Okla. Stat. tit. 82, § 82-105.27: Unsafe works to be changed - United States works not

subject to inspection.

If the Board shall, in the course of its duties, find that any

works used for storage, diversion or carriage of water are unsafe

and a menace to life and property, it shall at once notify the owner

or his agent, specifying the changes necessary and allowing a

reasonable time for putting the works in safe condition. Upon the

request of any party, accompanied by the estimated cost of

inspection, the Board shall cause any alleged unsafe works to be

inspected. If they shall be found unsafe by the Board, the money

deposited by such party shall be refunded and the fees for

inspection shall be paid by the owner of such works; and, if not

paid by him within thirty (30) days after the decision of the Board,

shall be a lien against any property of such owner, to be recovered

by suit instituted by the district attorney of the county at the

request of the Board. The Board may, when necessary, inspect any

works for the storage, diversion or carriage of water and require

any changes necessary to secure their safety; and the fees for such

inspection shall be a lien on any property of the owner and shall be

subject to collection as provided herein; provided, that any works

constructed by the United States, or by its duly authorized

agencies, shall not be subject to such inspection while under the

supervision of officers of the United States. Provided, that liens

provided for in this section shall be superior in right to all

mortgages or other encumbrances, except ad valorem tax liens, placed

upon the land and the water appurtenant thereto or used in

connection therewith.
