Mich. Comp. Laws § 235.6
The highway commissioner shall report to the electors of the township at their annual meeting the amount of money expended by him during the year for such highway drainage, specifying the amount expended on each drain. He shall also recommend the raising of such sums as he may deem necessary for opening drains from the highway during the coming year, specifying each proposed drain and the probable amount needed for securing the right of way and opening the same. The money voted for this purpose by the electors of the township shall constitute a special highway drain fund, and shall be used for no other purpose. In case any money be left in the fund, after opening the drain for which it was raised, it may be used in opening any other highway drain in the township, or in cleaning out, when necessary, those already opened.
