Akosombo Dam - Impacts

Impacts

The Akosombo Dam benefited some industrial and economic activities from the addition of lake transportation, increased fishing, new farming activities along the shoreline, and tourism. The power generated has provided for primary interests within Ghana, while also supplying power to the neighboring countries of Togo and Benin. Ghana’s industrial and economic expansion triggered a higher demand for power, beyond the Akosombo's power plant capabilities. By 1981, a smaller dam was built at the town of Kpong, downstream from Akosombo and further upgrades to Akosombo have become necessary for maintaining hydropower output. Initially, the dam’s power production capabilities greatly overreached the actual demand; while, the demand since the dam’s inception has resulted in the doubling of hydropower production. Increasing demands for power exceed what can be provided by the current infrastructure. Power demands, along with unforeseen environmental trends, have resulted in rolling blackouts and major power outages. An overall trend of lower lake levels has been observed, sometimes below the requirement for operation of the Akosombo Dam.
