All moneys held in the capital reserve fund, except as hereinafter provided, shall be used solely for the payment of the principal of bonds or notes secured by the fund, the purchase or redemption of the bonds or notes, the payment of interest on the bonds or notes, or the payment of any redemption premium required to be paid when the bonds or notes are redeemed prior to maturity. Any income from the capital reserve fund may be transferred to other funds or accounts to the extent the transfer does not reduce the amount of the capital reserve fund below the capital reserve fund requirement in this chapter.
