During southwest monsoon season 2024, SANDRP has tracked at least 64 flood forecast and flood monitoring sites where the respective rivers have crossed the highest flood levels (HFL). Here we present detailed analysis of these sites along with some key observations and other relevant information. SANDRP’s previous reports on the subject can be seen here: HFL breach incidents in 2018, 2019, 2020, May-Sept 2021, Oct.-Nov 2021, May-June 2022, July-October 2022, June-October 2023.

DRP NB 020924: HYDRA to protect water bodies in Hyderabad – a landmark move?

The Hyderabad Disaster Response and Asset Monitoring and Protection Agency, or Hydra was established under GO 99, dated July 19 2024. A task the agency has taken up in all seriousness is protection of water bodies in the Hyderabad Capital Region (it includes 4 districts). To begin with it has started demolition of buildings illegally built inside the Full Tank Area (FTL) and Buffer area of the water bodies.
In July, Telangana Chief Minister Revanth Reddy replaced the Enforcement, Vigilance and Disaster Management (EVDM) wing of the government with Hydra, a body mandated to tackle illegal encroachment on water bodies in the Greater Hyderabad Municipal Corporation (GHMC) limits and surrounding areas. Its strength was upgraded from around 800 to 2,200 and its officials came directly under the principal secretary, municipal administration and urban development or the CM himself. “Hydra will also ensure the protection of water bodies in and around Hyderabad,” former EVDM commissioner and Hydra chief A V Ranganath said during its inception.

DRP NB 010724: Time for independent review of Polavaram Project?

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.

DRP NB 181223: Varanasi’s illegal tent city inaugurated by Prime Minister in Jan 2023
(Feature Image: Collage of Sentinel Hub satellite images of Tent City location in Ganga river bed in Varanasi from Nov. 26, 2022 to Dec. 11, 2023)
While the NGT putting a stay on the Varanasi Tent city and imposing a fine of Rs 25000 on MoEF for not responding to NGT about how the turtle sanctuary was denotified is welcome, we hope NGT takes it to its logical conclusion. It is strange, to say the least to see the NMCG telling NGT through its one page report dated Dec 13 2023 that the Varanasi Development Authority proposal dated Nov 28 2023 for tent city is under consideration! The Tent city companies were fined by NGT, but UP PCB is yet to do anything to collect the fine. Most interestingly, the Prime Minister, no less, inaugurated the tent city project on January 13 2023, over 11 months back! And very shockingly, none of the National Media is even reporting this remarkable situation.

The analysis of hydrographs being published on Center Water Commission’s (CWC) Flood Forecasting website shows that the previous Highest Flood Levels (HFL) have been breached at least at 34 flood monitoring sites across the country in July 2023. The river basin wise details of all these sites are given in tables below.

Rivers Breaching High Flood Level in June 2023
In the first month of South West (SW) monsoon season June 2023, there have been Highest Flood Level (HFL) breach incidents at two sites. Both of these sites namely Suklai on Suklai river and DRF on Puthimari river are level monitoring sites located in Baksa district of Assam in Brahmaputra basin.
Interestingly, the old HFL at both sites were attained in 2020 and 2022 only and the old HFLs were breached thrice between June 15 and 20, 2023. The details of old and new HFLs for these sites are given in table below.

India Lost 10 More Gangetic River Dolphins In One Year in 2022-23
(Feature Image: Post mortem being done of a dolphin carcass found at gate number 01 of Girija barrage in Bahraich, UP. Image Source: Dainik Bhaskar, Nov. 2022)
May 18, 2023, would mark 13 year of declaration of Gangetic dolphin as a national aquatic animal. However, the habitats of this ‘highly endangered’ species continue to suffer anthropogenic threats including wrong operations of dams & barrages, inland waterways projects, decreasing flows & increasing pollution in rivers, sand mining and poaching etc. in India. As a result, there are frequent incidents of mysterious and unnatural deaths of these fresh water mammals.
SANDRP has been tracking such incidents since January 2020 and our previous two reports published in January 2021 & April 2022 on the subject have complied deaths of at least 21 Gangetic dolphins in 2 years (2020 and 2021). In continuation of the same, this account covers the incidents of deaths of Gangetic river dolphins during past one year.

2022: Accidents & Damages related to Hydro projects in India
In this annual review, SANDRP compiles the hydro power related accidents, disasters and damages in North West and North East Himalayan states during 2022. It also covers relevant reports revealing gradual decline in power generation by hydro power projects amid growing concerns over physical and financial viabilities of new projects. There are also reports highlighting the looming climatic and geological threats over these projects. It is good to see that taking lessons from Chamoli disaster in Feb. 2021, NDMA has officially asked central govt not to rely on hydro power.
In previous parts of yearend roundups, we have covered (1) Dam induced floods & damages, (2) Fly ash dam breach incidents, (3) Impact of floods on Polavaram project, (4) People’s resistance against dams and hydro projects. Please see links for reports tracking hydro power projects related accidents and disasters in 2021 and 2020.

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.
