It seems that lately the discharge of Madison Blue Spring has fallen slightly below the official threshold of the 1st magnitude springs. The mean discharge of a 1st magnitude spring should be at least 100 cubic feet or 2,832 litres per second. Measurements in Madison Blue Spring from 2002 to 2023 show a mean discharge of 2,763 l/s (97.6 cubic feet) (2.).
This does not diminish the popularity of this stunning natural wonder. The spring is situated in a very scenic area, and has formed a natural basin of incredibly clear, blue-green coloured water. The spring pool has a diameter of about 24.4 m and is up to 9.1 m deep. A limestone bluff is on its western bank.
The spring forms a pool that is connected to the nearby Withlacoochee River by a roughly 45 m long spring run with a lively stream in it. This short “river” is about 6 m wide and 1 m deep. The colour of the spring water contrasts with the tannic, brownish water of the river.
The spring has formed in Oligocene and Eocene limestone.
When there are floods in the Withlacoochee River, the water also rises in the spring pool – sometimes up to 6 metres! During the flood, the flow is reversed and slightly acidic river water enters underground. Throughout the millennia, this inflow of acidic water has created a large, impressive underwater cave system. Some 7.775 km of cave passages have been explored through the vent of the spring. The depth of the cave reaches 43 m.
Madison Blue Spring is included in the list of Outstanding Florida Springs, along with 29 other springs of the state. Around the spring, Madison Blue Spring State Park has been created – it was established in 2000 after the sale of this formerly private land to the state. This is a well-known site for cave divers, but also used for swimming, tubing, paddling. The water temperature in the spring is constant – 21.3 ° C.
Unfortunately, the nitrate pollution in the water of the spring has gradually increased (3.).

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.
The United States of America is one of the largest countries in the world and offers a wide array of diverse attractions: many are unsurpassed in the world. Highlights of the United States are cliffs, canyons, and rock formations, several impressive downtowns of cities with numerous skyscrapers as well as a rich array of geothermal features, and the giant forest of California.
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.

FLORIDA SPRINGS FROM TOP TO BOTTOM: Your Guide to the Best of Florida’s Springs, Parks and Recreations
The author started gathering information for this unique guidebook of Florida Springs over 40 years ago. In 1973 Robert F. Burgess began diving and photographing the underwater caves associated with Florida’s labyrinthine freshwater springs long before scuba divers had such things as depth gauges, personal flotation devices, or cave divers training programs. He attributes his survival in what has been called “the world’s most dangerous sport” to the fact that he always stayed within sight of the way out of these underwater sites.
