What river system feeds into the Volta Lake, created by the Akosombo Dam?

The river system that feeds into the Volta Lake, which was formed by the Akosombo Dam, primarily consists of the Black Volta and White Volta rivers. These two rivers converge to create the Volta River, which is the main water source for Volta Lake. The Akosombo Dam was built on the Volta River to generate hydroelectric power, and the resulting lake serves as a reservoir.

The Black Volta originates from Burkina Faso and flows southward, while the White Volta also begins in Burkina Faso but flows southeast. Their convergence at the dam site is crucial for the functionality of the dam, and they significantly contribute to the lake's water levels.

In contrast, the other river systems listed do not have any hydrological connection to Volta Lake. The Congo River System is a major river that flows through Central Africa but does not connect to the Volta. Similarly, the Zambezi and Limpopo river systems are located farther south on the continent, with no influence on or relation to the Volta Lake. Thus, understanding the geographic and hydrological relationships leads to the recognition that the Black Volta and White Volta are the correct answer.
