This photo is possibly the worst advertisement for a hydropower project with landslide rocks sitting on top of the dam. A massive landslide has severely damaged the 55 m high dam of the 510 MW Teesta Hydropower Project of NHPC, at 00.20 hours on June 27, 2020. This is a major blow to NHPC, considered India’s premier hydropower company. It’s also a major blow to the propaganda of International Hydropower Association, falsely pushing this very project as an example under IHA’s Hydropower Sustainability Assessment Protocol[i].
NHPC PR on June 28 afternoon said the landslide happened “at Dam Axis on left abutment hill side from a height of about 40 meter from Dam top NHPC Teesta-V Dam at Dikchu, East Sikkim. The access to Dam Control Room (DCR) as well as electrical connection to Dam top was cut-off due to this slide.” The electricity supply was restored about 9 hours later.

India Meteorological Department (IMD) divides a water year (June 1 to May 31) into four seasons: Monsoon: (June 1 to Sept 30), Post monsoon (Oct 1 to Dec 31), Winter (Jan 1 to Feb 28/9) and Pre Monsoon (March 1 to May 31). For rainfall during all these seasons, IMD’s hydro-meteorological website[i] provides a lot of data on daily basis, including daily district wise rainfall, state-wise, sub division wise and river wise daily rainfall maps among many other weekly, monthly and seasonal products. However, one problem with it is that none of this information is achieved. So if you missed seeing or downloading available data on any date, there is no way to look at it even next day. This is even true of the seasonal rainfall maps, unfortunately.
Most observers look at the monsoon rainfall data, which is clearly the most important season, without doubt. However, the rainfall in other seasons is also very important from a number of perspectives.
Here we are giving a detailed account of the pre-monsoon season rainfall that India received in the season just ended on May 31, 2020, including state wise, sub division wise, river wise and also district wise figures. Along with it, we also provide the figures of post monsoon figures for the just concluded water year. For the winter season (Jan-Feb 2020) we have only the figures for Jan 2020 since we missed downloading the Feb 2020 figures. We had already provided the monsoon 2019 figures through two blogs in October 2019[ii].

The Oct 2019 rainfall all over India was 109.7 mm, 44% above normal expected rainfall of 76 mm, following 53% above normal in Sept 2019. The rainfall this month has been unusual and has had some major impacts. One of the reasons has been that the SW monsoon withdrawal continued well into Oct 2019, when it almost always gets over by the end of Sept. There were also several cyclonic circulations and depressions mostly from Arabian sea.

The first blog on just concluded South West Monsoon 2019, gave the national picture and broad picture of month wise, state wise, sub division wise and river wise rainfall. This blog provides some details of rainfall in districts of each of the 36 states and Union Territories (UTs) of India. Continue reading “Monsoon 2019: State wise rainfall”
Central Water Commission (CWC) monitors water level at several hundred sites in the country during monsoon every year. It publishes this information on its Flood Forecast (FF) website[I]. The website has three ways to get this information: Data Flow Map, List Based Exploration, and Hydrograph view. The Hydrograph view provides information for past 72 hours, supposed to be updated every hour. This is in addition to the list of current forecasts.
The CWC’s FF website had in 2018 monsoon, 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. As reported below, the number of sites have gone up during 2019 monsoon, which is welcome. However, most of the new sites, along with some old ones do not have key information.

“Everybody loves us Lepchas” said Tseten. He went on to explain that this affection was important to the Affected Citizens of Teesta and was a major reason that the group decided never to add violence[i] to their arsenal of techniques in their fight to save the Teesta.
The idea of non-violence being a strategic decision rather than a (purely) moral one intrigued me. I was at a meeting where several anti-dam activists from the North-Eastern states were present. As I listened to their stories, it was clear that these veterans had several lessons for those of us worried about the death of their rivers today. Each of the groups that had been compelled to fight for their rights had evolved strategies and developed tools to help them.
Sadly, the struggle against ‘development’ projects that adversely impact the lives and livelihoods of people, as well as cause irretrievable harm to the environment, continues in many places across the world. Rather than reinventing the wheel, it will be useful for young activist groups to have access to the lessons learnt by those who have preceded them.

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.

In order to better understanding the CWC’s flood monitoring and forecasting work, in this article we have given state wise list of CWC’s Level Forecast, Inflow Forecast and level monitoring sites in North East India. For better understanding, we have also included part of West Bengal that is in Brahmaputra basin here, in addition to the 8 North Eastern states. Similar report has been published for North India[II] and we hope to publish reports covering other regions of India too.
