The summit of Mount Sumbing serves as the meeting point of the borders of three river basins, namely, the Progo basin on the eastern side of the mountain, the Serayu basin, and the Bogowonto basin on the western side of the mountain. The Progo River Basin covers more than 50% of the Mount Sumbing complex. Each of these river basins flows towards the southern coast of Java, eventually emptying into the Indian Ocean.^[3]
