Yes, the levees are earthen bulwarks against the Everglades (which is actually a wide, shallow, slow moving river and not a swamp - see
The Everglades: River of Grass by Marjory Stoneman Douglas - yes the same Marjory Stoneman Douglas that the infamous high school in Parkland is named after - the high school is just east of the levees, maybe 20 miles south of the picture below). In the picture below, looking north, the levee is on the east, to the west of the levee is the canal where the sand to build the levee was excavated from, and to the west of the canal is the Everglades, which is NOT dry land, it is actually water, a foot or two deep, with vegetation growing through it. From the air, you can see the sky reflected from the water through the vegetation.
The levees and canals are simultaneously what make the large population of south Florida possible but are instruments of large scale ecological disaster for the Everglades. The Everglades watershed starts south of Orlando near Kissimmee and the Everglades proper starts south of Lake Okeechobee and flows to the Florida Bay at the south end of Florida - north of the Florida Keys.
The picture below was take just south of Wellington, FL which is maybe 15 miles to the southwest of the Donald in Mar-a-Lago which is basically due east of the southern tip of Lake Okeechobee. This is the easternmost reach of the Everglades today.
Without the levees, south Florida would seasonally be under water. The levees and canals are used to divert the water east and west to prevent this seasonal flooding, depriving the southern Everglades of its natural water supply. The levee and canal system was started about 100 years ago and efforts are underway to try and mitigate some of the damage that has been done. The Everglades is a unique ecology that exists no where else on earth. There are hundreds of miles of levees and I am just stating to explore them - basically the only place to ride in south Florida where you can get away from the cars.

Lovely photos, of a landscape so very different from others I've enjoyed. Thanks for sharing.
Pray, explain "levees." I anticipate that these are earthwork bulwarks against river or sea; please explain, and tell us where this is.
