The Kainji Dam as we know, is a dam across the Niger River in Niger State and the first dam project in Nigeria.
Construction of the dam was carried out by Impregilo (a consortium of Italian Civil Engineering Contractors) to designs by Joint Consultants, Balfour Beatty and Nedeco, and began in 1964 to be completed in 1968.
The total cost was estimated at US$209 million which is equivalent to about US$1.4 billion today.
The dam was designed to have a generating capacity of 960 megawatts; however, only 8 of its 12 turbines have been installed, reducing the capacity to 760 megawatts.
The dam generates electricity for some large cities in Nigeria while some of the electricity is sold to neighbouring countries.
Below are some of the construction pictures I could get and some recent pictures as well.
