Hulu Mendawai
Hulu Mendawai is the upper country of the Mendawai, also known as the Katingan River, in southern Borneo. The river rises in the Schwaner Mountains and flows south through the forested interior toward the Java Sea. Its basin lies beside that of the Mentaya, another great river draining the island's central highlands. Together these waterways cross a broad landscape of tropical forest and lowland river country before reaching the coast.
