Floods seen from space
The Sentinel-1 radar satellite images Bengaluru every 6–12 days, through cloud and rain. We keep only the water it saw right after storms.
Bengaluru · flood history for any address
Know if a home floods before you sign.
Doobega reads fifty years of satellite records, the city’s own flood lists and a decade of reported floods — then tells you, for any Bengaluru address, whether it has flooded and whether it stands where a lake used to be.

The question no brochure answers
Bengaluru was built on its lakes. Some of them still remember.
No rule in India makes a seller tell you a home has flooded. Brochures show the lake view, never the lake bed. And after every monsoon the city forgets — until the next one.

How Doobega reads a place
Four kinds of evidence, checked for every city block.
We don’t hand you a mystery score. Every report shows what was seen, when, and by whom — so you can judge it yourself.
Water that used to be
Landsat has photographed the city since 1984. Where open water has vanished — drained, dried or built over — we tell you. Old lake beds tend to flood again.
Drains and low ground
A bare-earth terrain model shows where rain runs and collects. We measure how close a home is to the nearest storm drain, and how little it sits above it.
Official lists and real floods
The city’s own flood-prone and low-lying lists, plus every major reported flood since 2017, placed on the map with the source a click away.

Bengaluru’s vanished water
Scroll, and watch a lake disappear.
These outlines are real — traced from Landsat images by the European Commission’s Joint Research Centre. The dashed line is the water in 1984; the blue is what was left in 2021. Around Bengaluru, most water lost since 1984 has dried up or been drained. The lakes that were built over mostly vanished even earlier:
Built over before satellites were watching
Tested against real floods
We checked ourselves against the floods of 2024–2026.
Using only evidence that existed before each flood, how often would Doobega have warned the families who were flooded — and how often does it flag an ordinary home?
