Of Florida’s 720 springs …
33 are first magnitude (orange).
Florida’s 1st, 2nd and 3rd magnitude springs
Another 342 are second and third order. Most of them are located where the Floridan Aquifer is exposed at the surface (shown in green above), or only shallowly submerged, thus allowing pressurized groundwater to wormhole its way to the surface. By definition, a first magnitude spring discharges at least 64 million gallons per day (100 cfs), or about 2.5 Fenway Parks (i.e. filled to the top of the 37.5 ft Green Monster). Silver Spring is currently flowing at about 20 Fenways per day. Not bad for a 65 ft diameter vent. Beach, spring, swamp or spring — it’s hard not to argue that seeing a spring isn’t the most impressive sight, and should be on the top of any tourist’s bucket list. As for seeing all 720, my recommendation is to start with Silver Spring or Weeki Wachee and go from there.
