The Lake That Caught Fire

The first time I heard that a lake in my city had caught fire, I assumed it was a figure of speech. It was not. Froth had piled up along the edge in drifts high enough to blow across the road, and somewhere in that chemical meringue there was enough combustible material to catch. People filmed it from their scooters. The clips went around for a week, and then the city moved on, because a city can only hold so much at once.

What struck me afterwards was not the fire. It was how ordinary the causes were. A lake does not become flammable through any single dramatic act. It gets there through a thousand small permissions: sewage lines that were laid for a smaller population and never upgraded, detergent from a few hundred thousand washing machines, construction debris tipped at the edge because the edge was convenient, industrial effluent from units that were told to treat their water and found it cheaper not to. None of those is a scandal on its own. Together they are a lake that burns.

We tend to imagine environmental damage as something that arrives — a spill, a fire, a collapse. Mostly it accumulates. The dramatic moment is just the point at which the accumulation becomes visible enough to photograph. By then the interesting decisions are years behind you, taken in rooms with no cameras, by people who were each solving a reasonable short-term problem.

Bengaluru was built around water. The old tanks were a connected system, engineered so that the overflow from one fed the next, which is a genuinely elegant piece of design for a city on a ridge with no river running through it. What happened to that system was not primarily malice. It was land value. A tank bed is flat, well-drained ground in a city desperate for flat, well-drained ground. Fill it in and you have a bus station, a stadium, a layout of houses. Each conversion made local sense. The cumulative effect is that the water has nowhere to go, so it goes into basements.

This is the part I find hardest to write about honestly, because the satisfying version of the story has villains in it, and the true version mostly has incentives. The builder who fills a tank bed is responding to a market. The household whose greywater reaches the lake untreated is responding to an absent sewer line. The official who signs the approval is responding to a target. You can prosecute individuals and the system will produce replacements, because the system has not changed what it rewards.

That does not mean nothing works. The lakes that have recovered here recovered because somebody local refused to stop asking — residents who learned the relevant law, measured the inflow, filed the cases, showed up at the hearings, and kept showing up after the news cycle ended. Restoration is not a project with a ribbon at the end. It is maintenance, forever, by people who live close enough to notice when it slips.

I think about that when I water the balcony. The scale is absurdly different, and the principle is not. Things that are tended stay alive. Things that everyone assumes someone else is tending do not. A lake is just a very large instance of the same arithmetic, with the consequences distributed across a few million people instead of one household.

A lake that catches fire is not a freak event. It is a receipt.
