In a tragic incident, a female elephant, approximately 40 years old, has died after consuming polluted water from the Arkavathy River flowing through the Maggur range of the Cauvery Wildlife Sanctuary in Karnataka. The Arkavathy River is a major tributary of the Kaveri River originating at Nandi Hills, 60 km north of Bengaluru. The river, stretching across 53 km, was once was Bengaluru’s primary source of drinking water from 1936 to 2000 via the Tippagondanahalli reservoir.

The elephant's carcass was discovered around 5 pm on Monday (May 11). According to the post-mortem report, approximately 35 litres of water was found in the elephant's stomach, confirming the presence of toxic substances. Forest department sources have said that the elephant died due to drinking the contaminated water of the Arkavathy River.

A heart-wrenching scene

It was a heart-wrenching sight to see the deceased elephant's calf standing by its mother’s carcass and crying. This scene made the people on the spot teary-eyed.
What was more amazing is that other elephants from the herd eventually arrived, comforted the calf, and led it away into the forest.

Last rites

Upon receiving the news on Tuesday morning, officials from the Cauvery Wildlife Sanctuary Forest Department and veterinarians arrived at the spot to conduct an inspection.

After performing an on-site post-mortem, the elephant's funeral was conducted in accordance with forest department regulations.

Polluted Arkavathy River

The Karnataka Pollution Control Board (KPCB ) has recently categorised stretches of the Arkavathy near Kanakapura as Class E. This means that the water is so contaminated with fecal coliform and industrial waste that it is fit only for industrial cooling or waste disposal.
When elephants drink this water, they ingest high levels of pathogens. While a single drink might not kill them, chronic exposure leads to multiple organ failure and severe intestinal issues. Research reports have detected cancer-causing heavy metals, mercury, and DDT—a banned pesticide—in the river water.
Due to the direct discharge of industrial chemical waste and urban sewage into the river, the oxygen levels in the water have dropped drastically.

Tragedies in the river basin

The Arkavathy River has claimed the lives of elephants before.
IN November 2025, two wild elephants attempting to cross the backwaters of the Harobele Reservoir on the Arkavathi River in Kanakapura taluk, Ramanagara district, got trapped in the aquatic vegetation and drowned.

After the incident, environmentalists flagged the thick layer of aquatic weeds (Eichhornia) and silt, often fuelled by high nutrient runoff and sewage pollution, as a death trap. The elephants became entangled in the dense vegetation, grew exhausted, and were unable to pull themselves out.

With the death of this female elephant this week, near the Maggur forest in the Cauvery Wildlife zone, due to multiple organ failure and illness, wildlife experts have noted that polluted water and intestinal infections at the onset of the monsoon season are major causes of such deaths.

Unchecked urbanisation hits wildlife

While Karnataka remains one of the leaders in conservation, boasting a population of 6,013 wild elephants, the state is facing a grim paradox: it can manage the animals, but it cannot seem to protect their environment.

Despite pioneering safety measures like Rail Fence Barriers and launching ambitious rehabilitation plans for 300 elephants displaced into private lands, the government remains largely paralysed against the "silent killers" of rampant urbanisation and human encroachment.

This environmental neglect is effectively turning the state's conservation efforts into a battle for survival against a toxic landscape with elephants losing safe access to basic needs like clean water.
