The Green Swamp is recognized by the state of Florida for its ecological and hydrological importance. There are several unique characteristics of the area. The Green Swamp can store surface water and slow the flow of floodwaters while sustaining rivers and streams. Its relatively high elevation, together with a shallow depth to the aquifer, keeps water levels high. The water table for much of the year stands above the potentiometric surface of the Floridan aquifer, providing…
