The Catawba River feeds Lake Wylie and continues to the Santee River, ultimately reaching the Atlantic Ocean. This watershed supports diverse aquatic life, including fish species such as striped bass and catfish, and provides drinking water for millions. The plant's operations are crucial for preventing nutrient pollution and protecting downstream habitats.
