Wyo. Stat. § 41-3-775
The board in making the annual assessments and levies as herein provided, shall take into account the maturing indebtedness for the ensuing year as provided in its contracts and/or the maturing of bonds and interest on all bonds, and deficiencies and defaults of prior years, and shall make ample provision for the payment thereof. In case the proceeds of such levies and assessments made under the provisions of this act, together with other revenues of the district, are not sufficient to punctually pay the annual installments on its contracts and/or bonds, and interest thereon and to pay defaults and deficiencies, then the board shall make such additional levies of taxes and/or assessments as may be necessary for such purposes and notwithstanding any limitations by contract, order, tax lien, or otherwise, such taxes and assessments shall be made to continue until the indebtedness of the district shall be fully paid; provided, however, that the amount of such additional levies of taxes under class A as provided in W.S. 41-3-770, shall not in any one (1) year exceed an amount that would be raised by a levy of one-half (1/2) mill against the assessed value of such property as fixed for general tax purposes; provided, that such levies for defaults and deficiencies shall not at any time be so made as to impose upon class A as herein provided, payments in excess of twenty-five percent (25%) of the anticipated revenue from all sources to be raised for the specific purpose of payment of existing defaults and deficiencies; and provided further, that in making such additional levies and/or assessments, the board shall take into account all sources of revenue and equitably distribute the burden of such defaults and deficiencies according to the uses and benefits as provided in this act.
