The Mayo Kébbi (also Mao Kebi or Kabia) is a river in Chad and Cameroon .
course
Its sources are on the border of Chad with Cameroon, on the northeastern flanks of the Adamaua highlands . On the upper reaches, the Mayo Kébbi flows through the Tikem and N'gara lakes and is connected to the Logone via the Fianga lake . The Mayo Kébbi receives a substantial proportion of its water masses from the Logone over a large flood plain. The river has a sharp separation of the upper and lower reaches, this is created by a series of rapids and two larger waterfalls, which overcome a total difference in height of 110 meters and are collectively called the Gauthiot waterfalls . The Kebi flows into the Benue about 14 km east of the town of Garoua in a wide delta .
The provinces of Mayo-Kebbi Ouest and Mayo-Kebbi Est in Chad, which it flows through, are named after him.
Hydrometry
The flow rate of the river was measured at the Cossi station in m³ / s
Mega Chad
The connection between Logone and Mayo Kébbi via the flood plain corresponds to the discharge from the historic mega-Lake Chad in its maximum extent more than 5000 years ago. Thus, the Mayo Kébbi establishes a connection to the now endorheic Chad Basin , which increased the Niger catchment system by 2.434 million km². This connection is probably the cause of the occurrence of African manatees in the tributaries of Lake Chad, which is cut off from the sea.
Protected areas
The flood plain of the Longone was placed by Chad under the title Plaines d'inondation du Logone et les dépressions Toupouri under the protection of the Ramsar Convention .
The lower reaches of the Mayo Kébbi watered the Trene Lake and léré lake that is part of the game reserve Binder Léré are and where a population of the rare African manatee lives.
