WorldBlue  In short

The giant Volusia Blue Spring is an unusual natural landmark. The deep blue-green basin over this spring seems to be cut with a knife – there is a deep fissure across the spring where lucid springwater gushes out. One can dive in this fissure up to 38 m deep!

Description of Volusia Blue Spring

The basin above the fissure is some 6 meters deep – but nevertheless, there is seen a bulge and boil on the surface! Spring discharges from the Upper Floridan Aquifer, Middle and Upper Eocene limestone. The taste of water is salty, the temperature – 23 °C.

The spring forms a short river which after some 620 m falls in the Middle St. John River.

The area is very picturesque – banks of the spring are covered with virgin forest, there are limestone cliffs along the stream and in the middle – a stream with lucid, bluish water!

Manatees and snails

Volusia Blue Spring is the only place where lives Blue Spring hydrobe Aphaostracon asthenes – a small freshwater snail. Here have been observed also 32 species of fish, several species of turtles.

But the most noticeable animal here is the Florida manatee (Trichechus manatus latirostris). This is the main winter refuge for the population of Middle St. Johns River manatees whose number is increasing. If in the early 1970ies in the spring during the winter lived 11 manatees, in 2011-2012 their number increased to 400.

Nature conservation authorities have divided the spring run. The upper part, near the spring, is given to people. In holidays the spring is filled with swimmers, divers, snorkelers. But further down the stream comes the realm of manatees where people cannot swim. Only at the mouth of the spring run visitors are allowed to look at manatees in the water.

Environmental challenges

Both the increasing number of human visitors and manatees create water pollution in the spring run. There appear more and more filamentous algae (characteristic of polluted water), water clarity decreases.

Another worrying tendency is the decrease in water amount due to the increased pumping of the groundwater in the nearby cities. If in 1930 – 1980 the output was around 4,590 l/s, in 2007 – 2017 it was just 3,820 l/s.

Wonders of Florida

Florida is the tropical paradise of the mainland United States. Over the last century, it has experienced fabulous changes, turning from a forgotten, swampy badland into a densely populated and rich land. Highlights of Florida include the architecture of the late 19th and 20th centuries as well as its giant springs and caves.

Every year there are reported exciting discoveries of new caves and discoveries of new qualities such as cave paintings in the ones known before. But there still is a feeling that our knowledge covers just a small part of all these monuments of nature.

Though, those which are known to us, offer a surprising diversity of unusual features and impressive sights.

Powerful natural freshwater springs belong to the most fascinating monuments of nature. Even more exciting is the diversity of unusual springs – mineral springs, hot springs, submarine springs as well as the unusual black smokers. Especially beautiful are such natural rarities as travertine, silica, or salt terraces created by warm and hot springs and, especially, geysers.
