The courses of the rivers are greatly influenced by extensive ranges of hills, scarps & mountains, two of which meet at the most southerly point of the Volta Lake where the Akosombo Dam is situated, from which:
The Ghana-Togo mountain range extends to the north-north-east, crossing the Togo border east of Hohoe.
The Kwahu Plateau extends north-west, becoming the Mampong Scarp north of Kumasi, and progressively less dramatically reaching Côte d'Ivoire border west of Sunyani.
The Akuapem Ridge stretches south-south-west to Pokuase, about 20km north-north-west of Accra.
