(a) This section applies to:
(1) claims of riparian water rights;
(2) claims under § 11.143 of this code to impound, divert, or use state water for other than domestic or livestock purposes, for which no permit has been issued;
(3) claims of water rights under the Irrigation Acts of 1889 and 1895 which were not filed with the State Board of Water Engineers in accordance with the Irrigation Act of 1913, as amended; and
(4) other claims of water rights except claims under permits or certified filings.
(b) Any claim to which this section applies shall be recognized only if valid under existing law and only to the extent of the maximum actual application of water to beneficial use without waste during any calendar year from 1963 to 1967, inclusive. However, in any case where a claimant of a riparian right has prior to August 28, 1967, commenced or completed the construction of works designed to apply a greater quantity of water to beneficial use, the right shall be recognized to the extent of the maximum amount of water actually applied to beneficial use without waste during any calendar year from 1963 to 1970, inclusive.

(c) On or before September 1, 1969, every person claiming a water right to which this section applies shall file with the commission a statement setting forth:
(1) the name and address of the claimant;
(2) the location and the nature of the right claimed;
(3) the stream or watercourse and the river basin in which the right is claimed;
(4) the date of commencement of works;
(5) the dates and volumes of use of water; and
(6) other information the commission may require to show the nature and extent of the claim.
(d) A person who files a statement as provided in this section shall certify under oath that the statements made in support of his claim are true and correct to the best of his knowledge and belief.
(e) A claimant who desires recognition of a right based on use from 1968 to 1970, inclusive, as provided in Subsection (b) of this section shall file an additional sworn statement on or before July 1, 1971.
(f) The commission shall prescribe forms for the sworn statements required by this section, but use of the commission forms is not mandatory.
(g) On or before January 1, 1968, and June 1, 1969, the commission shall cause notice of the requirements of this section to be published once each week for two consecutive weeks in newspapers having general circulation in each county of the state and by first-class mail to each user of surface water who has filed a report of water use with the commission.
(h) On sworn petition, notice, and hearing as prescribed for applications for permits and upon finding of extenuating circumstances and good cause shown for failure to timely file, the commission may authorize the filing of the sworn statement or statements required by this section until entry of a preliminary determination of claims of water rights in accordance with § 11.309 of this code which includes the area described in the petition or, if a preliminary determination has not been entered, until September 1, 1974.
(i) Since the filing of all claims to use public water is necessary for the conservation and best utilization of the water resources of the state, failure to file a sworn statement in substantial compliance with this section extinguishes and bars any claim of water rights to which this section applies.
(j) A sworn statement submitted under this section is binding on the person submitting it and his successors in interest, but is not binding on the commission or any other person in interest.
(k) Nothing in this section shall be construed to recognize any water right which did not exist before August 28, 1967.
(l) This section does not apply to use of water for domestic or livestock purposes.
