As soon as the several county commissions shall be furnished with the proper description of lands contemplated in section 241.010, they may have said overflowed and swamp lands drained and reclaimed, so as to render them tillable, or otherwise subservient to the purposes of sections 241.010 to 241.280, and for that purpose may appoint one or more drainage and reclamation commissioners, who shall, under the direction of the county commission, superintend the draining and surveying of said lands.
