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.

The theme for World Water Day 2020 is ‘Water and Climate Change’. Indeed the changing climate has been altering the earth weather system including disrupting the water cycle.
Urban areas in India are facing increasingly severe water crisis due to mismanagement of available resources, urban flooding due to blockage and encroachments of drainage channels, pollution of water sources on account of increasing solid and liquid waste. However, there are individual, civil society group and government efforts which have been helping ameliorate the situation with rain water harvesting, pond revival, wells restoration among others. Here is a compilation of positive urban water stories from for World Water Day 2020.

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 first blog on just concluded South West Monsoon 2019, gave the national picture and broad picture of month wise, state wise, sub division wise and river wise rainfall. This blog provides some details of rainfall in districts of each of the 36 states and Union Territories (UTs) of India. Continue reading “Monsoon 2019: State wise rainfall”
Flood forecasting is an important activity during monsoon, considering the huge and increasing flood prone area, flood frequency, intensity and flood damages. Accurate and timely flood forecasting can hugely help reduce the damages due to floods. Central Water Commission (CWC) is the only agency responsible for flood forecasting in India. To understand the CWC’s flood forecasting better, we have compiled the list of the various flood, inflow forecasting sites and flood monitoring sites in India.
In this compilation, we have given state wise list of CWC’s flood forecasting, flood monitoring and inflow forecasting sites in North India, comprising of states of Jammu & Kashmir, Punjab, Haryana, Himachal Pradesh, Uttarakhand, Uttar Pradesh, Delhi and Chandigarh. It includes available details like name of river, sub basin, Warning level (WL), Danger Level (DL), High Flood Level (HFL), Full Reservoir Level (FRL), Maximum Water Level (MWL), as applicable. As we see below, there are many gaps in this basic information for the sites that are part of CWC’s list. A similar zonewise overview of CWC’s sites was compiled in 2018, which can be seen here. Overview of CWC Flood Forecasting Sites 2018: North India. We have brought this updated compilation for 2019 as there are large number of changes as ou can see.

On August 21, 2019, the first big flood spell of monsoon season 2019 has passed through Delhi. The river swelled to cross first warning level 204.00 metre and then danger level 204.83 metre at Old Railway Bridge (ORB) Delhi, finally receding from 206.6 metre which is 0.89 meter short of 207.49 Highest Flood Level (HFL) set in 1978.
The delayed and much awaited flood spell hit the city after highest ever recorded discharge of 8.28 lakh cusec water for two hours from Hathini Kund Barrage (HKB), Yamuna Nagar in Haryana on August 18, 2019 at 05:00 pm and 6:00 pm. The highest since the commissioning of HKB in 2000. The water release this year has also surpassed the discharge of 7.09 lakh cusec the previous highest discharge recorded at Taje Wala Barrage (TWB) during the highest flood recorded in River Yamuna in September 1978. The British era TWB barrage, some 6 kilometre upstream of HKB was washed away in 2010 floods.

The stretch of Yamuna River & its floodplain lying between Palla and Wazirabad Barrage in Delhi is still in reasonably good state. Though bisected by an embankment, the floodplain is free of too many recent major encroachments. The River keeps meandering between physical boundaries of Delhi and Gaziabad district of Uttar Pradesh on the other side. The average width of floodplain from embankment to embankment is 2 kilometres. The width of active river current varies from 200-300 metres.
Most parts of the floodplain on both sides of this embankment are under agriculture. The crops grown here includes paddy, vegetables and floriculture as cash crops apart from wheat, traditional riverbed crops of melons, cucumber, tomato and bottle guards etc. Use of chemicals is also growing. There is not much information available about the impact of chemical farming on floodplain and river eco system.

Chances are higher that you find a CETP malfunctioning on repeated visits for same commonly made lame excuses. (Feature image 4 MLD Kundli CETP discharging effluents without any treatment into drain number 6, while drain number 8 flowing next to it. Image taken on May 11, 2019 by author)
“Oh my God, its unbearable” was the first expression came out of my mouth instinctively and instantly, while standing at the outlet of Common Effluent Treatment Plant (CETP) in Sonipat District, Haryana. The plant was located in Kundli Industrial Area along DN (Drain Number) 8 at Delhi Haryana border. It was the morning of May 11, 2019 while observing status of DN 6, along with my friend Yayati Bhardwaj.
DN 6 carries industrial and domestic effluents from a large area of Panipat and Sonipat districts while DN 8 supplies potable water to Delhi via Yamuna river. Both drains run parallel for a length of 10 km and more than often intermix due to breaches and spill-overs. To know more about this, see: Delhi’s Drinking Water is 9 inch Wall away from Toxic Industrial Effluents & Sewage.

Role of Drain Number 8
About 300 cusec of water is supplied to Delhi via Drain Number (DN) 8. The drain branches off from Western Yamuna Canal (WYC) near Garhi Bindroli village in Sonipat. The total length of the drain is about 25 km. It carries Delhi’s share of water and discharges it into River Yamuna at Palla, where the river enters Delhi territory.
The water then flows 21 km downstream up to Wazirabad barrage where it is treated at Wazirabad Treatment Plant (WTP). This plant also supplies water to New Delhi Municipal Council (NDMC) areas which includes President House, Parliament areas among other prominent VIP residential units.

Fisher-folks know a river better than most others. Fish diversity is unfailing indicator determining river health. Unfortunately given the pollution load and lack of fresh flowing water, the Delhi stretch of Yamuna river is biologically dead. Hence fishing activities are rare and not much is known about the current fishermen community.
Situation was better in the past. Many people still fondly recollect, memory of bathing in a pristinely flowing Yamuna in Delhi around 1970s. They also describe their narrative of enjoying plenty of fish variety. Elderly in Greater Noida even claim watching ‘Sush’ dolphin in the river during their childhood.
Now the river is in continual degradation. It gets some clean water during monsoon, when adjoining areas face flood threat.
