When a drainage district sells bonds after assessing them, the board must calculate each year how much money needs to be collected to pay off the principal and interest for the bonds due in the upcoming two semiannual periods. This calculation must be officially recorded in the board's records.

As soon as the board makes an order, they must create two copies of it. One copy is kept by the board, and the other is certified and sent to the county treasurer of every county that has land affected by the assessment. This statement tells how much money needs to be collected that year to pay off the principal and interest of due bonds.

This law states that when calculating an assessment, an extra 15% must be added to the total amount to account for potential payment delays or failures.

This law requires that a financial statement includes an extra amount set by the board. This extra money is collected to create a sinking fund, which is used to pay off bonds before they are due.

This law section explains that to cover bond payments, both the interest and principal due must be collected, along with an extra 15% and any amount needed for a sinking fund. This total amount is called the installment for bonds and is collected and paid into a special bond fund.

This law outlines the payment schedule for land assessments related to certain bonds. Unless stated otherwise by the board's official decision, payments are made in two equal parts. The first part is due to county treasurers by the third Monday in October and becomes late if not paid by the first Monday in December. The second part can be paid anytime before the last Monday in April, at which point it also becomes overdue.

This law requires that the board gives the county treasurer a list each year to help with collecting installment payments for bonds. This list includes the reference number of each assessed piece of land, the name of the landowner as recorded in the original list, and the total amount assessed and due for that year on each piece of land.

This law requires that the list in question includes specific columns where payments, sales, and redemptions can be recorded.

This law requires the county treasurer to keep detailed records in the annual collection list. Specifically, they must note all payments made and the dates they were received. If a property is sold due to unpaid taxes, they include the word 'sold' and the sale date. If the sale is to the district, they record 'sold to the district' and the sale date. Additionally, if a property is redeemed, they must mark the word 'redeemed' and the date the payment was made.

This law requires the county treasurer to report to the board whenever the board asks. The report should include all entries the treasurer has made on the collection list.

If a payment on bonds becomes overdue, a penalty of $1 plus 20% of the overdue amount will be added to the payment. This extra charge will go into the bond fund.

This law requires county treasurers to transfer any money collected from bond installments or penalties due to late payments to the State Treasurer within 30 days. This money must then be credited to the bond fund related to the assessment.
