In addition to rivers flowing in extreme flood situations at 64 flooding monitoring stations during Southwest Monsoon 2024, we have found that rivers have crossed highest flood level (HFL) at four stations during just concluded Northeast Monsoon season. Of these four stations, three are in Tamil Nadu state and one is in Union Territory of Puducherry.

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.

DRP 060125: Concerns about & Contradictions in CGWB’s Reports
The Central Ground Water Board (CGWB) released two important reports last week. While the Annual Ground Water Quality Report 2024 reveals rise in nitrate fluoride, arsenic and uranium contimination of groundwater resource in India, the Dynamic Groundwater Resource Assessment Report 2024 claims substantial rise in annual groundwater recharge and decline in extraction of the resource.
As per the first report, the number of districts affected by high nitrate levels in groundwater has gone up to 440 (near 56% of all 779 districts in country) from 359 found in 2017 assessment which means in 7 years 81 more districts have been found having excessive nitrate levels in groundwater. This should concern us from a number of points of view.

This annual overview focusses on the functioning of National Dam Safety Authority (NDSA) and related institutions in 2024 to understand if the functioning of these institutions have made Indian Dams any safer? Here functioning of Central Water Commission (CWC) is also important as CWC people head all the dam safety panels. The dam safety related institutions were formed following the passage of Dam Safety Act 2021 and hence there were promises and hopes that these institutions will make our dams safer.

This annual overview focusses on important reports highlighting the corruption issues related to the hydro and dam projects in India in 2024. The electoral bond case has revealed the deep nexus among political parties, contractors and financers as dominant force working behind the projects overlooking the evident disaster risks and undermining the democratic process. As a result, the people, rivers and environment are made to bear the burden and burnt.
The part 1 of the yearend roundup has documented the accidents and disasters related to dam and HEP projects in India in 2024. The part 2 focuses on community resistance against hydro projects in Himalayan states. The part 3 covers the struggle of dam projects affected people. The part 4 highlights growing concerns against pump storage projects.

Having covered dam induced flood incidents and embankment breach flooding events in part 1 and part 2, this third part on annual overview compiles media reports on manmade Urban flood disasters in India during the year 2024. While the cities of Pune, Nasik, Nagpur, Vadodara and Bharuch were affected by dam induced floods, the high discharges from Prakasam barrage and multiple breaches in Budameru river deluged the Vijayawada city. Interestingly, these urban flood episodes coincided with heavy rainfall events giving a reality check to dam and city managers.
In addition to failure in dam management, the deluge in Pune, Vadodara and Vijayawada city were particularly worsened by river front development projects and encroachment on river floodplains putting question marks on the urban planning and development works in these cities. Similarly, the breach in embankment of Munak canal in Delhi flooded several homes Bawana area during the monsoon season.

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.

2024: Dam Induced Floods in India

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.

This twelfth edition of monthly Yamuna updates and the first one of the new year 2025, rounds up the critical issues impacting the river eco-system during the past year. The updates of the past one month only hint towards the bleak future the river is heading to. Without addressing the adverse effects and exploring cost effective alternatives, foundation stones of two massive river interlinking projects namely Ken-Betwa and Parbati-Kalisindh-Chambal have been laid. The work of unjustifiable Renuka and Lakhwar dams in climatically sensitive and geologically fragile region of Himalaya is going on.
