Now Brooklyn Lake is unique in the fact it is fed by a surface flow. Most of our lakes in this region are landlocked lakes and do not have a creek or stream to supply them with water. They are some times referred to as seepage lakes, which are fed by seepage through the ground. This seepage comes from what is known as the Surficial Aquifer. The Surficial Aquifer gets its’ water from the water table and from the pressurized waters from the Floridan Aquifer and the Intermediate Aquifer.
So what is the deal with all the different aquifers?
The lake region surrounding Keystone Heights area is somewhat unique in the fact that we have 3 types of aquifers. Most people are aware of the Floridan Aquifer, which lies several hundred feet below the surface of the ground. The Floridan Aquifer is very large and covers nearly the entire state of Florida, parts of Georgia and South Carolina. It also contains billions and billions of gallons of water. The Intermediate Aquifer is an aquifer system right above the Floridan aquifer, which works in conjunction with the Floridan Aquifer. The Intermediate Aquifer gets its’ water from the pressurized waters pushing up through the soil from the Floridan Aquifer. The Surficial Aquifer is the aquifer system right above the Intermediate Aquifer and is the one closest to the surface, hence its’ name the Surficial Aquifer. This is the aquifer most of our lakes get their water from. Some of our lakes are fed by springs from this aquifer. Those springs are referred to as surficial springs. Here again this aquifer works in conjunction with the other two aquifers. The lakes in our region here in Keystone Heights, are very unique in the fact that they serve as a recharge to the Floridan Aquifer. (cont'd)
