Kelay
Kelay lies along a river of eastern Borneo, in the forested interior of the Berau country. The Kelay flows northeast to meet the Segah at Tanjung Redeb; together they form the Berau River, which reaches the sea through a network of channels. Tributaries enter both rivers from the surrounding forests, making the basin an extensive system of waterways linking the interior with the eastern coast of the island.
