As we saw in stories in last week (e.g., Luhri HEP in Himachal Pradesh) and see this week (Vishnugad Pipalkoti in Uttarakhand and Dibang HEP in Arunachal Pradesh), a number of under construction projects regularly face disaster, which includes deaths and destruction on large scale. We have been narrating stories related to disaster at such projects regularly in the past too.

The news this week that India and Bangladesh have agreed for India to help Bangladesh conserve the Teesta River that flows from India to Bangladesh. We hope this development is taken to its logical conclusion soon in terms of implementation of the project as soon as possible. This has the potential to not only two nations working together on conservation and rejuvenation of the Teesta River, but also possibly other 53 shared rivers. However, it would have been better if the W Bengal government would have been briefed, taken into confidence and involved in the discussions. History tells us that the cooperation efforts do not succeed without the involvement of all the stakeholders.
The formation of Joint Technical Committee to initiate discussions for the renewal of the Ganges Water Sharing treaty 1996 that will expire in 2026. One hopes that all these happen with a benevolent disposition from India as this has the potential of creating a much stronger bond between the two countries. A good example is the 1996 Ganga treaty that was also signed with a benevolent disposition. This move can also help strengthen the relations across South Asia as both Nepal and Bhutan are hoping to export hydro-electricity to Bangladesh via India.

As the two reports from media today shows, Karnataka is facing drought in 223 of 236 talukas, water scarcity and even farmer distress and suicides. The state government is aware of the situation and taking necessary measures. The situation could be similar in a number of states including Maharashtra, Telangana, Andhra Pradesh and even some of the eastern and northern states. The North Himalayan states have experienced hugely below normal snowfall in the ongoing winter. The Winter Rainfall at all India level for the period Jan 1 2024 to Feb 25 2024 is already 31% below normal.
There is role of global warming and El Nino in this and these factors are going to persist at least till the end of Indian Summer. So the governments both at centre and in states needs to be ready for the crisis.
The current Karnataka govt is awake to reality and seems to be taking the appropriate steps. Karnataka had deficit rainfall in SW Monsoon 2023.

In this third annual overview on dams and hydro power projects, we have compiled the reports on flood disasters caused by unscientific or improper operation of dams, hydro and barrage projects in India in 2023. The report highlights criminal negligence by SSNNL and BBMP resulting in massive flood destruction in parts of Himachal Pradesh, Punjab, Gujarat and Madhya Pradesh.
Similarly, the sudden discharges from hydro power dams in Assam, Himachal and Uttarakhand have caused flash flood deluge damaging human properties along the respective rivers. The report also covers some incidents of barrage induced flood events along Ganga in Uttar Pradesh and along Yamuna in Delhi. The first part of the series on Hydro and dam related accidents and second part on People’s Protests against Hydro & Dam Projects in India in 2023 can be seen here and here respectively.

DRP NB 131123: Another Himalayan Disaster: 40 workers trapped in a tunnel in Uttarakhand
(Ongoing rescue work inside Badkot-Silkyara tunnel in Uttarkashi. Image Source: HT)
In yet another disaster in the Himalayas, at least 40 workers are trapped in an under-construction tunnel being constructed by National Highways & Infrastructure Development Corporation Ltd. (NHIDCL), among others. The Hindustan Times has wrongly named the construction company as Hydroelectricity Investment & Development Company Limited (HIDCL) possibly of Nepal govt. Some people at the location have informed us that it may take another day before the workers are rescued.
NHIDCL was not even sure of the total of number of workers, as they gave the number as 36, which was corrected by the district administration later on to 40. It is also strange to see the work going on even on a Diwali day. Another disturbing aspect is that all the workers are reportedly mostly from outside Uttarakhand, when Uttarakhand villagers are known to migrate in large numbers to outside the state for employment. This disaster thus raises a lot of questions, which will need answers once the workers are rescued safely. The workers are still trapped over 30 hours after the disaster. The work at the 4.5 km long tunnel is being built under Char Dham Road Widening project since over 4 years, and violations have been happening in the work since then, as we reported in 2019.

DRP NB 290523: Goa Fights to save Mahadayi River
(Feature Image: Thousands form human chain along Mhadei river to celebrate #MahadaiAmchiMai festival. Source: ToI)
On May 20, 2023 when thousands of people of Goa, Rakhondars (protectors) came out to form a 7 km long human chain to save Mhadei or Mahadayi river, they were not only celebrating Goa’s unique Mahadayi River festival, but were also coming together to declare their resolve save and rejuvenate the River that is lifeline of Goa.
A large number of organizations came together, including Earthivist Collective, Goa Heritage Action Group, Save Mhadei Save Goa front, among many others. It was a unique attempt to reconnect with the river, its history, its soul. The people from all kinds of art forms and all walks of life came together in a state where the connection with the river has always been strong for the people.
One hopes their tribe multiplies and they succeed in saving the river from dam building plans and other river affecting activities. That success will provide an example and impetus for river conservation activities elsewhere too.

DRP NB 090123: Atal Bhujal Yojana just chaff without any wheat?
According to this detailed report, possibly the first independent review of the Atal Bhujal Yojana, a 5-year program of the Union govt for management of groundwater, India’s water lifeline, with over half of the project period completed, seems bereft of the fundamental aspects that the scheme itself says are necessary for any sound foundation of the scheme. The review describes it as a dish full of chaff, without almost any kernels of wheat for some sound reasons. It says hardly 18% of allocated money has been spent on Gram Panchayat level community-led Water Security Plan. Only 4% of the planned Gram Panchayat level trainings have been held, with Gujarat and Haryana holding none. Only 27% of money allocated for Gram Panchayat level Hydrogeological monitoring network has been spent. The data gathering instruments that were required from the beginning of the program have not been installed in over half the planned locations. On Information, Education and Communication activities, only 16% of allocated amount is spent.
More detailed independent review of the program implementation will help, but from the available information so far, the signs do not look particularly promising. Is it due to ineptness or lack of intention? Only time will tell.

2022: When Polavaram project further unraveled
(Feature Image: Flood water discharging from Polavaram Project to the downstream, in West Godavari district, on Jyly 12, 2022. The Hindu)
Polavaram is the largest and costliest big dam project under construction in India currently, though not much has been written about this projects and its impacts in mainstream in India. The project was given various clearances through a manipulated process, basic studies were not done before clearing it. Several petitions are pending before the various High Courts and the Supreme Court of India, but the project is allowed to go ahead without resolving them or the inter-state issues. A number of issues related to the project has been unravelling over the years and in 2022, the project further unraveled as the news reports compiled here reveal.
A snapshot of the status at Polavaram Project: The downstream coffer dam is damaged, the Gap 1 and Gap 2 of the Dam are yet to be constructed, the 1.7 km long Diaphragm wall of the ECRF dam is submerged in flood waters, it was earlier damaged (scoured at two places over an an area of 200 m X 200 m) in 2019 floods implying additional expenditure of Rs 600 cr, the water flow at the dam site on July 15, 2022 was highest since 1920 for July, the assessment of the earlier damage to the diaphragm wall and future options that was underway when the floods struck in the second week of July 2022, had to be stopped while still incomplete, the rehabilitation colonies have been submerged as the engineers assessment proved wrong about their elevation. There is an uncertainty on the structural stability of the other facilities of the irrigation project due to incomplete construction of the main dam, as it is receiving an unprecedented inflow. The height of the upper Coffer dam was increased by 1 m to 44 m between 17 and 19 July, 2022, in the middle of high floods, but that had impact on upstream Telangana and they opposed that this was done without consulting them.

Dam Floods, Failures and Disasters in 2022
This annual overview highlights the dam induced flood disasters, dam failure incidents in India during 2022. This year, the massive floods in Godavari have exposed the flood vulnerability of giant projects like Polavaram and Kaleshwaram. Also there have been multiple dam failures and dam induced floods in Madhya Pradesh, Tamil Nadu and Kerala. In absence of coordination and data sharing Hirakud induced floods in Mahanadi basin have affected several villages in Odisha and Chhattisgarh. There have been several instances of unscientific operations of dams and the operators continue to hide behind TINA (There Is No Alternative) excuse. The functioning of CWC as key flood forecasting and management agency has not shown any significant improvement. However, now it has accepted that faulty dam operations can lead to flood in downstream areas. Please see links to our 2018, 2019, 2020 and 2021 annual compilations on the subject.
