If in any year the board of directors fails to levy assessments for the repayment of indebtedness in amounts sufficient to meet a payment or payments falling due, the lender may bring an action in the district court of any county in which the district is situated to compel the board to levy assessments in amounts sufficient to insure the payment thereof. In the event that the annual assessment to meet a payment or payments falling due will be unreasonably high, the district court may, in the alternative, enter an order requiring that moneys received by the district in payment of assessments for all purposes be first expended for the repayment of that portion of the indebtedness falling due.
