N.D. Cent. Code § 61-24-05
Each member of the board of directors of the district shall hold office for a term of three years, and until the successor in office has been appointed and qualified, provided, that one-third of the board first appointed shall hold office for a term of three years, one-third for a term of two years, and the other directors shall hold office for a term of one year, from the first day of July next following the date of their appointment. Before assuming the duties of the office, each director shall take and subscribe the oath of office prescribed by law for civil officers. The district treasurer shall be bonded in such amount as the board may prescribe.
A member of the board of directors of the district elected in 1960 and thereafter shall hold office for a term of four years and until a successor has been duly elected and qualifies, but one-half of the directors elected at the general election in 1960 shall hold office for a term of two years, and one-half shall hold office for four years. Terms of office of directors elected at the first election shall be determined by lot. Directors elected after 1960 shall hold office for a term of four years. If the office of any director shall become vacant by reason of the failure of any director elected at any election to qualify or for any other reason, the successor shall be appointed to fill the vacancy by the board of county commissioners of the county in which the vacancy occurs. A director appointed to fill a vacancy shall hold office for the unexpired term of the director whose office has become vacant. A director shall, however, hold office until a successor has been elected and qualifies.
Members of the board of directors elected in 1960 shall assume office on the first Monday in January 1961 and shall replace all members of the board previously appointed. They shall meet at a time and place designated by the secretary of the replaced board of directors, and if that secretary is unable to act, by the secretary of the state water commission, and shall organize in the same manner as the first board of directors was organized. The secretary of the replaced board and any other person employed by that board shall continue in their positions until the new board shall otherwise provide.
