Following the Civil War the farming, mining, and timber industries were re-established in Beaufort County and the lowcountry. This activity meant the waterways around Daufuskie, with its critical position between Port Royal and Savannah, became very busy. Navigation aids became necessary to support the increased volume of shipping. In 1873 the Haig Point Range Lights were constructed on the island's northern end. This was followed by the Bloody Point Range Lights in 1883 built to assist ships approaching the Savannah River entrance.
