Tex. Water Code § 11.407

During the pendency of an appeal, the trial court shall limit the allocation and distribution of the water in its custody to the parties adjudicated to have a valid right to use the water. However, if any party prosecutes an appeal and files a supersedeas bond, the trial court shall make any necessary adjustments in the water allocations and allocate to that party the same amount of water that he received during the proceedings in the trial court.
