Okla. Stat. tit. 82, § 569
When it is determined to let the work of a conservancy district by contract, contracts in amounts to exceed Seven Thousand Five Hundred Dollars ($7,500.00) shall be advertised after notices calling for bids have been published once a week, for three (3) consecutive weeks completed on date of last publication, which shall not be less than fourteen (14) days from the first publication, in at least one newspaper in each county, where any part of the work under terms of the contract is to be performed, and the board may let said contract to the lowest and best bidder, who shall give a good and approved bond, with ample security, equal in amount to the total of the bid, conditioned on the carrying out of the contract, to completion, and shall file the said bond and contract with the secretary of said district in amount and conditions as provided by law, conditioned on the carrying out of the contract. But this contract shall not be let to another than the lowest bidder until a hearing before the court has been had with notice to all parties interested, as ordered by the court and an order obtained from the court. Such contract shall be in writing, and shall be accompanied by or shall refer to plans and specifications for the work done, prepared by the chief engineer. Said contract shall be approved by the board of directors and signed by the president of the board and by the contractor, and shall be executed in duplicate. Provided, that in case of sudden emergency when it is necessary in order to protect the district, the advertising of contracts may be waived upon the unanimous consent of the board of directors, with the approval of the court or the judge in vacation; and provided, further, that the action of said board of directors in awarding a contract shall, upon application of any interested taxpayer, be reviewed by the district court at a time and place specified by the judge of said court and the order of said district court may be appealed from, by either the board of directors or any interested taxpayer, to the Supreme Court of the State of Oklahoma in the same manner as other appeals under civil procedure.
