Monsoon rainfall has reduced some pollution levels in the Yamuna River, but water quality remains below safety standards.
Reader brief
Through the Reader lens: Recent monsoon rains have provided a temporary improvement in the Yamuna River's water quality by diluting accumulated sewage and increasing dissolved oxygen levels. However, critical pollution indicators such as fecal coliform and biochemical oxygen demand remain far above safe limits for bathing. Experts suggest that higher water diversion levels at the Hathnikund Barrage have limited the river's ability to receive the necessary flow for effective cleaning.
What to watch next
- Future trends in dissolved oxygen levels as monsoon flows fluctuate.
- Potential policy adjustments regarding water discharge thresholds at Hathnikund Barrage.
- Long-term impact of altered canal diversion operations on river health.

During the 2023 Delhi floods, the diversion to the canals was stopped once upstream water influx breached 50,000 cusecs and all was released to the main river. “ However, the threshold for when water must be released into the main river was raised from 60,000 cusecs to 70,000 cusecs and subsequently to 1 lakh cusecs from 2024.
