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.

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.

Manipur DFO bans mining in Thoubal river Showing serious concerns to the degradation of the Thoubal River as well as its environment, a team of state police and Forest department officials led by District Forest Officer (DFO) RK Amarjit paid surprise visit at Moirang Purel and Itham area under Andro Assembly constituency where sand mining was underway at mass scale. During the inspection visit the govt official saw illegal excavation of soil from nearby hills of the area and dump it at Thoubal River for extraction of red sand.
As the mining of sand not only endangered the forest area of the surroundings but also degrades the condition of the Thoubal River, the DFO put immediate ban on the sand mining as well as excavation at hills of the surroundings. He also ordered ban on transportation of red sand in Thoubal and Kakching district. http://kanglaonline.com/2017/11/dfo-thoubal-swings-into-action-bans-sand-mining-at-thoubal-river/ (21 Nov. 2017)
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.
According to IMD, India is having normal monsoon this year, so far, as per rainfall till date (Sept 1, 2018). Against normal rainfall of 721.1 mm, India has received 676.6 mm rainfall, which is 6.2% below normal, considered within normal rainfall definition as per IMD. So India is having normal monsoon rainfall, says IMD. Let us check this against some ground realities.
However, East and North East India, one of the four regions for which IMD provides rainfall data, has so far had 27% below normal rainfall, while South India had 9% surplus rainfall. Thus, while at all India level, what seems all normal, is average of different, though serious departures from normal rainfall. Let us say this is first level of mirage of normal rainfall.

On Aug 5, 2018, SANDRP had uploaded blog[i] titled: “Overview of CWC’s Flood Monitoring & Forecasting in North East India”. CWC posted its 3-page reply to it around 7 pm on Aug 7, 2018.
Firstly, we welcome CWC’s reply to SANDRP blog. Here some responses to the content of what CWC has replied. Continue reading “Reply to CWC response on SANDRP’s article on CWC’s flood forecasting in NE India”
Central Water Commission (CWC) measures and monitors water level at 700 hundred Flood Forecasting site in the country. It publishes this information on its Flood Forecast 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.
As per the website 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.
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.
The River system in North East, other than the Brahmaputra, can be classified as the Barak River system and minor Rivers flowing to Bangladesh and Burma. The Barak River, Gumti River, Myntdu River etc are some of the major Rivers flowing to Bangladesh, while the Kaladan River, the Manipur River, Tizu River etc flowing in the States of Mizoram, Manipur and Nagaland are main Rivers flowing to Burma.
The Barak River basin covers parts of India, Bangladesh and Myanmar. In India it spreads over states of Meghalaya, Manipur, Mizoram, Assam, Tripura and Nagaland having an area of 41,723 Sq.km.
The Barak River originates from the Manipur hills, from Liyai Village in Senapati district in Manipur at an elevation of 2,331 m and flows through Assam and further down to Bangladesh, where it is known by the name of the Surma and the Kushiyara and later called the Meghna before receiving the combined flow of the Ganga and the Brahmaputra. The principal tributaries of Barak joining from north bank are the Jiri, the Chiri, the Modhura, the Jatinga, the Harang, the Kalain and the Gumra whereas the Dhaleswari, the Singla, the Longai, the Sonai and the Katakhal joins from south bank. The Barak sub-basin lies in the States of Meghalaya, Manipur, Mizoram, Assam, Tripura and Nagaland.
