N.D. Cent. Code § 58-02-09: Annexing parts of township divided by river from rest of township

If rivers, lakes, or creeks divide a civil or congressional township and make it inconvenient to do township business, the board of county commissioners of the county in which the township is located may annex that part of the township segregated by such river, lake, or creek to an adjoining township in the same county upon the petition of not less than two-thirds of the qualified electors residing in the part of the township so segregated.
