As a result of land subsidence due to oxidation of the farmed peat.
|The Lake used to naturally flow south. |
Now it's stuck behind a levee except
for a few gates.
That in part explains why the levee is so tall:
Forty two feet above sea level and 143 miles around.
Subsidence also explains why south Florida uses water pumps.
Water no longer gravity drains like it once did.
Subsidence is hard to imagine, let alone see.
But there's nothing subtle about its impact on the Everglades.
