Tex. Water Code § 36.118

(a) A district may require the owner or lessee of land on which an open or uncovered well is located to keep the well permanently closed or capped with a covering capable of sustaining weight of at least 400 pounds, except when the well is in actual use.

(b) As used in this section, "open or uncovered well" means an artificial excavation dug or drilled for the purpose of exploring for or producing water from the groundwater reservoir and is not capped or covered as required by this chapter.

(1) the existence of the well;

(2) the legal description of the property on which the well is located;

(3) the approximate location of the well on the property;
