The Alau Dam was situated in the Alau community of Konduga local government area of Borno State in the Northeast region of Nigeria, constructed in 1984–1986. It impounds a major reservoir on the Ngadda River, one of the tributaries of the Lake Chad. In 2024, the dam collapsed, causing catastrophic flooding in Borno State and killing over 150 people, with at least 419,000 people displaced.
