District Wise rainfall in India in June 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.

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].

DRP NB 18 May 2020: Signs of Impending Dam Floods in SW Monsoon 2020?

These are rather ominous signs. As per the latest reservoir storage bulletin of Central Water Commission dated May 14, 2020, the 123 reservoirs monitored by CWC has massive, 64.6 BCM (Billion Cubic Meters) in live storage capacity, which is about 165% of the capacity on same date last year and average of last ten years, even as monsoon is just weeks away. Most dams known to create DAM INDUCED FLOODS in the past, including Bhakra dams (we wrote about it earlier this month: https://sandrp.in/2020/05/07/are-we-ready-to-use-more-water-from-snow-melt-in-indus-basin-this-year/), Narmada dams, Odisha and W Bengal dams (Cyclone AMPHAN is going to bring a lot of water here in next few days, even before the monsoon), Krishna basin dams, Cauvery basin dams, Bansagar and Gandhi Sagar Dams, and Kerala dams among others. All these dams have above average storage situation.

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?

DRP NB 20 April 2020: Solutions to Covid 19 & Climate change are same?

This proposition clearly sounds simplistic and seems devoid of science or logic. But the case studies of the epidemics since 1980 and loss of forests, biodiversity and sustainability shows that this is not to be dismissed that easily. In fact the following interview with Dr Aaron Bernstein makes a powerful case to show why this indeed has a lot of science and logic behind it. It also hence makes a case that yesterday (our “normal”), is no longer a good model for better tomorrow.

IMD’s 1st Long Range forecast for SW monsoon 2020

IMD’s 1st Long Range Forecast for SW Monsoon 2020 on Apr 15, 2020[i] says:

– Rainfall will be normal (100% of LPA: Long Period Average of 88 cm). IMD says Neutral El Nino Southern Oscillation prevails in Pacific Ocean and Neutral Indian Ocean Dipole conditions prevail in Indian Ocean, likely to remain throughout the monsoon as per most models, some indicate weak La Nina conditions in Pacific Ocean in second half of monsoon.

– FORECAST BASED ON MONSOON MISSION COUPLED FORECASTING MODEL There is high probability (70%) of monsoon rainfall being above average to excess (over 104% of normal)

– FORECAST BASED ON OPERATIONAL STATISTICAL ENSEMBLE FORECASTING SYSTEM: 9% probability of Deficient monsoon (Over 10% below normal); 20% probability of below normal (90-96% of normal) rainfall; 41% probability of normal monsoon (96-104% of normal rains); 21% probability of above normal (104-110% of LPA rains) and 9% probability of excess (over 110% of normal) rains.

DRP NB 2 March 2020: Will Mumbai rise up against unwanted, destructive Gargai Dam?

Mumbai Metropolitan Region (MMR), with annual rainfall in access of 2000 mm, does not do much to harvest the rain. It does not protect its local water bodies. It does not recharge groundwater to the extent it can easily do. It does not reduce its transmission and distribution losses. It does not treat its sewage to recycle and thus reduce freshwater demand. It does no demand side management. And yet it keeps demanding more water, and for that building of more dams and thus pushing more destruction. Without any credible options assessment. It has no water policy or water vision for smart water management.

The proposed Gargain Dam that will lead to destruction of over four lakh trees in 720 ha forest mostly in Tansa Wildlife Sanctuary, is a good example of how Mumbai is fuelling such dam building and destruction. The Rs 3105 Cr project will have many other impacts, including displacement of tribals and destruction of livelihoods for thousands others. As SANDRP report showed six years ago, (https://sandrp.in/2013/12/20/dams-in-tribal-areas-of-western-ghats-for-water-supply-to-mumbai-why-are-they-unjustified/, https://sandrp.in/2013/12/18/multiple-dams-for-mumbai-region/) and as our letter to the then Maharashtra Chief Minister emphasised in 2015 (https://sandrp.in/2015/01/13/water-smart-mumbai-open-letter-to-cm-devendra-fadnavis/), MMR region does not need any of these dams.

It was good to see MID DAY news paper report and EDIT highlighting some of these issues. Will the people of Mumbai Rise up, to stop this destructive dam, being pushed in their names, the way they stood up to save the far fewer Aarey Milk Colony trees?

Cloud Burst

Uttarakhand Cloud Bursts in Monsoon 2019: No Doppler Radars Six Years Since 2013 Disaster

With the beginning of south west monsoon season 2019, many Himalayan states started witnessing exceptional rainfall events known as Cloud Bursts. The extreme weather event – like previous years- caused large scale destruction in ecologically sensitive and remotely located vulnerable hilly areas. This account compiles the available information about such incidents in Uttarakhand in 2019 SW monsoon.

DRP News Bulletin 9 Dec 2019: CITIZENS REPORT ON WHAT AILS GANGA REJUVENATION

 The Hindustan Times editorial on Nov 27, 2019 has rightly said the following about “a recently-released Rejuvenating-Ganga River – A Citizen-Report, by the India Rivers Week, a consortium of seven NGOs”.

“A key reason for the failure of the river cleaning projects (Ganga and Yamuna action plans), says a recently-released citizen’s report, Rejuvenating Ganga,by the India Rivers Week, a consortium of seven NGOs, was their single-point focus on the main stem of the river, while the Ganga basin actually has eight major rivers (Yamuna, Son, Ramganga, Gomti, Ghaghra, Gandak, Kosi and Damodar). The majority of the funds were spent on pollution-abatement measures on the main stem of the Ganga and on the upper Yamuna basin, which constitute just 20% of the Ganga basin.”

River Wise Rainfall in Monsoon 2019

Indian media never seems to report this, but IMD (India Meteorological Department) also provides river basin wise rainfall figures for South West Monsoon, also for other seasons. As in the previous years, here is an overview of the river basin wise rainfall during just concluded SW Monsoon 2019 (June-Sept 2019, though the monsoon started withdrawing only on Oct 9 and has not yet fully withdrawn from across India as I write this on Oct 15 2019), like the way we have been doing for the last three years[i]. Our earlier monsoon 2019 articles provided monsoon over view[ii], state wise rainfall figures[iii] and Marathwada specific situation[iv].

It’s not clear why Indian media does not report river basin wise rainfall figures, since that is arguably, the most appropriate way to look at the rainfall figures, since river basins are the hydrological units and the run off from the rainfall ends up in the rivers, and creates floods many times, as happened during 2019 monsoon. There could be issues of quality of the river basin wise rainfall figures, but that is true for all IMD’s rainfall figures at some level or other.
