Most of Liberia's rivers flow in roughly parallel courses from the interior plateau to the ocean. Several of them, including the Lofa, the St. Paul, and the St. John, rise in the Guinea Highlands north of the border with Guinea.

Liberia's rivers
03/08/2019
The Mano and Morro Rivers to the west form parts of the border with Sierra Leone. To the east, the Cavalla River forms the entire border with Côte d'Ivoire. The St. Paul River forms part of the border with Guinea. Rapids, waterfalls, and other barriers severely limit inland navigation.
Liberia's only sizable lake is Lake Fisherman (Lake Piso), which has an area of about 40 square miles.
