Wawa Dam
Also known as: Montalban Dam · Wawa River Dam
Definition
Wawa Dam is an arched gravity dam of the American colonial era built in 1909 across the Marikina River at the Montalban Gorge in Rodriguez (formerly Montalban), Rizal. Constructed as part of Manila’s early twentieth-century water supply system, it is now retired from metropolitan service and functions as a scenic recreation site beneath the granite cliffs of the Wawa gorge.

Examples and Analogies
Wawa Dam is to Rizal Province what a small forgotten aqueduct is to an old city: superseded by larger works like Angat Dam, it remains as a monumental relic in a dramatic landscape, its gorge often compared to a miniature canyon at the foothills of the Sierra Madre.
Usage Scenarios
Visitors hike or take tricycles from Rodriguez town proper to swim in the reservoir pool, picnic on the riverside ledges, cross the dam crest, and photograph the twin limestone walls associated with the legend of Bernardo Carpio.
Strategies
Local government and community groups market Wawa as a low-cost eco-tourism day trip from Metro Manila, pairing it with hikes to nearby Pamitinan caves, and manage vendor zones to spread tourism income among residents.
Security and Safety Measures
Swimming is monitored because spillway currents and monsoon releases are dangerous; the gorge funnels flash floods during storms, so visits are suspended under red rainfall warnings, and the dam structure itself is off-limits beyond viewing areas.
Historical Context
Built under the Insular government to supply Manila before larger upland sources were developed, the dam’s water role faded as Angat and successive systems took over, leaving the structure and its colonial stonework as heritage; renewed proposals to tap the Wawa watershed have periodically revived its original water-supply identity.
Challenges and Controversies
Crowding, waste management, and quarrying pressures in the surrounding mountains are chronic issues, and any reactivation of the watershed for supply must be reconciled with recreation and the ecologically fragile Marikina upper basin.
