(a) Shall receive such pay for services as the court may allow, but shall be paid only for the time actually employed, and in no case shall the rate of pay exceed that allowed by the county surveyor.
(b) Shall oversee the construction and repair of dikes and dams.
(c) Shall see that all contracts are faithfully executed, and the work done in a thorough manner.
(d) After the dikes are completed, may employ the labor necessary to maintain them at the usual rate of wages allowed to laborers on the county road; provided, that in an emergency the county court may allow a higher rate of wages; and provided, further, that the county court may, with the approval of the advisory board, allow work on maintenance to be done by contract.
(2) The superintendent shall also, not less than 15 nor more than 30 days prior to the beginning of each fiscal year, file with the county court an estimate of the money required for the maintenance of the dikes and dams for the succeeding year. Such estimates added to any indebtedness there may be against the district shall be the basis of the tax for next year. The advisory board also shall file with the county court, on or before the 15th day preceding the beginning of each fiscal year, an estimate of the money required for the maintenance of the dikes and dams for the next succeeding year with a statement of the work in its opinion, required to be done, which estimates the court may consider in making its levy.
