On the World Fisheries Day, celebrated on Nov 21 every year, there is urgent need to focus attention on the well-being of one of the poorest and socio-economically weakest and much neglected section of population: Inland fisherfolks. They are in huge number, more than 2 crore directly dependent on inland fisheries, many others indirectly dependent. They, unfortunately have no voice in development discourse or decision making processes, nor any even in mitigation measures. Creating an inland fisheries policy, department and institute in every state and at centre can be an important step forward.

DRP NB 061123: Dam Disasters bring focus on Dam Safety Governance in India

Is the Dam Safety Panel (DSP) report dated Nov 1 2023 on Medigadda barrage on Gadavari in Telangana, a self-indictment of the Dam Safety Mechanism in India?

The report concludes: “it is construed that the I&CAD (Irrigation and Command Area Development) Dept. has nothing to submit about instrumentation data, pre-monsoon &post monsoon inspection reports, completion reports, quality control reports, condition of gates and many other inputs sought in the list therein”.

How and why did the NDSA (National Dam Safety Authority) allow such a state of affairs to continue for such an important dam that has huge implications for life and economy as the report itself says? What steps did the NDSA take before this disaster struck to ensure that all these basic dam safety measures were indeed in place and functioning? What is NDSA doing to ensure that all such basic steps and measures are in place at all the large dams in India? What did NDSA do to ensure that this dam, important from the point of view of life and economy, was also listed in CWC’s National Register of Large Dams? What has NDSA done to ensure that CWC’s National Register is indeed updated every year with inclusion of all large dams of India (Large dam as per its definition) and all their salient features? What has NDSA done to ensure that all Dam Safety information is in public domain promptly?

Dam Disaster

Medigadda dam of Kaleshwaram project in Telangana damaged in Oct 2023

October 24, 2023November 3, 2023 SANDRP1 Comment

A portion of the Lakshmi (Medigadda) barrage on Godavari river on Telangana-Maharashtra border, part of the Kaleshwaram Lift Irrigation Project (KLIP) in Telangana’s Jayashankar Bhupalpally district[i] caved in on Oct 21 2023, Saturday night with a loud sound. The incident led to the temporary closure of the bridge of the barrage across the Godavari River that links Telangana’s Mahadevpur mandal with Maharashtra’s Gadchiroli district. The KLIP is the world’s largest Lift Irrigation Project, possibly the costliest, with expenses already above Rs 1 lakh crore. The Union Govt, recognising this as a major dam failure under para 8 of Schedule II of Dam Safety Act 2021, has promptly sent a team of six experts to assess the damage.

DRP NB 231023: Need to be a little serious about Dam Safety, Flood Forecasting, Use of Early Warnings

October 23, 2023 SANDRPLeave a comment

India need to relook the Dam Safety Act Experts say the Sikkim incident exemplifies blind spots in both legislation and implementation. The DSA does not promote risk-based decision-making and fails to incentivise transparency. Himanshu Thakkar, an environmental activist and coordinator of South Asia Network on Dams, Rivers and People, says that the frequency and scale of such disasters reveal a pattern of neglect: “It keeps happening regularly, people face disastrous consequences and we call these ‘natural disasters’. But there’s nothing natural about them.”

A robust DSA should allow different stakeholders to access information easily, but India’s framework falls short. “Dam safety is a public purpose function. Everything about dam safety, functions of all the institutions and committees and authorities, their reports, decisions minutes and agendas, everything should be promptly available to the public,” says Mr. Thakkar. “But nothing is in the public domain.” He adds that transparency is further obstructed when national and State bodies comprise government employees and engineers who worked on these projects, compromising objective decision making and lacking “people with a proven track record of taking independent decisions.”

DRP NB 161023: Kaddam Dam Rehabilitation in Telangana: Many more will need this

Telangana’s Kaddam Dam, built with inadequate spillway capacity, has seen multiple threats and disasters over the years, starting from the very first year after its commissioning in 1958. The dam again saw threat of being washed away during monsoon this year. The Telangana government has decided to rehabilitate the dam at a cost of Rs 640-700 Cr, by reconstruction of spillway and installation of new gates. We hope the new spillway capacity will be in line with the changed monsoon rainfall pattern and will be able to take care of the higher probable maximum precipitation and higher probable maximum flood. Though we are unlikely to get to know how this is going to happen, as the standard operating procedure of all dam owners in India is secrecy rather than transparency even in dam safety aspects. One also hopes this is done at the earliest, and till that is achieved, the dam rule curve will be changed to ensure the dam does not face disastrous situations during monsoon.

Dam Safety Act & the role of Dams in the 2023 HP Floods

October 11, 2023 SANDRP8 Comments

In order to have high standards of dam safety the prerequisites are designing and constructing dams with reasonable safety margins; operating and maintaining them safely; and having emergency arrangements to address situations that might arise. Operation of dam within its ambit also includes thorough understanding of likely impacts and its management in case of flooding, in any emergency situation or in the event of dam failure, both upstream and downstream on communities living there, their livelihoods and also on infrastructure and property which can get affected. In fact in many countries like Sweden and in many states of the USA, a dam is assigned a dam safety class i.e. A, B or C depending upon the significance of the damage that might occur in case of dam failure, class A being assigned to dams whose failure might cause significance loss of public life and property. Dam safety requirements are calibrated accordingly and a higher burden is put on dam owners of higher class, concerning safety management system, emergency plans, overall assessments, and annual dam safety reporting.

Dam Disaster

Glacial Lake FLood destroys Teesta-3 Dam in Sikkim, brings wide-spread destruction

October 4, 2023November 7, 2023 SANDRPLeave a comment

A Glacial Lake Outburst Flood (GLOF) that originated at South Lhonak Glacial Lake at around 00.40 hours on Oct 4, 2023, washed away the 60 m high dam of Sikkim’s biggest hydropower project, the 1200 MW Teesta 3 HEP. The flood has brought unprecedented disaster all along the river in Sikkim and further downstream in W Bengal and then Bangladesh. Central Water Commission (CWC) reported early in the morning of Oct 4 that there was cloud burst at the site of the lake burst, the cloud burst could have played the role in triggering the lake burst.
