(1) A district may enter into repayment and other contracts with the United States under the terms of the federal reclamation laws in matters relating to federal reclamation projects, and may with respect to lands within its boundaries include in the contract, among others, an agreement that:

(a) The district will not deliver water by means of the project works provided by the United States to or for excess lands not eligible therefor under applicable federal law.

(b) As a condition to receiving water by means of the project works, each excess landowner in the district, unless his or her excess lands are otherwise eligible to receive water under applicable federal law, shall be required to execute a recordable contract covering all of his or her excess lands within the district.

(c) All excess lands within the district not eligible to receive water by means of the project works shall be subject to assessment in the same manner and to the same extent as lands eligible to receive water, subject to such provisions as the secretary may prescribe for postponement in payment of all or part of the assessment but not beyond a date five years from the time water would have become available for such lands had they been eligible therefor.

(d) The secretary is authorized to amend any existing contract, deed, or other document to conform to the provisions of applicable federal law as it now exists. Any such amendment may be filed for record under RCW 89.12.080.

(2) A district may enter into a contract with the United States for the transfer of operations and maintenance of the works of a federal reclamation project, but the contract does not impute to the district negligence for design or construction defects or deficiencies of the transferred works. Any contract, covenant, promise, agreement, or understanding purporting to indemnify against liability for damages caused by or resulting from the negligent acts or omissions of the United States, its employees, or agents is not enforceable unless expressly authorized by state law.
