The findings of the latest Project Dolphin Survey Report released on March 3, 2025, by Prime Minister Narendra Modi in presence of Union Environment Minister Bhupendra Yadav have raised significant concerns over proposed Pachnad Major Irrigation Project.

While the survey reiterates the adverse impacts of dams, barrages fragmenting the national aquatic animal’s habitat as the population has been found nearly absent between Narora barrage and Kanpur barrage stretch in main stem of Ganga, it also reveals that the endangered species are preferring refuge in Ganga tributaries and confluence points and has been found in highest numbers along 47 km long river stretch between Chambal and Pachnad in Bhind which still undammed.

दिल्ली विधानसभा चुनाव प्रचार के दौरान यमुना नदी प्रदूषण एक महत्वपूर्ण राजनितिक मुद्दा बना। चुनाव जीतने के बाद स्वयं प्रधानमंत्री और भाजपा पार्टी के वरिष्ठ नेताओं ने ‘आप’ सरकार की हार के लिए यमुना की दुर्दशा को एक प्रमुख कारण बताया। साथ में यमुना को साफ करने की बात कही। ऐसे में क्या दिल्ली के नागरिक एक स्वच्छ बहती नदी की उम्मीद रख सकते हैं?

While we celebrate World’s Wetlands Day 2025 with theme of “Protecting Wetlands for Our Common Future”, the top ten reports from 2024 show that the plight of wetlands in India remains miserable making the future of the waterbodies and dependent people uncertain. While govts continue to be lethargic in identifying and notifying the wetlands in the country, the govts initiated developmental plans, projects are further making them vulnerable to extinction. Amid this the threats from encroachment, siltation, pollution and climate change are only increasing. Also see the first part of the overview highlighting the deteriorating situation of Ramsar wetlands in India.

This annual overview complies the remaining relevant reports from 2024 concerning safety of dam structures in India. As per a report, the incident of damage to Tungabhadra dam gate in August 2024, raised alarm for other aging dams in Karnataka. In fact, the Bhadra dam also witnessed jamming of a gate due to rust in June 2024. Similarly, the Kabini reservoir has been dealing with a leakage for the past three years. The report further highlights negligence in dams’ monitoring and inadequate expertise and corruption often impacting the quality of maintenance works of dams in the state. As per another report taking sou moto action, the Karnataka High Court in January 2024, banned mining and blasting activities within a 20 km radius of the Krishna Raja Sagara dam in the state.

Besides the dam induced flood events, the available media reports show two incidents of breach in industrial dams causing substantial flood damages to local people in India during 2024. The first incident took place in NMDC’s iron ore mine in Kirandul area of Dantewada district in Chhattisgarh in July 2024 in which collapse of an iron ore waste ‘check dam’ resulted in extensive flood damages in downstream areas.

The second such incident happened in September 2024 when aluminium mine waste dyke breached in Vedanta Alumina Lanjigarh facility in Kalahandi district of Odisha flooding scores of farmlands with toxic mud. Interestingly both the NMDC and Vedanta have blamed extreme rains reason behind the breach in their mine waste collection facilities while the reports indicate negligence in maintenance of these dams.

This 2024 annual overview focusses on important reports highlighting the safety and sustainability issues of the hydro and dam projects in India in 2024 in the context of Climate Change, including Glacier melt and GLOFs. The compilation shows that the climate change driven extreme weather events have become significant threat for the structural safety of these projects.

This is even more relevant in inherently vulnerable areas like the Himalayas and Western Ghats from the point of view of seismic activity, young erosion prone mountain, flash floods, avalanches and landslides. Here the impact of climate change effects like more intensified hydrological cycles, cloud bursts, reduction in snow fall, glacier melts and GLOF (Glacier Lake Outburst Flood) increase the vulnerability including landslide dams and avalanche dams.

India has seen several floods brought by breach of embankments during the 2024 monsoon. In Bihar, though the state has received deficit rainfalls, the overspilling of barrages and breaching of several embankments created widescale flood damages. Number of reports have again highlighted the ineffective and adverse role being played by flood protection structures in worsening the deluge impacts. The first part of the overview has covered dam induced flood incidents in the country during 2024 and third part has highlighted incidents of dam induced urban floods.

India has seen several manmade flood disasters during the 2024 monsoon. The mismanagement of dams in Narmada valley including Bargi, and SSP inundated several dam affected villages despite adequate actionable advance warnings. The uninformed excess releases from DVC dams have led to flooding in large areas in West Bengal as repeatedly raised by the state government. The extensive floods in Tripura have revealed glaring loopholes in flood prevention and disaster management.

The floods in the year have also washed away or damaged several earthen dams, tanks in Madhya Pradesh and Rajasthan affecting human population, agricultural lands in their vicinity. Even during Northeast monsoon, the sudden releases from Sathanur and Veedur dams in Tamil Nadu created avoidable flood damage in downstream areas. Similarly, the states of Gujarat, Telangana, Haryana and Delhi have seen deluge due to mismanagement or breaches in the canals. The case of Narmada canal waters flooding large areas of Little Runn of Kutch is quite concerning.

A recent CIFRI (Central Inland Fisheries Research Institute) report submitted to NGT is an eye-opening official document about the fish diversity in Yamuna. The report says that overall native fish species have declined sharply in the river not only in number but in size also due to habitat degradation, pollution and increasing presence of invasive fish species.

The report admits that construction of Farakka barrage has led to complete elimination of Hilsa fish in lower segment of river since 2010. Among other recommendations the report has suggested maintenance of continuous flows in the river and addressing sources of pollution.

Indeed, the freshwater fish species are key indicator of health of a river eco-system and the fish diversity in Yamuna has been pushed to brink by the water abstraction, unsustainable riverbed mining activities and ever-increasing pollution of river waters besides other factors.
