Here we present the rainfall figures from India Meteorological Department in the just concluded month of June 2020, the first month of SW Monsoon 2020. The overall rainfall at all India level in June 2020 was 196.2 mm, 18% above normal rainfall in the month at 166.9 mm. It was 33% deficit last year.

This is India’s wettest June 12 years, The Times of India reported on July 1, 2020. Agriculture Ministry Data shows that sowing is 68% higher at 31.56 m ha. The June rainfall was 202 mm in 2008, the rainfall this year is the highest since then. All four IMD regions (Northwest, Central, South, East & NE) have recorded surplus rainfall, the surplus is the highest in Central (30.5% surplus) and E-NE (15.7%) regions. North West India had the lowest surplus at 3.5%. IMD Head Mrutyunjay Mohapatra said that whole of India was covered by monsoon on June 26, 12 days ahead of the normal date of July 8.

State wise rainfall Three states had large excess rainfall (above 60% surplus rainfall), namely Bihar, Madhya Pradesh and Sikkim. Eight states/UTs (Union Territories) had excess rainfall (20-59% surplus): Assam, Meghalaya, UP, Chhattisgarh, Maharashtra, Telangana, Andhra Pradesh & Andaman and Nicobar. Nine had deficient rainfall (20-59% deficit): Lakshadweep, Mizoram, Manipur, J&K, Ladakh, Himachal Pradesh, Delhi, Dadar & Nagar Haveli. Rest of India had Normal Rainfall.

Rainfall

State wise rainfall Pre Monsoon 2020 & Post monsoon 2019

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].

Open letter to MoEF & River Valley EAC: Review Recommendation to grant EC to Etalin HEP

The MoEF’s Expert Appraisal Committee (EAC) on River Valley Projects in its meeting in January 2017 recommended Environmental Clearance (EC) to the controversial 3097 MW Etalin Hydropower project in Dibang River Valley in Arunachal Pradesh. However, since the stage I forest clearance to Etalin HEP has not yet been accorded, the EC letter has not yet been issued. Hence there is an opportunity to stop EC to the project till the EAC reviews its decision.

It may be noted that Forest Advisory Committee (FAC) in its meeting on April 23, 2020, has decided in the context of Etalin Project: “As this is a large sized project in the Himalayas, inputs of IA (Impact Assessment) Division of the Ministry on whether environmental impacts of the proposed project and mitigating measures have been considered, will be obtained.” This provides an opportunity for the MoEF to direct the IA Division and EAC to review its decision to recommend EC to the Etalin Project.

Hydropower Performance

India’s hydro generation in 2019-20

In 2019-20 power generation from India’s large hydropower projects[i] was 11.26% of total electricity generation in India. In 2016-17, for the first time in independent India’s history, power generation from large hydropower projects in India fell below 10% of total electricity generation and remained below 10% for the next three years: 2016-17, 2017-18 and 2018-19. This calculation is based on actual generation (measured as Million or Billion Units[ii]) as reported by Central Electricity Authority (CEA) and not installed capacity (measured in Mega Watts).

DRP NB 27 April 2020: For whom is this unviable Etalin project being pushed?

In the ongoing debate on forest clearance for the controversial Etalin Hydropower project in Dibang Valley in Arunachal Pradesh between the Forest Advisory Committee, The Hindustan Times’s consistent reporting and Sanctuary magazine launching a campaign along with others, one (of the many) key question that remains unanswered is: for whom this economically (in addition to socially, environmentally and from climate change perspective) unviable, massively expensive project being pushed in a power surplus country?

Electricity from hydropower projects is no longer economically viable, since cheaper options are available. Some misguided people are claiming virtue in hydropower project claiming it provides peaking power. The fact is India is today not only power surplus, the peak power deficit has been just around 1% or less for long time. This when there is no attempt to either monitor as to how much of the electricity produced from existing hydropower projects provides peaking power, nor is there any attempt to achieve optimisation of operation of existing hydro projects to produce maximum possible hydropower. Nor is there any attempt to even manage the peaks either through pricing or other policy measures. In such a situation there is clearly no justification for more hydro for peaking. Moreover, the storage option is becoming increasingly cost effective, reducing the peaking power needs. So then for whom this project whose cost won’t be less than Rs 30000 crores at most conservative estimates, being pushed? The contractors, the equipment suppliers, the hydro lobby, the consultants, the timber lobby, the dam lobby, or the kickbacks?

44% above normal rainfall in Oct 2019 creates hopes for Rabi, Disaster for Kharif crops at many places

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 floods of Jiadhal River in Assam

Guest blog by Sazzad Hussain

Late Kartik Pegu, grandfather of Bipin Pegu of Jiadhal Chariali village under Dhemaji Revenue Circle of Dhemaji district in northeast Assam prepared his own burial site during early 1970s on the bank of Jiadhal River. The site, a paddy field, has been owned by the Patir family of the village near the railway bridge over the river. Kartik Pegu was buried there when he died in 1976 and a tombstone was built in his memory. After that in 1985 Bilapson Pegu, Bipin’s father, too was buried on the same site and another tombstone was placed in his memory close to that of Kartik Pegu. Now Bipin Pegu (47), a college graduate and a local peasant with three children wishes him to be buried on the same plot of land when he dies. But on the evening of 16 September, 2019, his wishes for final rest close to his near and dear ones were shattered when Jiadhal River suddenly surged with overflowing water submerging the tombstones of Bipin’s immediate ancestors. He has never seen them being under water so far. Continue reading “The floods of Jiadhal River in Assam”

CWC - Central Water Commission

Overview of CWC’s Flood Forecasting Sites 2019: North East India

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.
