The office of director shall become vacant when any member ceases to reside in the county from which the director was appointed. In the event a vacancy occurs in said office by reason of death, resignation, removal, or otherwise, it shall be filled by the board of county commissioners of the county from which said member originally came. Each director shall take an oath or affirmation in accordance with section 24-12-101. The board of directors of said district shall appoint a secretary and a treasurer. The same individual may, at the election of the board, hold both of said offices. The board shall likewise hire such other employees, including engineers and attorneys, as may be required to properly transact the business of the district, and said board is authorized to provide for the compensation of the secretary and treasurer and other appointees. The treasurer shall be required by the board to give bond with corporate surety in such amount as the board may fix and which it deems sufficient to protect the funds in the hands of the treasurer or under the treasurer's control. Such bond is subject to the approval of the board.
