Said board shall cause a copy of such order, duly certified, to be immediately filed for record in the office of the county recorder of each county in which any portion of such lands are situated.
If it shall appear, however, that more than one-third (1/3) of said votes are "Irrigation district-no," then a record of that fact shall be duly entered upon the minutes of said board, and all proceedings in regard to the organization of said district shall be void, and the expenses properly incurred thereunder may be collected on the bond provided for in section 43-104, Idaho Code.
From and after the date of such filing of said order of the board of county commissioners, the organization of such district shall be complete.

The board of directors so elected shall meet within thirty (30) days after their election and elect a director to hold the office of president, and shall appoint a secretary and treasurer, who shall perform the duties imposed upon such officers under this title.
