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] References1. ^{{cite web |url=http://www.scsembenelli.com/BROCHURE/JIB.pdf |title=Jibiya Dam |publisher=Sembenelli Consulting |accessdate=2010-05-21 |deadurl=yes |archiveurl=https://web.archive.org/web/20110716022813/http://www.scsembenelli.com/BROCHURE/JIB.pdf |archivedate=2011-07-16 |df= }} {{Dams in Nigeria}}2. ^{{cite book |page=419ff |title=Geotextiles, Geomembranes and Related Products: Canals, reservoirs and dams. |editor=G.
