Yes, water has a mind of its own,
But what it’s thinking at any one moment is easy to guess:
|Looking downstream (west)|
from the canal’s perspective
The tricky part is trying to figure out which direction that means.
What makes that so hard you may ask? One, the swamp is very flat by nature to begin with and two, there are new hills (roadbeds and levees) and valley (canals) that, from the perspective of water, have changed the lay of the land.
|Looking downstream (south)|
from the strand’s perspective
That leaves us with a modern-day case of conflicted water:
Instead of going straight south (above), some of it turns right (west) into the Tamiami Canal.
The solution is to sequentially add plugs along the canal’s entire length.
