Any municipality owning or permanently controlling land upon which a proposed dam is to be constructed may construct a dam thereon and across that portion of the Red River of the North which forms a part of the boundary common to the state of North Dakota and the state of Minnesota, for the purpose of conserving water for municipal, commercial, and domestic use, constructing in connection therewith such appliances, fishways, raceways, sluiceways, and wasteways as may be necessary or convenient for the proper construction and utility of such dam and as may be required by law. If required by law or treaty, the consent of the United States and of the state of Minnesota shall be obtained first.
