The Yobe River, also known as the Komadougou Yobe also spelt Komadugu Yobe River or the Komadougou-Yobe (French: Komadougou Yobé), is a river in West Africa that flows into Lake Chad through Nigeria and Niger. Its tributaries include the Hadejia River, the Jama'are River, and the Komadugu Gana River. The river forms a small part of the international border between Niger and Nigeria with 95 miles (150 km) and flows a total of 200 miles (320 km) There are concerns about changes in the river flow, economy and ecology due to upstream dams, the largest at present being the Tiga Dam in Kano State, with plans being discussed for the Kafin Zaki Dam in Bauchi State. The River Yobe provides a means of subsistence for hundreds of thousands of people who work in a variety of commercial and agricultural endeavours along its almost 200 km length in the state's northern region, which spans seven local government areas (LGAs) from Nguru to Yunusari. Notable towns near the river include Gashua, Geidam, and Damasak in Nigeria, and Diffa in Niger.
