In the ongoing South West Monsoon, India received 44 year old high surplus rainfall of 327 mm in just concluded Aug 2020, 26.6% above normal rainfall of 258.2 mm. This helped the total June-Aug 2020 rainfall to achieve 10% surplus, with actual rainfall 780.3 mm, 69.9 mm higher than normal rainfall of 710.4 mm. In June the country received 18% above normal rainfall and in July it received 9.9% below normal rainfall, the rainfall at the end of June was just 1.1 mm above normal. Thus almost the entire surplus rainfall is thanks to the rainfall during Aug 2020. The rainfall distribution has however, been far from normal that these figures suggest, as we can see from the state wise and district wise figures below.Continue reading “District wise rainfall in June-Aug 2020 in India”
During the just concluded first half of the South West Monsoon 2020, India received 453.3 mm rainfall, just 1.1 mm above the normal rainfall of 452.2 mm during the period. The Surplus of 18% rainfall that India received in June 2020 has thus been wiped out by the 9.9% deficit in July rainfall. Normal rainfall in July 2020 is 285.3 mm, while actual rainfall was 257.1 mm. IMD does not provide monthly figures of rainfall for different states, sub divisions and river basins, which it should along with comparison with respect to normal rainfall and rainfall last year.
To get July 2020 rainfall, we will need to use the figures given in this article along with the figures of June 2020 rainfall (see: https://sandrp.in/2020/06/30/district-wise-rainfall-in-india-in-june-2020/). The district wise figures of June-July 2020 rainfall can be seen in this PDF file from IMD: IMD DISTRICT WISE RAINFALL FROM JUNE 1 TO JULY 31 2020.
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.

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 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.
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).

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?
Cloud burst incidents are on the increase across Himalayan states. The states of Uttarakhand and Himachal Pradesh have faced 23 and 16 cloud burst incidents in the south west monsoon 2019. This account compiles such reports from Jammu Kashmir (J&K) and north eastern Himalayan states.
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.

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”
