Saltwater invasion

Here's a hydrograph comparing three stations along the Tamiami Trail ...

In the area that we observed the unusual "wet season" like flooding in the coastal marsh south of Tamiami Trail in the Ten Thousand Islands area.

About the chart above: Notice how the two inland stations -- BCA8 (Turner River) and BCA7 (Turner River Canal) -- have steadily dropped throughout the dry season -- whereas the station at Bridge 71 (red dot and line) had an unusual rise during April that does not seem to correlate with any significant rainfall during the same period.

As for the source of the water:

If the strong south wind didn't already make it abundantly clear ...


A fish kill of talapia in in a pool at the southern end of Birdon Road left little doubt.

They are freshwater fish and cannot tolerate salt.
