ST. PAUL, Minn. (AP) — Gov. Mark Dayton is asking for federal help after heavy flooding in southern Minnesota last month.

Dayton formally asked President Barack Obama to declare the flood damage a major disaster in a letter released Thursday. The storms and subsequent flooding on Sept. 21 and Sept. 22 caused an estimated $8.3 million in damage to public infrastructure.
