A registration may include more than one drainage system

Any drainage begun prior to July 1, 1988, and challenged by an affected landowner in a court of law or before a board or commission within two years of filing, may not become vested until and unless a final decision has been reached in favor of such drainage. Any commission decision may be appealed to the board within twenty days. Any board decision may be appealed to the circuit court of the county wherein the dispute arose within twenty days. Any circuit court decision may be appealed in the same manner as any other circuit court decision. If such final decision has been reached, including final decision on any appeal, the owner of the drainage right shall record the final decision within thirty days in order for the right to become vested. No county, township, or municipality is required to register its natural drainage rights. Source: SL 1985, ch 362 , § 31; SL 1986, ch 379 , § 1; SL 1987, ch 338 ; SL 1991, ch 374 .
