The Inner Niger Delta, also known as the Macina or Masina, [2] is the inland river delta of the Niger River. It is an area of fluvial wetlands, lakes and floodplains in the semi-arid Sahel area of central Mali , just south of the Sahara Desert .
Another example is the delta of the Tagus river in Portugal, although due to sedimentation this delta is now only very partially inverted, with the valley now mostly filled with sediment. It is still about 15 km (9.3 mi) wide and 25 km (15.5 mi) long, compared with the 2 km-wide (1.2 mi) exit into the sea, and forms a large lagoon with large ...
An unusual feature of the river is the Inner Niger Delta, which forms where its gradient suddenly decreases. [20] The result is a region of braided streams, marshes, and large lakes; the seasonal floods make the Delta extremely productive for both fishing and agriculture.

The effects of the dams on the flooding of the Inland Niger Delta downstream of Mopti are expected to be modest, [18] as the discharge of the Bani is only one third of that of the Niger: for the period 1952-2002 the average flow at Douna was 424 m 3 (15,000 cu ft)/s compared with 1,280 m 3 (45,000 cu ft)/s for the Niger at Koulikoro.
Below Lake Debo, the Niger valley is marked by a large number of lakes, which are lower than the river level. [11] As part of the central delta, the lake is the largest. As it is a part of the Niger River, its size varies with the fluctuation in the water level. [8] and maximum flood occurs in the river during November and December. [10]
The town sits on the floodplain between the Niger and Bani rivers at the southern end of the Inland Niger Delta. The town has an area of around 70 ha (170 acres) and during the annual floods becomes an island that is accessed by causeways. The Bani river is 5 km (3.1 mi) south of the town and is crossed by ferry.
In May, California banned commercial and recreational salmon fishing for a second straight year due to low numbers. Members of the Karuk and Yurok tribes continue small-scale subsistence fishing.
The Niger River valley, which dominates the topography of Mali, drained by the Niger River and its tributaries. Along its course, the central southern region is the narrowest and is known as the Inner Delta or the Inundation Zone of the Niger, formed of 38,000 square kilometres (15,000 sq mi) of flood-plains, along a river length of 570 kilometres (350 mi); these form its wetlands of great ...
