The Carolina Coastal Sampit Watershed (HUC 03040207) covers an area of approximately 1,200 square miles in South Carolina. The Sampit River is the main body of water in the watershed, which eventually flows into the Atlantic Ocean. The hydrology of the watershed is influenced by rainfall patterns, which are highest in the summer months. Snow is rare in this region. Surface water quality is impacted by agricultural and urban runoff, and there are concerns about nutrient pollution and harmful algal blooms in reservoirs. Climate trends in the area include increasing temperatures and sea level rise, which may lead to more frequent flooding events. Interesting climatic facts include the region's vulnerability to hurricanes and tropical storms, and the fact that the Sampit River is one of the few remaining wild and scenic rivers in the state.
