The resulting flood covered an area of hundreds of square miles with water that in some places was over 20 ft (6 m) deep. Houses were floated off of their foundations and dashed to pieces against any obstacle they encountered. Most survivors and bodies were washed out into the Everglades where many of the bodies were never found. Agricultural losses in the area surrounding Lake Okeechobee were also significant, with virtually all crops destroyed and over 150 tractors suffering damage.
