A massive landslide (location: [27.2515, 88.4594]) at Dipu Data near Singtam in Gangtok district that brought down a huge part of a hill above the power house of the NHPC’s 510 MW Teesta V hydropower project on Teesta river in Sikkim at 7.30 in the morning of Aug 20 2024 has damaged the power house. The GIS building above the underground power house located at Balutar can be seen getting destroyed in the massive landslide and getting buried under the debris. The project has been out of operation since the Oct 4 2023 GLOF disaster in Teesta river[i] had over topped the dam and seriously damaged the project.

DRP 190824: Goa River group win important battle against illegal sand mining

This is indeed a rare and important victory by Goa River Sand Protectors’ Network (GRSPN) in their long fight against illegal river sand mining in Goa. Following a petition in the National Green Tribunal the state government has agreed to recall all the environment clearances granted by the State Environment Impact Assessment Authority.
Goa government has agreed since these clearances were given without a District Survey Report (DSR) as required under the sustainable sand mining guidelines of MoEF. While this may sound like a temporary respite based on some technical violation, the fact is most sand mining clearances across India are given without a credible DSR, but it has not been possible to stop such violations elsewhere.

One of the heartening development this week is from Kerala, where Chalakudy river community held a satyagraha to demand proper integrated dam management plan in the Chalakudy River basin to minimize flood risks. It is rather rare that communities come out for such a demand. It was also great to see that the satyagraha was supported by Chalakudy Puzha Samrakshan Samiti, Chalakudy municipal chairman and also environmentalists.
The satyagraha in fact had specific demand for each of the dams included in the Paramibikulam Aliyar Project, including in Kerala and upstream Tamil Nadu. We hope the Kerala government positively responds to these demands at the earliest.

(Feature Image by Cartoonist Alok/ Sakal, July 25, 2024)
This monsoon has again shown how our cities have been failing the monsoon test for decades. As rightly suggested in the Indian Express Edit this week, main reasons are: outdated drainage systems, planning that is blind to local hydrology and pathetic state of civic agencies. The last factor in fact needs to change to failed governance at all levels. There is no water or flood policy that guides our cities, nor is there any reward for improving governance, nor any penalties for lack of it.
In fact, with better rainwater management, cities can convert this problem into a blessing, both in terms of water security and also improved state of urban landscape. This would be possible if it prioritizes the city’s capacity to hold, store, recharge and drain the rainwater. Instead, the cities are busying destroying such capacities by destroying the rivers, ridges, forests, local water bodies, groundwater recharge capacities and also the drainage capacity.

(Feature Image: Officials said it was very important to identify a dry area for construction of the diaphragm wall and the earth-cum-rock-fill dam on top of it, this being the main dam of the Polavaram project. DC Image)
The floods last week in Pune, with significant contribution from dam releases from upstream has led to Maharashtra deputy Chief Minister Ajit Pawar directing the water resources department to keep the Khadkwasla Dam only half full to avoid repeat of the floods. While this is welcome and needs to be implemented, it also raises a number of questions.
The phenomena of water releases from dams contributing to downstream floods is not new, it has been going on for decades as SANDRP has been pointing out. Even in 2023 monsoon, several dams were found guilty of this including Sardar Sarovar on Narmada in Gujarat and Bhakra & Pong dams in Punjab (this was highlighted at a meeting in Chandigarh on Saturday by SANDRP and others), among others. In 2019 floods in Maharashtra and Karnataka too this happened in Krishna basin. So, the minister’s statement post disaster is surprising.

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.

(Feature Image: Flood-affected people move to a safer place on a boat in Nalbari district on Friday, July 5, 2024. Image Credit: PTI/Source HT)
We are in the thick of monsoon and also flood season. To manage floods, key inputs are accurate forecasts and prompt, accurate, location, river specific rainfall. India Meteorological department has a key role to play in all these aspects that can help us manage floods, as a very pointed Editorial in Indian Express stated in the context of Assam Chief Minister Himanta Biswa Sarma’s flip flops.
The edit referred to the 2021 parliamentary panel report that asked the Centre to set up modern weather stations in the upstream catchment of the Northeast’s rivers and install sirens to alert people downstream of floods. North East and rest of the country continues to lack such systems.

(Feature Image: Work going on Polavaram Project at Polavaram in West Godavari. DC Image: Narayana Rao, Dec. 2020)
The sequence of events over the last two decades that ended this week with white paper on Polavaram project being released by the newly elected Andhra Pradesh govt underlines urgent need for an independent assessment of the multi-state Polavaram Project on Godavari River in Andhra Pradesh.
The story of the project similar to, though a bit longer than that of the ill-fated Kaleshwaram Project of the neighbor Telugu speaking state of Telangana. Both are ill-conceived, expensive, high impact projects on same Godavari River, both taken forward without sufficient studies and implemented without sufficient checks and balances.

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.

(Feature Image: Sardar Sarovar Dam. Image Source: The Economic Times, Sept. 2022)
The news this week that SSNNL has decided to operate the 1200 MW River Bed Power House and the 250 MW Canal Head Power house to reduce the water level in Dam from 122.28 meters on June 14 to around 115 m before the monsoon inflows start, in anticipation of the above average rainfall anticipated during SW Monsoon 2024 is welcome. One hopes this is sign of SSNNL, Gujarat Government and the Narmada Control Authority have learnt some lessons after the avoidable flood disasters brought by SSP in 2023 and earlier in 2019 and 2020, as revealed by SANDRP’s analysis in each of these years.
One hopes this is not just one-off ad-hoc decisions, but part of a systemic change. This will require an integrated basin level reservoir operation policy including all the major dams of the Narmada Valley and put it out in public domain along with clearly defined Standard Operating Procedure, and names of the responsible officials for each of such major dam in the basin. The Central Water Commission will also need to be held accountable for its flood forecasting including the 7-day advance forecasts.
