No corporation, individual, or other drainage district, outside the limits of any district organized or operating under the terms of this chapter, shall drain into any ditch belonging to any district formed or operating under the terms of this chapter, without first paying compensation, to be ascertained by a jury in the circuit court or chancery court, for the use of said ditch, unless an agreement is reached between the commissioners of the district and the corporation, individual, or other drainage district desiring to use such ditch, as to such compensation. This and Section 51-29-77 shall not operate to interfere with vested rights to natural drainage.
