(70 ILCS 605/2-12) (from Ch. 42, par. 2-12)
    Sec. 2-12. Interference by Landowner-Penalty-Exceptions.
    The landowner shall not wilfully and intentionally interfere with any ditches or natural drains which cross his land in such manner that such ditches or natural drains shall fill or become obstructed with any matter which shall materially impede or interfere with the flow of water. If the landowner violates the provisions of this section he commits a petty offense. Each day's violation shall be a separate offense. Provided, this Section does not apply to any ditches or drains which are entirely on the land of the landowner, nor does this Section prohibit the construction of artificial impoundments or the temporary interruption of the flow of water by such impoundments.
