Description: Digitization provided by the USF Libraries Digitization Center. Rare Maps. This is a detail map of the Everglades and Lake Okeechobee showing the area's proposed drainage and artesian flow, circa 1913. Text from the main map states, "The inclusion of the Everglades within the flowing belt is hypothetical, no deep wells having been drilled as yet within this area. It seems probable however, that a flow will be obtained in the Everglades, although at a considerable depth. Whether or not flowing wells will be obtained on the mainland of extreme Southern Florida is undetermined." Source: Elias Howard Sellards, Ph.
