Blackwater rivers of South Carolina
- "Four blackwater rivers—the Waccamaw, Pee Dee, Black, and Sampit—feed into Winyah Bay, an estuary in eastern South Carolina. All of them flow through swamps, wetlands, and forests that are rich with decaying vegetation and other organic matter. The dead leaves and debris stain the rivers and wetlands a transparent brown color as several natural chemical substances found in plants—tannin, phenol, and humic acid—seep into the water... After heavy rains, stained floodwaters can get flushed out of swamps and wetlands into the estuary and ocean."- Excerpt from NASA Earth Observatory
