The Grogan River (Kali Grogol) is a small river in the western part of the Special Capital Region of Jakarta, Indonesia. The lower portions of the original river have been channelized with levees built along its banks, but flooding remains a real concern. Illegal buildings built along its banks were removed in 2014, and fifty-eight village families were provided with replacement housing, but most of them could not be accommodated.
CourseEdit
The Grogol River arises around 06°33′39″S 106°47′26″E in Desa Kedungbadak and runs north between the Krukut River to the east and the Pasanggrahan River to the west, further north the Sekretaris River (Secretaris River) arises to the west. The Grogol passes through Desa Sukadamai and Desa Kencana. After crossing Jakarta Outer Ringroad (Jalan Tol Lingkar Luar Jakarta) it follows parallel to and just east of Route 12. At 06°15′41″S 106°47′07″E there is an overflow channel that goes west to the Pasanggrahan River. The Grogol continues north through Senayan City and just west of Gelora Bung Karno Stadium. It serves to drain the Palmerah Urban Village. Beginning at Bank Danamon Central Park it parallels Route 1 until 06°10′02″S 106°47′16″E where an overflow channel heads due west to join the Sekretaris River, while the channelized river continues beside Route 1 and flows into the Krucut River at 06°08′10″S 106°47′07″E.
