Basai Pond's Eco-Crisis: Fish Deaths and Sewage Plague

Basai pond, a crucial urban biodiversity refuge, is facing severe ecological crises, according to a recent seven-day study. The assessment documented numerous stressors, including significant fish mortality, concerning sewage inflows, ritualistic food offerings, livestock pressure, invasive vegetation, and accumulating solid waste. The research, conducted between May 16 and May 22, recorded multiple fish deaths, including mangur and rohu species, across different zones of the pond.

Environmental researchers attribute the pond's decline to factors such as daily religious food offerings contributing to nutrient loading and sewage overflow, especially during heavy rainfall. Invasive congress grass now covers an estimated 70-80% of the pond's perimeter, suppressing native vegetation. Despite these pressures, the johad continues to support a diverse range of bird species, including great cormorants and Indian spot-billed ducks, as well as native tree species.

Concerns have escalated, prompting submissions to multiple government agencies, including the Haryana State Pollution Control Board and the Haryana Pond Authority. Recommendations include investigating sewage inflows, improving water quality monitoring, waste removal, and regulating livestock access. The pond is currently being de-watered in preparation for the monsoon season, while authorities promise to investigate and take appropriate action based on findings.
