In the early hours of 1 June 1905, a record storm broke the dam that held Durban's water, and the flood swept down the Umbilo valley onto the homes of Indian market gardeners. The Short follows Muniamma, a fictional market gardener on the riverbank, from the afternoon the rain began to the night the water came. This is the history behind it.
Families in Durban today descend from people who lived through this night. This entry keeps to documented facts and says where the accounts disagree.

The day, hour by hour
1884 to 1887
Durban's waterworks
The town council bought land above the Umbilo waterfall in 1884 and finished a storage dam and a settling dam in July 1887. Pipes carried the water about 12 km toward Durban.34

Durban drinks from the dam up the valley. So do my beans!

Rain and hail
Torrential rain and hail swept in from the afternoon of 31 May and spread across Natal. Pinetown's gauge would measure 397 mm between 3 pm and 6 am.12
KANNAN
Amma, hail! And the river is over the path!

Blocked at Pinetown Bridge
Logs, bamboo and debris piled up against the railway bridge at Pinetown. Earlier storms on the river had passed without disaster.35
MUNIAMMA
Storms come, storms go. The river always falls by morning.
1 June · about 1:45 to 2:10 am
The dam breaks
The railway bridge gave way and the surge hit the storage dam, which failed and released about 150 megalitres down the valley. One reconstruction puts the breach at about 1:45 am and the flood at South Coast Junction about 25 minutes later.35

That night
The valleys flood
The water swept away homes along the Umbilo and Mhlatuzana, most of them belonging to Indian families. A Hindu temple on the Umhlatuzana was wrecked.12
Hundreds drowned in these valleys that night, most of them Indian families.
Afterwards
Never rebuilt
Durban had other water supplies by then, so the dam was never rebuilt. Its ruins, from the dam wall to the filter beds, lie in Paradise Valley Nature Reserve, a provincial heritage site.34
Its ruins lie in a nature reserve called Paradise Valley.

Muniamma is fictional. The broken dam is real.

Open question
Open question
Who was to blame?
One account, drawn from Laljeeth Ramdhani's 1984 study, says Durban's council and mayor denied that the dam caused most of the deaths and gave no aid to those affected, while a government inquiry found the burst waterworks was the main cause.5
The same account says the river had never been managed for floods and the railway bridge at Pinetown was too narrow for one.5 How much of the loss the dam caused, and who should have seen it coming, the surviving record does not settle.
Medium
Think about it
Most of the people who died lived on the river flats outside the town's care. How might that have shaped the warnings, the help and the count of the dead?
The death toll ranges from 137 to 300 depending on the source. Why might an official count and later estimates disagree?
The dam was built to give Durban clean water. What does a city owe the people who live downstream of its dams?
The 1905 rain record still stands, even after the floods of April 2022. What would you want to know before saying a flood like it could happen again?
