Abstract This paper examines the freshwater pond and dam system identified on the Xena map of Oak Island, Nova Scotia, and argues that it represents a deliberately engineered logistical feature supporting sustained animal-powered operations. By analyzing hydrology, terrain, known road systems, and the spatial relationship between animal pens, blacksmithing activity, and industrial features, this study proposes that the pond was part of an integrated French naval support system rather than an incidental or natural formation. The conclusions drawn align with known 17th–18th century European military logistics and shipyard practices
