While the L-28 gets lumped as modern water management feat.
|This map shows a chronological history of when various canals and levees were built on the eastern edge of the Big Cypress Swamp|
Thus it is a reminder to look at this map.
The L-28 is practically a contemporary of the Trail; the modern day, not so much.
But Trail doesn't block flow into the Big Cypress,
It's the L-28 Levee that's doing that.
The best way to get water "into the heart" of the Big Cypress is at its northernmost reach.
Or in other words, a "modern" levee would take the Tieback out.
