Nature's unfinished work in the Wisconsin drift areas of Iowa has left the lands peculiarly subject to submergence in times of heavy precipitation. The magnitude of the drainage projects which would be required to carry out the incomplete work of Nature's young river systems, for a long time held back the development of drainage. Recent legislation, making possible the creation of drainage districts upon the petition of a reasonable number of land holders interested, has led to a most rapid growth in farm land drainage.
