Ghana is well endowed with water resources.
The Volta River system basin, consisting of the Oti River, Daka River, Pru River, Sene River and Afram River as well as the White Volta and Black Volta rivers, covers 70% of Ghana's total land area.
Another 22% of Ghana is covered by the southwestern river system watershed comprising the Bia River, Tano River, Ankobra River and Pra River.
The coastal river system watershed, comprising the Ochi-Nawuka River, Ochi-Amissah River, Ayensu River, Densu River and Tordzie River, covers the remaining 8% of Ghana.

Furthermore, groundwater in Ghana is available in mesozoic and cenozoic sedimentary rocks and in sedimentary formations underlying the Volta Basin.
Lake Volta, with a surface of 8,500 km², is the Earth's largest artificial lake.
In all, the total actual renewable water resources are estimated to be 53.2 billion m³ per year.
