Current through Reg. 50, No. 13; March 28, 2025
(a) The Guadalupe, San Antonio, Mission, and Aransas Rivers, their associated tributaries, Mission, Copano, Aransas, and San Antonio Bays, and the associated estuaries are substantially sound ecological environments.
(b) For the Guadalupe, San Antonio, Mission, and Aransas Rivers, and their associated tributaries, the commission finds that these sound ecological environments can best be maintained by a set of flow standards that implement a schedule of flow quantities that contain subsistence flow, base flow, and high flow pulses at defined measurement points. Minimum flow levels for these components will vary by season and by year since the amount of precipitation and, therefore, whether a system is in subsistence or base flow conditions, will vary from year to year and within a year from season to season, and the number of pulses protected will also vary with the amount of precipitation.
(c) For Mission, Copano, Aransas, and San Antonio Bays, the commission finds that the sound ecological environment of these bays can best be maintained by a set of freshwater inflow standards that include variable freshwater inflow quantities and that incorporate inflow and frequency targets at which specific levels of freshwater inflow occur, which are used for the sole purpose of providing additional freshwater inflows to Mission, Copano, Aransas, and San Antonio Bays through voluntary strategies.
