Sec. 133. Whenever any proposed drain lies wholly or partly in an adjoining state, or the lands to be drained thereby lie partly in an adjoining state, application to lay out a drainage district and a petition for the construction of such drain may be made to any commissioner representing any county in this state in which any portion of such proposed drain or lands to be affected thereby lie, and the same proceedings shall be had touching the portion of such drain or the lands to be drained or affected thereby, lying within this state as are provided in this chapter in the case of drains and lands lying wholly within this state: Provided, That before any expense shall be incurred in relation to any such proposed drain, a voluntary release of the right of way to construct such portion of such drain as may lie without this state and an agreement to keep the same or permit the same to be kept clear from obstruction shall first be obtained from the parties owning lands outside of this state through which such drain or portion thereof is to pass, and such release and agreement shall be filed with the said drain commissioner and shall form a part of the record of his proceedings in the premises.
