Normally, the surf can be heard faintly throughout our family's house on the coast of Georgia. This morning, the volume seems to have increased a few decibels. As I look east, toward the sunrise, the ocean appears to be closer to the house than normal.
This higher-than-normal tide reminds me of a conversation I overheard the day before.
My husband, son and I had decided to brave the overcast and rainy morning and joined a boat tour of the marsh surrounding St. Simons Island. Also on the boat tour was an extended family from Fort Worth, Texas.
At the time of the tour, about two hours before low tide, the high-water marks were clearly visible above the water. These marks led to a discussion about the timing of the tides and their impact on fishing in the area. One of the men from Fort Worth was discussing with the captain the upcoming "flood tide," trying to determine the timing and impact of the upcoming higher-than-normal morning high tide.
The reference to a "flood tide" was one I had never heard before. As I understood their conversation, a flood tide occurs when the high tide is higher than normal, creating a flood in low-lying areas.
Of course, where there is water, there is also the possibility of fish.
This flooding allows redfish to swim into areas that are normally dry, providing them with access to fiddler crabs, which are normally not accessible to them. This opportunity for the fish (access to fiddler crabs) ends up being an opportunity for people who fish (a higher-than-normal concentration of redfish).
Flood tides occur once a month, with the full moon. If you know when they are going to occur, then you can take advantage of the opportunity and, potentially, catch more fish than normal.
If you are not aware of the flood tide, the opportunity can become a hazard. The boats can travel into the marsh with the tide, but when it recedes, those aboard can be left high and dry, stuck in an area that will not see tidewater again for another month.
Once this occurs, they are left with the option of dragging the boat through the mud, back into the water, or leaving the boat until the next flood tide unlodges it.
