DRP 091126: Shift towards Weather Forecast based Dams’ Operation

A new study has again emphasized on why dam operations in India need to move from routine schedules to weather forecast based management. The study analyzed 223 dams across the country over 23 years by comparing river flows with and without the dams. Most importantly, the study has highlighted the limitations of dams in controlling successive floods. It found that about 74% of the dams were more than 90% full on the day of a high-flood event. Thus, leaving very little space to hold the next heavy rainfall spell and control resultant floods.

DRP 021126: Honestly assessing the impacts of Pump Storage Projects

Amid growing opposition to the proposed 3,000 MW Saidongar-I pumped-storage hydropower project in Karjat, Maharashtra, the most important question that needs to be asked is whether we are doing honest assessment of impacts of such projects. It may be remembered that these are not even location specific projects. A pump storage project does not have to come in the middle of western ghats, needing destruction of thousands of trees. Can these be called renewable energy projects or ‘clean’ without adequately assessing their impacts on forests, water sources, wildlife and local communities.

DRP 261026: Time to Prioritize Wetlands Conservation, Protection

The latest directions of the Supreme Court of India offer hope for wetland conservation but also raise serious concerns about the state of their protection. It is welcome that the apex court has recognized the water bodies as vital sources of drinking water and affirmed that their protection falls within the ambit of the fundamental right to life.

DRP 191026: India Disaster Management Must Shift from Response to Prevention

Two informative reports by Amal Chandra and Venkatesh Dutta in Down To Earth this week have once again highlighted serious gaps in India’s disaster management system. While our forecasting and response have improved in some cases, the number of disasters has also increased sharply. We often fail to understand the exact chain of events and remain reactive until the last moment. A key problem is that our system continues to focus more on response than prevention and lacks a holistic approach to disaster risk reduction.

The Budhi Gandaki river corridor in Nepal’s Gorkha district has witnessed a flash flood disaster causing extensive damage to public and private property. The flood reportedly began around 4:00 am on October 11, 2026, following the sudden breach of a landslide dam in a tributary of the Budhi Gandaki.

In a significant development last week, the Supreme Court has expanded its illegal sand mining case from the National Chambal Gharial Sanctuary to rivers across India. For over six months, the apex court has been hearing the matter and issuing directions to state governments of Rajasthan, Madhya Pradesh and Uttar Pradesh. However, the directions issued so far are yet to be fully implemented.

Marking the National Dolphin Day-Oct. 5, 2026-, this report highlights the deaths, threats and relevant developments concerning the national aquatic animal. In last one year, we have found reports of at least ten Gangetic dolphin deaths, including six in Uttar Pradesh, two in West Bengal, and one each in Bihar and Assam. The reported death toll is higher than in the previous two years, indicating continuing concerns over their survival.

DRP 051026: Drought: how prepared are we?

The DRP issue this week seems to have one central theme, connecting the various parts: Deficit monsoon leading to reduced reservoir levels, increased pollution, mass fish deaths and announcements of unprecedented droughts in more than one state. Since it was known to be a super El Nino Year and even IMD had predicted (though ratgher conservatively) deficit monsoon, the ultimate deficit of 12.6% in SW Monsoon rainfall may in fact seem like bit of a relief. This was largely thanks to unexpected above average rainfall in the wettest month of SW Monsoon, July, largely due to favorable Indian Ocean Dipole.

DRP 280926: Early Warning System important, but not a magic bullet

While writing about the landslide dam breach in Taiwan last year leading to 24 deaths, Dave Petley remarked: As always, the focus should be on vulnerability and resilience rather than only early warning systems (EWS). This is indeed worth emphasizing, underlining, highlighting. While early warning systems can be important and must be used wherever possible, it is not a magic bullet. It is one of the many other instruments in disaster management.

DRP 210926: Mismanagement at BBMB projects confirmed by CEA and Punjab

(Feature Image: The Tribune’s file photo of Pandoh dam)

The Central Electricity Authority has said in its report that there have been some serious operational and maintenance issues at BBMB’s Pandoh project, part of Beas Sutlej Link Project. In a separate development, Punjab government affidavit in the NGT has said that due to mismanagement at Bhakra-Pong dams, there has been avoidable flood disasters in Punjab in several years. Both developments confirm what we have said about role of BBMB projects in 2023 and 2025 floods in Punjab.
