N.D. Cent. Code § 61-24.3-16
To identify and distinguish the revenues received by the commission from water user entities for replacement and extraordinary maintenance of the southwest pipeline project, there shall be maintained, as a part of the moneys of the state received and kept by the state treasurer, a fund to be designated as the southwest pipeline project reserve fund for replacement. All moneys received by the state treasurer from the commission, whether from payments made by water user entities for replacement and extraordinary maintenance of the southwest pipeline project or otherwise, which shall be by law or by other authoritative designation made applicable to replacement of the southwest pipeline project, shall be kept by the state treasurer in such fund distinct from all other moneys and shall be disbursed by the state treasurer only for the particular purpose or purposes for which the moneys were received, and no other appropriations shall ever be made of the moneys in the fund. This section shall not be construed as preventing the state treasurer from depositing the moneys in the Bank of North Dakota.
