PANAJI: A lake choked by dead fish has brought the Bombay High Court into Goa’s environmental crisis, with judges directing authorities to take “immediate remedial measures” to halt the deterioration of Mala Lake’s water quality. The suo motu public interest litigation, triggered by reports of large quantities of fish floating dead on the water surface, has now forced a judicial inquiry into what killed the lake — and who is responsible.
The division bench suspects sewage discharge as the primary culprit. To trace the source, the court has directed the corporation commissioner to inspect the area and submit a detailed plan of all houses within a 200-metre radius of the lake, including house numbers and their exact locations. The same plan must mark whether a sewage line is available. If not, an affidavit must explain how residential waste is being disposed of. The numbers are alarming. Tests conducted on April 11 showed dissolved oxygen levels at 0.8 milligrams per litre — one-fifth of the normal control level of 4 milligrams per litre. After sluice gates were opened, oxygen levels rose to 11.8 milligrams per litre by April 13, confirming that stagnant water and restricted flow were major contributors. The state’s advocate general told the court that possible reasons include stagnant water, algae growth on the lake bed, or sewage discharge. Bacterial content test results are expected shortly.
The bench made its urgency clear, stating that measures must be taken quickly before “irreversible” damage occurs. A court-appointed amicus curiae will assist in the proceedings. Multiple state agencies — including the pollution control board, health services, sewerage development corporation, fisheries department, and water resources department — have been asked to respond. For urban residents of Panaji, Mala Lake is not just a water body. It is part of the city’s natural drainage and flood resilience system. A dead lake cannot absorb monsoon runoff, cannot support biodiversity, and cannot cool its surrounding neighbourhood. The court noted that a pumping station and sewage treatment plant sit near the lake’s northern side, while extensive paddy fields and residential houses line its southern and northern boundaries — all potential pollution sources.
What makes this case significant is the judicial insistence on mapping. By demanding house-by-house data within a 200-metre radius, the court is effectively creating a pollution ledger. Each household without sewage connectivity becomes a data point. Each missing pipe becomes evidence. The lake may yet recover. Dissolved oxygen can rise if flow is restored and sewage inflow stops. But the deeper question — how many other urban water bodies in Goa are silently dying — remains unanswered. The court has asked for answers. The lake’s fish have already given theirs.
