Subsequently, by Thursday (30/11/2023) at 5:00 AM local time, the flood gates at the Katulampa dam had escalated to Alert 3 status, with the water level reaching 200 cm. According to BPBD DKI Jakarta, there’s a foreseeable risk of flooding in the immediate vicinity of the dam for an unspecified duration in the coming hours.
List of Jakarta Flood Affected Area
The overflow from the Katulampa Dam is anticipated to impact various areas, accompanied by specific information regarding the flood water levels:
- Pejaten Timur: 30-150cm
- Rawajati: 70-80 cm
- Bale Kambang: 150 cm
- Cawang: 30-200cm
- Cililitan: 50-100 cm
- Bidara Cina: 50-150 cm
- Kampung Melayu: 30-150 cm
Additionally, several major roads encountered flooding, including Kemang Highway and Lenteng Agung Highway, where water levels reached up to 20 cm.
The intense rainfall in Jakarta exacerbated the rising water levels. To prepare, the DKI Jakarta government initiated dredging of the Ciliwung River in mid-November 203. The Meteorology, Climatology, and Geophysics Agency (BMKG) forecasts heavy rainfall for Jakarta and its environs from January to February 2024.
About Katulampa Dam
Situated in Bogor, the Katulampa Dam has been a vital water structure since its construction in 1911, serving as a critical indicator for potential floods in the Jakarta region. Geographically, Jakarta sits at a lower elevation compared to Bogor, resulting in water flowing downstream (from Bogor to Jakarta).
Any deviation in the usual height limits observed at the Katulampa Dam signifies a significant risk of flooding in Jakarta. Typically, water levels surge as the rainy season commences. In 2023, the rainy season is expected to begin in late November and extend until February 2024.
