History

The Mookervaart was originally constructed in 1678 to 1689 to draw one third the water flow from the Cisadane River, and link to the city canals of Batavia, to control the flood.
[ In 1732 Governor General Diederik Durven ordered the canal to be dug deeper to bring more water to the city, but this created stagnant pools that brought deathly illness, such as malaria, increasing the mortality.][R.J. Ross, Gerard J. Telkamp (eds). ''Colonial Cities: Essays on Urbanism in a Colonial Context''. Volume 5 of ''Comparative Studies in Overseas History'']
Springer Science & Business Media, 2012. Furthermore, the canal also swells very high during the rainy season, so a lock was built at the upper end of the river in 1770.[Stockdale, John Joseph. ''Sketches, Civil and Military, of the Island of Java and Its Immediate Dependencies, Comprising Interesting Details of Batavia, and Authentic Particulars of the Celebrated Poison-tree'']
