District wise rainfall in June-Aug 2020 in India

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.

District wise Rainfall in India in June July 2020

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.

DRP NB 27 July 2020: China’s Three Gorges Dam may be safe for now, but at what cost?

International media has been full of stories this last few weeks, about the likely fate of the world’s biggest dam project: The Three Gorges Dam of China. The stories ranged from possible imminent threat of collapse of the dam to those from China that rubbished all such ideas. Part of it was fuelled by the World’s anti China mood due to the Covid and its expansionist activities including at Indian borders. But part of the reason was the difficulty to getting hard facts, since China does not have free media or democracy and suppresses any critical information. One direct evidence of this Chinese tendency was apparent when Reuters was the first one to publish on July 22, 2020, the story of a dam collapse in China on June 7, full 45 days after the event and even that story could not find any official to quote about the dam collapse. A more telling example of China’s tendency to suppress basic facts would be difficult to come by from recent times.

Delhi Drinking Water Canal gets toxic mix

In May 2019 SANDRP wrote, with photo evidence, after a visit to the Drain No 8 that brings Delhi’s drinking water that it is running next to drain no 6 carrying untreated industrial toxics from Haryana, with only sand bags separating the two. A visit on 21st July, 2020 provided video proof that water from drain no 6 is still happily mixing with drain no 8 at several places.

A visit to drain number 8, one of prominent canal carrying potable water supply of national capital can be shocking experience to anyone concerned with water quality and health of people. The canal (called escape) flows close to Delhi Haryana border in Sonipat district. The drinking water in the escape is being repeatedly contaminated with all sorts of industrial effluents.

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 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 archived. 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].

Augmentation canal breaches becoming new normal in Haryana

On May 17, 2020 the residents of Ranwar village in Karnal woke up to find their village surrounded by gushing water current which was fast entering their homes. The cause of the flooding was a breach[i] in augmentation canal running close to the village.

The incident was allegedly caused by a small hole at 60.200 point on left bank of the canal around 03.00 am gradually turning into a 40 to 50 feet wide breach by the noon same day. Before the local administration could get into action, around 250 acres of farm lands around the village was flooded.

Yamuna facing illegal, in-stream mining during lockdown

In April May 2020, local people and media reports have highlighted riverbed mining practices going on in the Yamuna river impacting river eco-system and riparian communities in gross violation of lock down norms during the Covid 19 crisis.

The first case is reported from Yamuna Nagar district, Haryana on April 30, 2020 by Times of India, where miners had created a bund across the river in the Gumthala-Jathlana area impending the natural flow of the river.

Are we ready to use more water from snow melt in Indus basin this year?

Union Water Resources Minister Shri Gajendra Singh Shekhawat has recently said that the snow this year on Himalayan peaks is the highest in 50 years, and reservoirs like Bhakra, Pong, Ranjit Sagar, Ramganga, Tehri, etc will receive very high water inflow from snowmelt during summer and SW Monsoon.[i] This is in fact the third warning this year on this issue. Earlier on Feb 27, 2020 and then again on May 4, 2020, the Bhakra Beas Management Board (BBMB) provided the same warning to its partner states. However, neither the Union Minister & BBMB, nor the partner states seem ready or doing anything to prepare for the unprecedented situation that the dams and rivers may bring in ongoing summer and coming SW monsoon.

In fact the situation is similar to the one that happened twice at Bhakra-Pong-Ranjit Sagar Dams last year[ii]. Even then not only there were massive floods, but the water flowed away to Pakistan, totally against the declared pronouncements and policy of Indian Government leaders including the Prime Minister.

Haryana Riverbed Mining 2019: Yamuna Robbed of Minerals, Flows

For past two years, large scale mechanized and illegal mining is happening in Yamuna River in Haryana state. The miners have created deep pits across the riverbed in Yamuna Nagar, Karnal, Panipat and Sonipat districts. Year 2019 has been a deficit monsoon year in Yamuna basin and the river had started shrinking unusually during October month. The rampant riverbed excavation has further robbed it of lean season flows. This detailed overview of river sand mining in Haryana in 2019 shows the severe impact of unsustainable and illegal mining practices on the river and villagers due to insensitive government and inefficient administration.
