[1] The lower portions of the original river have been channelized and directed into the eastern flood canal, "Banjir Kanal Timur", which continues to flow to the Java Sea in the district of Marunda, Cilincing, North Jakarta.

[7] Research by Pieter J Kunu and H Lelolterry of Pattimura University, Ambon, showed that the development of the city changed 85% of land in Jakarta to be waterproof, unable to absorb surface water, and resulted in regular floods.

[7] The flow of the Cakung, Buaran, Jati Kramat, Sunter, and Cipinang rivers was cut to drain into the canal, thereby reducing the occurrence of floods.

[8] Currently, the old river flowing to Banjir Kanal Timur has a function as drainage from industrial and household waste.

[8][9] Cakung River has a length of 39.59 kilometres (24.60 mi), with a watershed area (Indonesian: Daerah Aliran Sungai) of 154.78 km².
