The swamp not only sends water south …
It also percolates water down into the aquifers below.
The Pinecrest chain of hammocks forms a line in the swamp below which two aquifers take form: to the east is the Biscayne Aquifer, the sole source of drinking water for Miami, and on the other side is the Tamiami Formation where, farther to the west, it’s tapped by west coast lying towns of Naples and Ft Myers. Ground water is Florida’s primary source of drinking water peninsula wide.
The video was filmed in winter when the cypress were still bare.
