Okla. Stat. tit. 82 § 608
If it appears to the satisfaction of the court after having heard and determined all said exceptions that the estimated cost to the conservancy district of constructing the improvement contemplated in the official plan is less than the benefits appraised, then the court shall approve and confirm said appraisers' report as so modified and amended, and such findings and appraisals shall be final and incontestable as to property within the district. In considering the appraisals made by the board of appraisers, the court shall take cognizance of the official plan and of the degree to which it is effective for the purposes of the district. In case the court shall find that the estimated benefits appraised are less than the total costs to the conservancy district of the execution of the official plan, exclusive of interest or deferred payments, or that the official plan is not suited to the requirements of the district, it may at its discretion return said official plan to the directors of the district with the order for them to prepare new or amended plans, or it may disorganize the district after having provided for the payment of all expenditures by assessment prorated as provided herein, in the meantime holding the report of the appraisers in abeyance until such official plan has been prepared and refiled with the court clerk.
