Location: The South Undeep is bordered by the Wold on the western shore, and the Brown Lands on the eastern shore. Using the scale on the Unfinished Tales inside cover map, the South Undeep is approximately 5 miles south of the North Undeep. See also the entry for Undeeps.
Description: "In later days Gondor built a bridge over the upper Limlight, and often occupied the narrow land between the lower Limlight and Anduin as part of its eastern fences, since the great loops of the Anduin (where it came down swiftly past Lórien and entered low flat lands before its descent again into the chasm of the Emyn Muil) had many shallows and wide shoals over which a determined and well-equipped enemy could force a crossing by rafts or pontoons, especially in the two westward bends, known as the North and South Undeeps."

Gondor had forts to watch the area, but were already unmanned in the days of Cirion:
"But during the Watchful Peace the forts along the Anduin, especially on the west shore of the Undeeps, had been unmanned and neglected."
