After dead fish in Yamuna, government to investigate 'fake information'
What's the story
The Delhi Irrigation and Flood Control department has approached the police, seeking to file a complaint after hundreds of dead fish were found in the Yamuna River near Sonia Vihar. The incident is the second such occurrence in less than a month. The department, in its complaint, said "some unidentified individuals are spreading fake information on social media platforms, alleging that chemicals are being sprayed into the Yamuna, thereby disturbing aquatic life."
Accusations made
Water minister hints at possible connection to AAP workers
It said the posts were shared with "malafide intentions" of creating panic ahead of Chhath Puja on November 15 and 16.
Water Minister Parvesh Sahib Singh accused some people of deliberately dumping dead fish.
"As soon as ferry services started operating on the Yamuna...officials from our department informed me that some people were dumping dead fish into Yamuna," he said.
"An investigation will be conducted to identify who these people are and whether they have...connection to AAP workers," he claimed.
Water crisis
Fish deaths coincided with launch of Namo Yamuna River Safari
The latest fish deaths were reported after the launch of the Namo Yamuna River Safari, an electric river cruise.
A large number of dead fish were found along the Burari stretch in mid-October. Industrial effluents entering through drains 2 and 8 were suspected to have contributed to the deaths.
The latest incident also coincided with a deterioration in raw water quality from Yamuna, with ammonia levels rising to around 1.3 mg/l.
Production impact
Ammonia levels in Yamuna spike
The Delhi Jal Board (DJB) was forced to curtail production at its Sonia Vihar Water Treatment Plant for nearly five hours on Wednesday due to rising ammonia levels, IE reported.
All water treatment plants have been functioning normally since Wednesday evening, a senior DJB official later said.
The issue of high ammoniacal nitrogen concentration in Yamuna during winter isn't new, as pollutant concentration increases when river water decreases post-monsoon and during winter.
Expert opinion
AAP's jibe at Delhi minister
AAP MLA Saurabh Bhardwaj posted a video of the dead fish, alleging that some harmful chemicals were being released into the river to make it appear clean ahead of Chhath.
"Minister @p_sahibsingh is verbally saying that dead fish were brought from somewhere and dumped into the Yamuna, but...Everyone knows the fish must have died from polluted water. Perhaps they got scared that an investigation would expose the Yamuna's pollution. Will the government order an investigation into how....fish died?" he asked.

Bhardwaj shares video
मंत्री @p_sahibsingh मौखिक कह रहे हैं कि मरी हुई मछली कहीं से लाकर यमुना में डाली गई मगर शिकायत में ये बात कहीं नहीं लिखी है । 😂

सभी जानते हैं मछलियाँ प्रदूषित पानी से मरी होंगी।
शायद डर गए कि जाँच होगी तो यमुना के प्रदूषण की पोल खुल जाएगी ।
सरकार जांच करवाये कि हज़ारों… https://t.co/BSGt9daw06 pic.twitter.com/ld0jm1dJBa
