The Jibiya Dam is in Jibiya local government area of Katsina State in the north of Nigeria. It is an earth-fill structure with a geomembrane liner, with a height of 23.5 m and a total length of 3,660 m, and has a capacity of 142 million m3.The dam was designed in 1987 and completed in 1989, and was built to support irrigation and water supply.[1] The landscape at the dam site is sub-desertic except in the rainy season.The Gada river flows for only about four months each year, with a catchment area at Jibiya of over 400 km2.Due to the loose sandy nature of the surface soil, a flexible impervious liner was used that could adapt to settling or deformation of the embankment.[2]
An assessment of the dam in 2004 rated its condition "good" but noted that no instrument readings had been made since 1994 due to lack of training of the operators.[3] As of 2007, the dam was not being used for irrigation due to lack of fuel to run the pumps.[4] The Gada River flows from Nigeria into Niger and then back into Nigeria. In the past, it was dry for eight months of the year. There is now a regulated flow throughout the year, which has improved the water supply in Niger.[5]
