Parts of South Carolina got more than 20 inches of rain the first week of October 2015. That influx of freshwater in the rivers and marshes lowered salt levels and flushed fish downstream.

DNR has been monitoring and testing water and animals for more than 25 years. Associate Marine Scientist Steve Arnott said that data will provide important context for results, which he plans to unveil in the fall.
