Directions

From Highway 90 in Marianna, go north on State Road 71. A Wal-Martis on the corner at right. (Note that the southern part of 71 that leadsto I-10 is down the road to the west.) After about a mile, past the farmequipment building, Blue Spring Road forks off to the right. Go about 3miles and you will see the sign to Blue Spring Park on the right.

Spring Description

The circular spring basin lies in a depression and is approximately250 feet in diameter.  Water issues from a large (8 feet high by 30feet wide) and accessible cave opening.  There is an underwater cavern at the spring that extends several thousand feet.  The water forms the 4.4-mile-long Merritt's Mill Pond and is dotted by several springs(see below).  The southern end of the pond is dammed up at U.S. 90and can be seen while driving through Marianna.

A fence divides the spring area from the pond and prevents boat access into the spring basin. The water is very clear and deep blue over the cave entrance, which is directly beneath the dive platform and diving board about 15 feet deep. Much of the bottom in the spring pool is sandy, but there are also areas of elodea/hydrilla intrusion in the center of the pool and near the fence that separates the pool from the "Pond."  Swimming and diving in the spring can cloud the water.

The beach area above the spring is sandy, but does not extend down tothe water and has a wooden barrier (railroad ties) to help keep sand from eroding into the spring basin.

Land in the spring's watershed, which extends into Alabama, is about50/50 agriculture and forest.  Water tests indicate that Jackson BlueSpring has the second highest concentration of nitrates in its water of any first magnitude spring in Florida--3 mg/liter.  Tests indicate that half the nitrate is absorbed or sinks to the bottom in the 4-mile pond.  In addition, the spring areas has the most strongly inorganic isotype ratio of any measured spring.  On more recent visits,(2000-2003),the water more more geenish than blue, and there were higher concentrations of algae on the bottom.  It is estimated that water flowing out of the main vent has flowed underground for approximately 17 years, meaning that efforts to reduce nitrate intrusions in the springs head will not have any impact for 17 years.

The spring is one of the few sites that is home to the Georgia blind salamander; Shangri-La Spring (100 yards downstream is another.

Personal Impressions

As noted in the essay, this spring is JF's favorite place for swimmingin the Florida Big Bend.  The spring is heavily and increasingly polluted,however, and measures to reduce the proliferation of exotic plants havehad deadly side effects on native fauna.  To save the spring fromfurther degredation and the possibility that it would eventually have tobe closed to swimming and fishing, the state and county must work togetherto promote the adoption of best management practices by nearby farms anda golf course, and clean-up efforts in sinkholes that feed the spring. The local community is beginning to take notice that its longtime swimminghole is in trouble and to take efforts to protect it.

An Essay on Marianna Blue Spring

Note:  this essay was written when the springstill had its dive tower.

Where is the best place to swim in the  Big Bend? Grayton?  Destin?  Wakulla Springs?  St. Andrews? St. George?  Nope.  For me, none of these places compares toBlue Springs Park in Marianna.  Located an hour north of Panama Cityand 75 minutes west of Tallahassee, Marianna Blue Springs has it all, plus non-stop country music as an added bonus.

The springs have been a swimmin' hole for generationsof Jackson Countians.  Originally, the spring flows formed a narrowrun that joined the Chipola River just below where U.S. 90 now runs throughMarianna.  Years ago, the run was dammed, creating Merritt's MillPond which is 4.4 miles long and about 200 yards across.  The pondis popular with anglers, and there are fish camps and a campground on the west bank.

But it is the swimming that places the spring a cut above.A large circular pool 150 feet across lies in a natural depression and forms the headwaters.  A rock and sandbag retaining wall frames the pool and prevents erosion.  The water averages a few feet deep andis absolutely transparent. Its source is a first-magnitude spring that flows powerfully from a large-mouth cave directly under the diving platform. Water over the cave is a very deep and enticing blue.

Scuba is not allowed without special permission, but determined snorkelers can explore the cave entrance and glimpse a cold, dark, underwaterworld.  Getting into the cave takes a bit of effort.  One must fight the strong outflow from the cave, be able to hold a breath for aminute or so, and time the dive so as not to be squashed by cannonballersfrom the platform above.  A minivan could easily drive into the cave entrance, which is populated by large fish that scurry into the cave recesses when approached.

Watching from the platform, I marveled at a boy who spent three minutes in the cave.  Coming up, he explained there was an air pocket stocked by skin-divers with air-filled milk jugs.  Sticking one's head into the bucket-sized pocket of stale air is much more unnerving than the cave itself. Light and sound are distorted in the small space,and you get less air with each breath.

The swim area has free tubes, large and small slides,and a floating island in the middle.  As is typical for a north Florida spring, the water temperature is about 68 degrees, and many who swim outto the floating island are loath to return to the water after warming up.

A concession stand offers snacks and ping-pong balls touse on two nearby crumbling tables.  There is a volleyball area, and picnic tables and grills provide platforms for fun, food, and generally hanging out all day long. The structures on the site have been there atleast 30 years, and the whole place has a very old-timey feel about it. The park is ideal for kids of all ages, from toddlers who splash in the shallows to elementary schoolers searching for crawdads and daring eacho ther to jump from the platform to teens scoping each other out and trying to make the biggest splash.

A fence keeps boats out of the swim area, and if you havea canoe you can explore the pond.  Four other springs lie within afive-minute paddle of the main spring.  The nearest is the best. Aptly named Shangri-La, it is a strikingly beautiful spring that issuesfrom a shallow crevice at the base of a 30-foot limestone bluff. The peaceful translucent flow soothes every sense, and a trail to the bluffabove offers a panoramic view.

A little further down are Indian Washtub and Twin Cave springs. The latter lies among a scenic watery grove of cypress. The park costs just $1.50 per person, but it is only open from Memorial Day to LaborDay.  Our summer is not complete without a visit every year; unwinding at this simple and lovely spring has become an annual family pilgrimage.
