S-12s on the rise

Even with the S-12A and B gates still being closed,

Flow through the S-12s is still "above average" for early July.

Hydrograph showing discharge through the four S-12 structures from 2015 to present.  The dotted white line shows the long-term median and the blue line the recent few years.  The S-12s are closed each winter and spring per regulatory criteria.

The reason?

Answer: The record-rainy May filled up upstream Water Conservation 3A.

On the downstream side of S-333,
a companion structure to the S-12s that, instead of directly
sending water south into the Park, releases water east towards
the new bridges being built on the Tamiami Trail

As for when the S-12A and B will open, I suspect later this month.
