Tex. Water Code § 55.194: TRANSFER OF WATER RIGHT.

If there is land in a district which has a water right from a source of supply acquired by the district but the land is difficult or impracticable to irrigate from that source of supply, the district may allow transfer of the water right to other land which is adjacent to the district. The adjacent land may be admitted to the district with the same right of water service as other land already in the district.
