Map Series No 4 November, 1962 - Piezometric Surface And Areas Of Artesian Flow Of The Floridan Aquifer In Florida July 6-17, 1961

Observation well (Hydrographs are shown for these selected wells) Contour represents the height, in feet referred to mean sea level, to which water would have risen in tightly cased wells that penetrate the major water- bearing formations in the Floridan aquifer, July 6-17, 1961. Contour interval 10 and 20 feet, changing at mean sea level. [ ] Extent and distribution of flow areas vary with fluctuations of the piezometric surface, particularly in areas of heavy Relatively small areas of artesian flow are not included immediately adjacent to and paralleling the coast and many of the major rivers and springs
