The
Goulbi de Maradi is a river in south central
Niger and north central
Nigeria. Between its source near
Katsina in Nigeria, and its end in the
Rima River, the Goulbi de Maradi never flows more than from the Niger–Nigeria border. Though important for agriculture and pastoralism, and flowing through the Niger cities of
Maradi,
Guidan Roumdji, and
Madarounfa, the Goulbi de Maradi is a seasonal river and flows only during the rainy season.
