Maharashtra Upper Krishna Basin Flood 2019 Vadnere  Committee-2: A report with “difference”!

Guest Blog by Pradeep Purandare

SANDRP published my article entitled “Maharashtra Floods 2019: Don’t waste the crisis” on 26th May 2020.In that article I had explained the reasons behind my resignation from the Flood Study Committee. Exclusion of my chapter from the committee’s report was one of the reasons. Now, the said report is available in public domain & surprisingly enough, it includes my chapter; thanks to SANDRP!

In this note, I would like to draw the attention of all concerned towards the erroneous data, strange analysis & weird logic employed by the Vadnere Committee-2 in its report without discussing the serious issues in the committee meetings.

Maharashtra’s Upper Krishna Basin again faces prospects of Dam Floods?

Seven major dams with high storage capacities in Upper Krishna Basin in Maharashtra’s Satara and Sangli districts have huge 1422.12 Million Cubic Meters (MCM) water in live storage as on May 30, 2020, just about a week away from the prospects of beginning of monsoon. The Wadnere committee’s efforts not withstanding, there is no doubt that almost simultaneous water release from these seven dams played a major role in creating highest ever flood levels in Maharashtra’s Upper Krishna Basin in August 2019. Though on this day last year, these seven dams had much lower water in live storage at 556.49 MCM, the almost simultaneous water release from these dams hugely contributed to the unprecedented flood disaster in Sangli district last year. With 256% water in live storage this year compared to last year on this date, the risk of these dams contributing to flood disaster in Sangli district is even greater this year. Unless the authorities in the water resources department, district administration and disaster management authorities wake up and ensure that these dams help moderate rather than contribute to floods.

Maharashtra Floods 2019: Don’t waste the crisis

Guest Blog by Pradeep Purandare

Abstract: Flood Study Committee in Maharashtra has set up a record of sorts by not only denying technical information to its member but even excluding his chapter altogether from the final draft report. The humiliated member who opted to quit the committee shares his experience in this article. The article highlights: (1) the report was finalized without detailed discussions on all chapters together, (2)  Maharashtra is well equipped with theory of ROS (Reservoir Operation Schedule) & Flood Zoning but doesn’t implement the same,  (3) Maharashtra wasted full 13 years by not implementing the recommendations of Wadnere Committee-1 regarding revised ROS & integrated reservoir operation,  (4) Total absence of flood management governance & (5) most importantly, the simulation study carried out by the committee indicates that backwater effect of Almatti project is not responsible for Maharashtra floods 2019. Next, the paper explains WRD’s (Water Resources Department) viewpoint regarding Maharashtra Floods 2019 & its emphasis on structural measures.  The paper then points out WRD’s strange policy, raises questions regarding reliability of discharge measurement at observation points & makes following critical comment on Reservoir Operation.

“There is, therefore, room to believe that had there been the implementation of revised ROS as recommended by Wadnere Committee -1, less storage in the dams in the last week of July 2019 & staggered outflow from 9 projects based on  the principle of integrated ROS, the flood situation would have been different & comparatively speaking less severe.”

In the end, the author requests the govt to follow the principle – “Don’t waste the crisis” and

  • Take a critical review of the State’s preparedness regarding Flood Moderation
  • Adopt & Implement the concept of Integrated Reservoir Operation
  • Don’t make compromises in respect of flood zoning
  • Ask Wadnere Committee-2 to make amendments in its report & modus operandi as well.

Open Letter to Kerala Chief Secretary about Monsoon preparedness and disaster risk reduction

On May 7, 2020, a number of groups in Kerala wrote this letter to Kerala Chief Secretary on the important issue of Monsoon preparedness and Disaster Risk Reduction, with particular focus on Reservoir operations during Monsoon. This is an excellent initiative worth emulating by a lot of us in different states and at national level. Hence we are happy to Share this here with permission from the authors.

Sir,

The South-West monsoon is scheduled to arrive at Kerala by around June 1st. Early predictions on the monsoon by different agencies including the Indian Meteorological Department (IMD) suggest normal to above normal rainfall in India. The South-Western coast and adjoining regions are expected to get very good rainfall this year. It may be recalled that the state had to face extremely high-intensity rainfall incidents and consequent disasters in the last two years. Hence, the state needs to be well prepared to face any eventuality during the coming monsoon. The following concerns may be addressed and suggestions may be considered.

Are we ready to use more water from snow melt in Indus basin this year?

Union Water Resources Minister Shri Gajendra Singh Shekhawat has recently said that the snow this year on Himalayan peaks is the highest in 50 years, and reservoirs like Bhakra, Pong, Ranjit Sagar, Ramganga, Tehri, etc will receive very high water inflow from snowmelt during summer and SW Monsoon.[i] This is in fact the third warning this year on this issue. Earlier on Feb 27, 2020 and then again on May 4, 2020, the Bhakra Beas Management Board (BBMB) provided the same warning to its partner states. However, neither the Union Minister & BBMB, nor the partner states seem ready or doing anything to prepare for the unprecedented situation that the dams and rivers may bring in ongoing summer and coming SW monsoon.

In fact the situation is similar to the one that happened twice at Bhakra-Pong-Ranjit Sagar Dams last year[ii]. Even then not only there were massive floods, but the water flowed away to Pakistan, totally against the declared pronouncements and policy of Indian Government leaders including the Prime Minister.

2019 Monsoon: Instances when Dam Safety Came into Question

The South West Monsoon in 2019 in India brought the highest rainfall of last 25 years and issues related to heavy rainfall continue even to the end of October 2019. Here we have listed major instances during the monsoon when there were question marks over safety of dams either due to structural safety or due to wrong operations of the dams. Some issues of breaches of embankments/ canals are also included here. As we can see, the instances come from across the country, including North East, North, West, Centre, South.

Man made National Crisis at Gandhi Sagar Dam in Sept 2019

Its not everyday that Government of India’s National Crisis Management Committee (NCMC) meets. It’s even rarer when the NCMC meets to deal with issues related to a dam. And that too on a Sunday.

The National Crisis So when on Sunday, Sept 15, 2019, the Cabinet Secretary chaired the NCMC meeting[i] to discuss the issues surrounding the Gandhi Sagar Dam on Chambal river in Madhya Pradesh (close to Rajasthan border) and called it a National Crisis, it signified how serious was the situation.

Unprecedented Dam flood situation in Uttara Kannada in Aug 2019

The New Indian Express published a most remarkable report on Aug 24, 2019[i]. It said, among other things: The district administration of Uttara Kannada will seek an inquiry report from the managing director of Karnataka Power Corporation Limited on untimely release of water from Kadra dam to Kali River, which caused flood in Kadra, Mallapur, Kaiga township, Hanakon, Kharge Jooga island, Kinnar, Siddar, Vailawada and many villages in Karwar taluk in the first week of August. 5,000 people from these villages were shifted to rehabilitation centres in Karwar and other villages. Half of the Kaiga township was inundated and employees of Kaiga Atomic Power Station had to use boats to reach the nuclear power plants… The district administration was not informed about the increasing inflow into Kadra dam and outflow into the river. Finally, DC Harish Kumar K, ZP CEO M Roshan and then SP Vinayak Patil camped in Kadra and took over the control of the dam due to the failure of dam officials. They managed the outflow of the dam for a couple of days. Deputy Commissioner Harish Kumar K said the district administration will write to KPCL MD seeking an inquiry on water released from dams to Kali river.” Continue reading “Unprecedented Dam flood situation in Uttara Kannada in Aug 2019”
