Missouri Revised Statutes Title XL. Additional Executive Departments § 644.042. Losing streams, a rebuttable presumption, how determined

The commission may adopt by rule a rebuttable presumption that any stream segment located within one mile upstream of a stream segment that has been determined by the commission to be a losing stream, as defined by the commission by rule, is also a losing stream until determined otherwise by the commission based upon the evidence. Except for the presumption authorized by the preceding sentence, the commission shall not adopt any presumption that any other stream segments are losing streams, and shall make any such determinations based on data applicable to such stream segments.
