Where does the Niger River form an inland delta in Mali?

In Mali, the Niger River forms an inland delta—often referred to as the internal or central delta—beginning at the town of Mopti, where the river is joined by its largest right-bank tributary, the Bani River.12

In this region, the land is exceptionally flat and the river's gradient is almost nonexistent, causing the Niger to break into a complex network of lakes, creeks, and backwaters. During periods of high water, these features often merge into a general inundation. This labyrinthine system continues northward until it reaches Kabara, the port of Timbuktu, where the river turns eastward. The rich alluvial soils and periodic flooding in this central delta make the area a vital agricultural region for Mali.12
