The Akosombo Dam Spillage Flood is a riverine flood that occurred in the south-eastern part of Ghana. [1] [2] This is due to a controlled spillage of the Akosombo Dam and the Kpong Dam by the Volta River Authority to address rising water levels. [3]
According to the BBC News, the cause of the flood was the heavy rainfall experienced in Ghana during 2023 leading to an increased volume of water in the two dams which in turn led to the Volta River Authority's initiation of controlled spillage of the dam in September 2023. [4]
The Akosombo Dam has a 150 billion cubic meters storage capacity with a maximum operating level of 276 feet. [5] Due to the effects of climate change, Ghana has been experiencing rising levels of rainfall, causing the water levels to rise beyond the maximum operation capacity. [6] Without the spillage exercise, this could lead to dam failure. [7] The spillage exercise started on 15 September 2023, at 183,000 cfs/day. This was increased on 9 October 2023 due to continued rise of the water level. [1]
The spillage led to the displacement of 8,000 people in 8 communities along the Volta River downstream, with Mepe being the most affected. [4] The numbers have since increased to 31,000 [8] as of 19 October 2023.
Communities impacted by the flood includes; the districts of North, Central, and South Tongu in the Volta Region, as well as the Asuogyaman District in the Eastern Region. Large portions of Tefle, Wume, Sokpoe, and other riverbank communities have also been affected by the floods, and at least 500 people are now without a place to live. Other localities, such as Alikekope, Agorme, and Agbave, have completely disappeared. [9]

The Volta River is the main river system in the West African country of Ghana. It flows south into Ghana from the Bobo-Dioulasso highlands of Burkina Faso. The main parts of the river are the Black Volta, the White Volta, and the Red Volta. In the northwest, the Black Volta forms the international borders between the Ivory Coast, Ghana, and Burkina Faso. The Volta flows southward along the Akwapim-Togoland highlands, and it empties into the Atlantic Ocean at the Gulf of Guinea at Ada Foah. It has a smaller tributary river, the Oti, which enters Ghana from Togo in the east. The Volta River has been dammed at Akosombo for the purpose of generating hydroelectricity. The reservoir named Lake Volta stretches from Akosombo Dam in the south to the northern part of the country, and is the largest man-made reservoir by area in the world.
The Akosombo Dam, also known as the Volta Dam, is a hydroelectric dam on the Volta River in southeastern Ghana in the Akosombo gorge and part of the Volta River Authority. The construction of the dam flooded part of the Volta River Basin and led to the subsequent creation of Lake Volta. Lake Volta is the largest man-made lake in the world by surface area. It covers 8,502 square kilometres (3,283 sq mi), which is 3.6% of Ghana's land area. With a volume of 148 cubic kilometers, Lake Volta is the world's third largest man-made lake by volume; the largest being Lake Kariba which contains 185 cubic kilometers of water.
Lake Volta, the largest artificial reservoir in the world based on surface area, is contained behind the Akosombo Dam which generates a substantial amount of Ghana's electricity. It is completely within the country of Ghana and has a surface area of 8,502 square kilometres. It extends from Akosombo in the south to the northern part of the country.
The Eastern Region is located in the Eastern part of Ghana and is one of the sixteen administrative regions of Ghana. Eastern region is bordered to the east by the Lake Volta, to the north by Bono East Region and Ashanti region, to the west by Ashanti region, to the south by Central region and Greater Accra Region. Akans are the dominant inhabitants and natives of Eastern region and Akan, Ewe, Krobo, Hausa and English are the main spoken languages. The capital town of Eastern Region is Koforidua.The Eastern region is the location of the Akosombo dam and the economy of the Eastern region is dominated by its high-capacity electricity generation. Eastern region covers an area of 19,323 square kilometres, which is about 8.1% of Ghana's total landform.

The Bui Dam is a 400-megawatt (540,000 hp) hydroelectric project in Ghana. It is built on the Black Volta river at the Bui Gorge, at the southern end of Bui National Park. The project was a collaboration between the government of Ghana and Sino Hydro, a Chinese construction company. Construction on the main dam began in December 2009. Its first generator was commissioned on 3 May 2013, and the dam was inaugurated in December of the same year.
The Kpong Dam, also known as the Akuse Dam, is a hydroelectric power generating dam on the lower Volta River near Akuse in Ghana. It is owned and operated by Volta River Authority. It was constructed between 1977 and 1982. Its power station has a capacity of 148 megawatts (198,000 hp) with all four units running, though the total nameplate capacity is 160 megawatts (210,000 hp).
The 2009 West Africa floods are a natural disaster that began in June 2009 as a consequence of exceptionally heavy seasonal rainfall in large areas of West Africa. Several rivers, including the Pendjari, Niger, Volta and Senegal rivers, broke their banks, causing destruction of houses, bridges, roads and crops. The floods are reported to have affected 940,000 people across 12 countries, including Burkina Faso, Benin, Ghana, Niger, Senegal, Guinea, and caused the deaths of at least 193 people. In Burkina Faso, one of the most affected countries, 150,000 people fled their homes, mostly in the capital Ouagadougou where rainfall in one day was equal to 25% of normal annual rainfall for the whole country.
