46A-13-9. Contract for joint action with adjoining state for drainage or flood control. The commissioners of a drainage district formed pursuant to this chapter may, if necessary or expedient to carry out the purposes of this chapter, enter into a contract or agreement with the court, board, or tribunal of an adjoining state having authority relative to drainage matters in that state, including the right to raise, lower, or fix the stage of water in boundary waters, or with the United States government under its authorized authority. The contract or agreement shall be for joint action with the adjoining state for drainage or flood control measures that cause benefits or damages to, or otherwise affect, property in this state and the adjoining state. The provisions of this section apply to any lake, pond, or other body of water, or any river, stream, or watercourse that forms to any extent a boundary line between this state and any other state, and to any land included within a natural drainage basin lying along or extending across the boundary line of the state. The contract or agreement may be for the following purposes:

(1) To facilitate drainage into or from, or to control to any extent flood waters into, through, or from any such lake, pond, body of water, river, stream, or watercourse, or into or from any such land;

(2) For purposes of flood control, to raise, lower, or otherwise affect the stage or depth of water;

(3) For the joint establishment and construction of all necessary ditches, drains, canals, dikes, levees, dams, locks, spillways, or other structures necessary to provide a proper watercourse;

(4) For deepening, widening, and straightening of the channels of any river, stream, or watercourse;

(5) For controlling by dikes or levees the flow of water in a manner necessary to effectuate the provisions of this chapter; and

(6) For securing and providing the necessary drainage facilities and control of flood waters into, through, and from the boundary waters and the rivers, streams, or ditches connected with the boundary waters and for properly draining any natural drainage basin.

In order to implement the contract or agreement the commissioners may determine the damages and benefits that may result to property located within the drainage district, and may provide funds to implement the contract or agreement by special assessment upon the property benefited according to the benefits received, as provided in this chapter.
