If, after hearing the evidence, the court finds that the report of the temporary commissioners should be modified in any particular to provide the best drainage or protection for the lands in the proposed district, with the least damage and greatest benefit to all the lands affected, and the court is sufficiently informed in the premises, it shall modify the same in accordance with such finding. If the court finds that the report should be so modified but is not sufficiently informed to make the modifications itself, then it shall refer the report back to the temporary commissioners and may give them specific directions for modifying their report. If the report is thus referred back to the temporary commissioners, the court shall continue the hearing to a day certain for the filing of the modified report. Successive continuances may be granted, and no further notice shall be required.
