Dams Floods 2018: Filling up Dams well before Monsoon end, Invitation to Disaster

The tendency of filling up reservoirs in the beginning and middle of monsoon season have been leading to avoidable flood disasters in the country. Apart from Kerala flood 2018, which was aggravated by mismanagement of reservoirs, various reports show that reservoirs in river basin of Cauvery, Krishna, Godavari and Ganga were also filled up well before the end of South West monsoon season. Resultantly there were many man made flood spells in downstream areas affecting lives and livelihoods of people.

After highlighting role of dams in floods in Kerala and how improper dam operation affected people in Assam and Himachal Pradesh, this third and concluding part throws light on other dam induced flood (and canal breach) incidents in 2018.

HFL crossing flood events during India SW Monsoon 2018

Even as the rainfall during South West Monsoon of India during June Sept 2018 was 9.4% below normal, a number of HFL (Highest Flood Level) crossing flood events were recorded on CWC’s (Central Water  Commission) Flood Forecasting (FF) website[i]. Since CWC’s FF site does not provide archived information or comprehensive list of such events, we are here putting together a list of such events that we had noted during the SW monsoon, for future records and also understanding trends of high floods.

Monsoon 2018 Overview: Serious Anomalies Hidden by Macro Figures

2018 becomes fifth year in a row when India’s south west monsoon has been below normal.  In the beginning of monsoon season, Indian Meteorological Department (IMD) has forecasted rains to be normal with rainfall equal to 97 percent of the long term average. However at the end of the season the overall rainfall turned out to be 91 percent, with deficit of 9 percent at national level. However, as we see in this overview, the situation as move from national to local figures, is much different, mostly much worse.

According to IMD’s State Rainfall Map (cumulative) dated 30 Sept. 2018, the country received 804.0 mm rains against 887.5 mm of normal average. Thus the south west monsoon 2018 had 9.4 percent below normal rainfall.

DRP News Bulletin 29 October 2018: Better Paddy Options Exist For Punjab

A try-out of the technique to grow paddy without puddling at village Chehlan of Ludhiana has resulted in higher yield in comparison to puddled fields, while saving water in the process. The crop was ready for harvest days before expected time, saving irrigation water otherwise to be used for another fourteen days. This trial was funded and supervised by ATMA, a central govt.  scheme under the Union Ministry of Agriculture.

Puddling is a traditional method of flooding paddy fields with running water, whereas in non-puddling technique, ‘ridges and furrows’ are formed in soil to let water store in spaces and let it stay, thus reducing irrigation frequency.

“Not paddy but puddling is the enemy of waters of Punjab. It is wastage of water to puddle fields as most of it just evaporates. We have saved 45-50 per cent of water in non-puddled fields. Our yield has been almost 30 per cent more from fields where crop was not puddled. Also, non-puddled crop matured very early, saving at least ten days of irrigation water,” says Rupinder Singh Chahal (43) who along with his brothers Jasvir Singh (48) and Kulwinder Singh (52) experimented with ‘non-puddling’ technique on four acres this year.

INDIA: Overview of CWC Flood Monitoring Sites

Central Water Commission is the only agency doing flood forecasting in India. As per CWC’s Flood Forecasting website[i] the Data Flow Map has information about 226 Flood Forecast Sites in the country comprising of 166 Level Forecast Sites and 60 Inflow Forecast Sites. It also monitors 700 Flood sites, information made available through List Based Exploration and Hydrograph View, but no flood forecasting is done for these sites.

In order to better understand the CWC’s flood monitoring and forecasting work, SANDRP has published report of CWC’s Level Forecast, Inflow Forecast and level monitoring sites in 5 zones of North India[ii], North East India[iii], East India[iv], South India[v] and West India[vi].  Through this report, we have presented all the data at one place with links to separate zone wise reports with detailed description.

Cauvery is facing very serious flood risk, but CWC is in slumber

(The figure above is screen shot of CWC Flood forecasting site showing no warning signs even at 5 pm on 230718)

Almost all the big dams in Cauvery Basin are full on the earlier ever monsoon date this year. This includes Krishnaraj Sagar, Mettur, Kabini, Harangi, Hemavathi and Bhavanisagar. They are almost full and have started releasing large flows to the downstream areas. This is when we are past just about six weeks of South West Monsoon, the North East monsoon would come after that. It means that the basin is facing major risk of floods in next 2-5 months. And yet Central Water Commission, India’s flood forecasting agency, seems to be in deep slumber. It has not even bothered to update the flood readings on its designated sites from the 2017 figures.  Continue reading “Cauvery is facing very serious flood risk, but CWC is in slumber”

Supreme Court Judgment on Cauvery Dispute: Does it change anything?

Supreme Court of India passed the much awaited 465-page Judgment on Cauvery Water Dispute on Feb 16, 2018[i]. After the Cauvery Water Disputes Tribunal declared its award on Feb 5, 2007, a number of Appeals were filed in the SC, challenging the Tribunal Award, including those by Karnataka and Tamil Nadu. By this Judgment, the SC has partially allowed the Karnataka Appeal (Civil Appeal 2453 of 2007) and disposed off all the appeals. The Award was published in gazette only in 2013, following an earlier SC order. The SC Judgment provides additional 14.75 TMC (Thousand Million Cubic Feet) of water to Karnataka and thus reduces Tamil Nadu’s share to that extent.
