(a) If upon view it shall appear to the court that none of the evils provided against in § 18-15-708 are likely to ensue, the court shall then consider whether, all circumstances weighed, it is reasonable that the permission to erect the dam as prayed for should be given, and thereupon make an order, giving permission or not accordingly.
(b) The order and decree authorized by subsection (a) of this section and § 18-15-712 and the rights and privileges thereby granted shall, in all cases, be upon and subject to the following conditions:
(1) Such conditions in reference to the obstructions of the passage of fish as the court shall think proper to impose;
(2) That all damages and valuations made and assessed by the jury shall be paid; and
(3) That the dam and mills or other machinery shall be commenced within one (1) year, and they shall be finished and ready for business within three (3) years from the date of the order of permission.
