It is formed in southern Sampson County, approximately 15 mi. (24 km) south of Clinton, by confluence of Great Coharin and Six Run creeks. It flows SSE, receiving the South River approximately 30 mi (48 km) south of Clinton. It flows southeast through Pender County, past the Moores Creek National Battlefield, and joins the Cape Fear approximately 10 mi (16 km) northwest of Wilmington, near the broadening of the Cape Fear into a tidal estuary.
Elsewhere along the river, slight variations in elevation allow for changes in the forest from fl gum and tupelo gum in lower areas, to water hickory, American elm, and some oak species on the ridges.
In recognition of the fact that the BlackRiver is one of the cleanest, high-quality waterways in NorthCarolina, the state designated the river an Outstanding Resource Water in 1994.
The BlackRiver is a treat to canoe throughout the seasons.
