Mookervaart River

The Mookervaart was originally constructed in 1678 to 1689 to draw one-third of the water flow from the Cisadane River and link to the city canals of Batavia, to control the flood. 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. Nonetheless, the Mookervaart still supplied the most water to Batavia in the 18th century. ==Hydrology==
