The lake functions as a critical part of Jakarta's micro-drainage system designed to mitigate seasonal flooding in the Pesanggrahan watershed.
The name 'Cavalio' is often associated locally with the surrounding residential cluster rather than a natural geological feature.
The reservoir acts as a sediment trap, requiring periodic dredging to maintain its depth and water storage capacity.
Danau Cavalio is a small, functional urban reservoir located in the Pesanggrahan district of South Jakarta, primarily serving as a flood control retention basin. The site features a surrounding path used by local residents for informal morning and evening exercise. The water body is contained within an engineered embankment, separating it from the densely populated residential streets of the Bintaro and Pesanggrahan border area. Its primary utility lies in water management, though it functions as a localized green space for the surrounding neighborhood. The perimeter is accessible via the Jl. Inspeksi maintenance road which runs alongside the lake's banks. As of August 2026, the facility remains an active infrastructure site under the management of the Jakarta municipal government.

Visit during the dry season to avoid muddy or flooded conditions on the inspection path.
Wear comfortable footwear suitable for walking on uneven, unpaved surfaces along the perimeter.
Exercise caution as this is an active municipal facility with minimal pedestrian amenities or security personnel.
Do not attempt to swim or fish in the reservoir as the water quality and safety conditions are not monitored for public recreational use.
Maintain a respectful distance from water management equipment and avoid blocking the inspection road.
