$3 to get in park

no pets in park.... : (

HANDICAP ACCESSIBLE : )

so beautiful here. float down or just walk by it. either way it'll take your breath away.

a little about springs:

Aquifers are underground rocks that hold water. In Florida, three aquifers are used for water supply: the Floridan aquifer, the intermediate aquifer and the surficial aquifer. In some parts of the state the intermediate aquifer is between the surficial aquifer and the Floridan aquifer. In northwest Florida, the surficial aquifer is called the sand and gravel aquifer, and in southeast Florida it is called the Biscayne aquifer.

The Floridan aquifer has been called Florida’s rain barrel (Parker 1951) and is one of the most productive aquifers in the world. Each day Floridians use about 2.5 billion gallons of water from the Floridan aquifer. It underlies 250,000 square kilometers (100,000 square miles) in southern Alabama, southeastern Georgia, southern South Carolina and all of Florida. Over most of Florida, the Floridan aquifer is covered by sand, clay or limestone that ranges in thickness from a few feet in parts of west-central and north-central Florida to hundreds of feet in southeastern Georgia, northeastern Florida, southeastern Florida and the westernmost Panhandle.

Within the aquifer, water may travel quickly or very slowly. In parts of the aquifer with caves and large conduits, water may travel several miles in only a few hours. Where water-filled spaces are small and underground routes convoluted, it may take days, weeks or even years for water to travel the same distance. In the past several decades, increased pumping of ground water has lowered water levels in the Floridan aquifer in several places in Florida and Georgia, including the Panhandle, northeastern and southwestern Florida, and southeastern and coastal Georgia (Berndt et al. 1998).

Water is replaced in the Floridan aquifer by rainfall that soaks into the ground. This is referred to as recharge. Recharge does not occur everywhere. In some places (mostly along the coasts and south of Lake Okeechobee) water flows out of, rather than into, the aquifer. This is referred to as discharge. In other areas, thick clay covers the aquifer and slows or stops the downward flow of water. Areas of high recharge only occur in about 15 percent of the state and include the well drained sand ridges of central and west central Florida. Sand is porous, which means water can easily flow through it.

Limiting intensive development in high recharge areas is critical for maintaining water supplies: water cannot soak through pavement.

In some parts of Florida, the Floridan aquifer is not a suitable or drinkable source of fresh water. In some places, it is too far below the surface; in other places, the water is salty. The surficial sand and gravel aquifer is the major source of fresh water in Escambia and Okaloosa counties in northwest Florida, and the surficial Biscayne aquifer is the major source of fresh water in Dade and Broward counties in southeast Florida. This aquifer is an important source of fresh water in Sarasota, Charlotte and Glades counties. The remainder of the state uses the Floridan aquifer as its main source of drinking water.

A spring may be the result of karst topography where surface water has infiltrated the Earth's surface (recharge area), becoming part of the area groundwater. The groundwater then travels through a network of cracks and fissures—openings ranging from intergranular spaces to large caves. The water eventually emerges from below the surface, in the form of a karst spring.

The forcing of the spring to the surface can be the result of a confined aquifer in which the recharge area of the spring water table rests at a higher elevation than that of the outlet. Spring water forced to the surface by elevated sources are artesian wells. This is possible even if the outlet is in the form of a 300-foot-deep (91 m) cave. In this case the cave is used like a hose by the higher elevated recharge area of groundwater to exit through the lower elevation opening.

Non-artesian springs may simply flow from a higher elevation through the earth to a lower elevation and exit in the form of a spring, using the ground like a drainage pipe.

Still other springs are the result of pressure from an underground source in the earth, in the form of volcanic activity. The result can be water at elevated temperature such as a hot spring.

The action of the groundwater continually dissolves permeable bedrock such as limestone and dolomite creating vast cave systems.

Types of spring outlets
Seepage or filtration spring. The term seep refers to springs with small flow rates in which the source water has filtered into permeable earth.
Fracture springs, discharge from faults, joints, or fissures in the earth, in which springs have followed a natural course of voids or weaknesses in the bedrock.
Tubular springs are essentially water dissolved and created underground channels, basically cave systems.

ok heres how to get credit

1. what's the avg water temp.?

2. whats the avg water flow per min. ?

3. post a pic if ya want to
