85-2-231. Temporary preliminary and preliminary decree. (1) A water judge may issue a temporary preliminary decree prior to the issuance of a preliminary decree if the temporary preliminary decree is necessary for the orderly adjudication or administration of water rights.
(2) (a) The water judge shall issue a preliminary decree. The preliminary decree must be based on:
(i) the statements of claim before the water judge;
(ii) the data submitted by the department;
(iii) the contents of compacts approved by the Montana legislature and the tribe or federal agency or, lacking an approved compact, the filings for federal and Indian reserved rights; and
(iv) any additional data obtained by the water judge.
(b) The preliminary decree must be issued within 90 days after the close of the special filing period set out in 85-2-702(3) or as soon after the close of that period as is reasonably feasible.
(c) The water judge may issue an interlocutory decree if an interlocutory decree is otherwise necessary for the orderly administration of water rights.
(3) A temporary preliminary decree may be issued for any hydrologically interrelated portion of a water division, including but not limited to a basin, subbasin, drainage, subdrainage, stream, or single source of supply of water, or any claim or group of claims at a time different from the issuance of other temporary preliminary decrees.
(4) The temporary preliminary decree or preliminary decree must contain the information and make the determinations, findings, and conclusions required for the final decree under 85-2-234.
(5) If the water judge is satisfied that the report of the water master meets the requirements for the preliminary decree and is satisfied with the conclusions contained in the report, the water judge shall adopt the report as the preliminary decree. If the water judge is not satisfied, the water judge may recommit the report to the master with instructions or modify the report and issue the preliminary decree.
(6) The department shall examine claims in basins that were verified rather than examined as ordered by the water court. The objection and hearing provisions of Title 85, chapter 2, part 2, apply to these claims. (Subsection (6) terminates June 30, 2028--sec. 10, Ch. 269, L. 2015.)
