The Ntem is a river in central Africa .
course
It has its sources in Gabon , in the Minkébé National Park in the Woleu-Ntem province , at about 600 meters, in a narrow network of small rivers. From there it flows in a west - northwest direction, towards the border with Cameroon, where it takes in the Kom . From there it forms the border between the two states over a length of about 30 kilometers. In its further course in a westerly direction it flows through the southwest of Cameroon until it is dammed about 100 kilometers before the confluence with the Memve'ele Reservoir , a heavily branched lake with many islands that is used for energy generation.
After the reservoir, it flows in a south-westerly direction, along the Campo Ma'an National Park , towards the border with Equatorial Guinea , which it reaches about 50 kilometers from the mouth. There the river divides into a main arm and the northern branch, the Bangola, and forms with it the island "Ila Dipikar". Shortly before the estuary, the Ntem, which is usually referred to as the Rio Campo, joins the Bangola again. In the south it borders on the mouth of the Rio Campo nature reserve , and in the north on the Campo Ma'an National Park.
Hydrometry
The flow rate of the river was measured in m³ / s on the border with Gabon in Ngoazik, at about 1/2 of the catchment area
Flora and fauna
The Ntem flows through or borders on various nature reserves ( Campo Ma'an National Park , Rio Campo Nature Reserve , Minkébé National Park ). In addition, large areas of its catchment area are in sparsely populated areas. The endemic Boulengeromyrus knoepffleri lives in the river.
