Florida, South Carolina and parts of Georgia saw near-record rainfall in the last six months of 2012 and throughout 2013.
Researchers have blamed the 2012 decline of the oyster population in the Apalachicola Bay on persistent droughts from 2009 through 2012 throughout the Apalachicola-Chattahoochee-Flint basin. Oyster harvest landings declined 60 percent over the last year, resulting in a 44 percent drop in revenue.
They’ve had an unusual amount of rainfall in the drainage basin. So it certainly will be beneficial to the recovery of the estuaries and the oyster fishery.
The rebound really started in December 2012 as North America came out of a La Nina weather pattern that cast dry, cooler air over the Southeast and continued through the past summer, at the headwaters of the basin, which drains down to the Apalachicola Bay, had more than 101 inches of rain last year.
Water flows through the Jim Woodruff Dam into the Apalachicola River have been rising dramatically, even prompting flood warnings from the National Weather Service during the first week of this year.
The rising freshwater flows are a promising sign, but the oyster industry still needs more efforts to recover. The re-shelling of more than 1,000 acres of the bay floor over the next five years is needed to rebuild oyster bars destroyed by hurricanes and predators that thrive when freshwater is lacking and saline levels soar.
Illegal harvesting also has strained the bay’s oyster population. An increasing number of undersized oysters have been harvested, and in some cases 90 percent of the catch was undersized.
