If the owner or user of any dam refuses or fails to construct and maintain the means or equipment for the free passage of fish when ordered by the department, the department may cause the same to be constructed over or through the dam at the place in the dam that will cause the least injury to the water power, and the expense of the construction of the means for the free passage of fish shall be certified by the department to the county board of commissioners of the county in which the dam is located, and the expense shall be audited by the county board of commissioners and shall be paid from the general fund of the county. The county board of commissioners of any county, upon auditing and allowing the expense, shall order, by resolution, the supervisor of the township or ward in which the dam is situated to spread the expense upon the assessment roll of the township or ward as a tax against the property to which the dam is appurtenant and against the owners of the property to be collected in the same manner as other township taxes and paid over to the county treasurer or returned as delinquent in accordance with law.
