amendments to the Parks and Wildlife Department. At its option, the Parks and Wildlife Department may be a party in hearings on applications for permits to store, take, or divert water. In making a final decision on any application for a permit, the commission, in addition to other information, evidence, and testimony presented, shall consider all information, evidence, and testimony presented by the Parks and Wildlife Department and the board.
(g) The failure of the Parks and Wildlife Department to appear as a party does not relieve the commission of the requirements of this section.
