"Gate-driven" watershed?

The Big Cypress is commonly called rain-driven,

But here's look at a gate sending water into the swamp.

Water is flowing under the levee
through two submerged culverts

As seen at the S-344 about 9 miles north of the Tamiami Trail,

Looking east across the L-28 into Water Conservation Area 3A.


Also shown are two emergency pumps which, as of two weeks ago, were shut off.
