Sec. 74. (a) This section applies to a county having a population of more than four hundred thousand (400,000) and less than seven hundred thousand (700,000).

(b) Each year, the county shall levy the tax authorized by section 73 of this chapter at a rate on each one hundred dollars ($100) of assessed valuation that will yield three hundred thousand dollars ($300,000) per year.

(c) The county auditor shall determine a particular watershed's part of the receipts from the tax authorized by this section by multiplying the total tax receipts by a fraction determined by the county surveyor.  The numerator of the fraction is the number of acres in the particular watershed, and the denominator is the total number of acres in all of the watersheds in the county.  The auditor shall annually distribute these amounts to the watersheds in the county.

(d) The county legislative body shall annually appropriate, for use in the county in each of these watersheds, at least eighty percent (80%) of the watershed's part of the tax receipts.
