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.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.
