A river located west of Mount Slamet, Central Java. Throughout the year the water that flows is always cloudy or not clear, this is due to the flow of water that carries a lot of sand, gravel, mud and stone materials from cold land used by the eruption of Mount Slamet. Even though it is one of the rivers that causes cold lava flows, this river is not so well known, compared to Kali Gendol in Yogyakarta. Gendol times are often discussed, especially when Mount Merapi is erupting.
