How deep should the Everglades be ...

And for how long?

The graph above shows a comparison of median annual water depths across the Everglades, as calculated from 1993 to present.

Despite its flatness, the Everglades used to be able to assimilate and store more water. We tend not to think of sloughs as channels today, but prior to drainage they were deeper and had more definitive edges. That natural network of slough channels helped route the water south. Today, levees block the flow ... no place more so that southern 3A. That causes sloughs to fill in and waters to pool instead of feeding into downstream Big Cypress National Preserve, Everglades National Park and even adjacent Water Conservation Area 3B. Flows into the latter two are highly regulated because of their interconnectivity with the Biscayne Aquifer below and its inter-relation with urban east coast flooding.

Regulation schedules and infrastructure constraints rule the day.

Change in the Everglades rarely comes overnight.
