Molteno Dam, Embankment dam on Table Mountain slopes, Cape Town, South Africa.

Molteno Dam is a small embankment dam on the lower slopes of Table Mountain in Oranjezicht, Cape Town. Built in 1877, it stores water from mountain springs in sandy, porous clay, using a mix of excavation and masonry-supported embankments. It remains in service and sits beside De Waal Park.

Built in 1877 as part of Prime Minister John Molteno's infrastructure programme, the dam stored water from Table Mountain springs for the growing city. In the 1880s it was overfilled and breached, sending a flood through Cape Town that destroyed houses and uprooted trees. After repairs it continued supplying the city centre.

The dam takes its name from John Molteno, the Cape Colony's first Prime Minister, whose government launched the infrastructure programme behind it. The reservoir and the nearby Molteno Spring feed the old waterway the Khoi called Camissa, "Sweet Waters"; a community programme works to restore these historic city streams.

The dam sits in the hills above the city center and can be reached on foot or by car depending on your starting point. The terrain is hilly, so sturdy shoes are recommended for exploring the surroundings.

The reservoir's water still feeds the Company's Garden, and the dam sits beside De Waal Park as a free public recreation area. It forms part of the old Camissa waterway, Khoi for "Sweet Waters", which ran through early Cape Town's streams and grachts.
