Which rivers flow through mainland Equatorial Guinea?

The mainland portion of Equatorial Guinea, known as Río Muni, features several significant rivers that shape its geography:1

• Mbini River: Also known as the Benito River, it flows generally from east to west through the central part of Río Muni.1
• Campo River: Known as the Ntem in French-speaking Africa, this river marks a portion of the border with Cameroon to the north.1
• Utamboni River: This river flows through the southern region of the mainland.1
• Kié River: This river follows the meandering course of the eastern border with Gabon.1

Additionally, the Muni is an estuary located in the southwest that serves as the outlet for various rivers from Gabon and southern Equatorial Guinea. These rivers are utilized for limited hydroelectric power generation and waterpower at some lumbering sites.1
