Mahakam

The Mahakam flows from the mountains of central Borneo eastward to the Makassar Strait. Along its middle course, lakes, marshes and tributaries spread across a wide floodplain, their waters rising and falling with the river. Fish move between the river and its lakes, while boats connect communities along its banks. Farther downstream, the river passes the former seats of the rulers of Kutai before dividing into the channels of its delta.
