IMD is happy to declare a monsoon as normal as long as total quantum of rainfall at national scale is within 4% of what is defined as normal monsoon rainfall during June 1 to Sept 30. Even if this means there is spatially or temporally or both spatially & temporally, the total rainfall or its distribution is abnormal in large parts of the country. It was good to see a national newspaper, asking question if the monsoon is normal even though it’s not temporally normal as was the case in large parts of the country this year.
The IMD normal only assures meteorological normal of national monsoon rainfall within given period. It does not assure hydrologic normal nationally or in different parts of the country, nor agricultural normal rainfall nationally or in different parts: sub divisions, states, river basins, districts, talukas/ tehsils or villages and wards. We clearly need much more realistic and nuanced definition of even meteorological Normal monsoon rainfall, which IMD needs to work on. But as far hydrological or agricultural normal rainfall is concerned, both temporally and spatially, those concerned outside IMD will need to work on.

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.

- Hon’ble Mr. NarendraModi,
Prime Minister of India,
2. Hon’ble Mr. Nitin Gadkari,
Minister, Water Resources and Ganga Rejuvenation Ministry,
Government of India.
3. Hon’ble Mr. Trivendra Rawat
Chief Minister, Uttarakhand
Subject: River Ganga
There is no debating that Ganga must flow free or will perish with all attendant consequences. This is vindicated by Ravi Chopra Committee in its report to the Supreme Court submitting that there has been an increase in disasters in Uttarakhand ever since the tragedy in 2013, due to the presence of big dams. The Union of India under your governments pledged to rejuvenate the Ganga including Alaknanda, Mandakini and Bhagirathi and all their tributaries.
Presently, four under-construction dams namely Tapovan-Vishnugad, Vishnugad-Pipalkoti, Singoli-Bhatwari and Phata-Byung are further threatening the survival of this river adding to the damage already done by the existing dams.
To save the River Ganga, Swami Saanand fasted for 111 days to draw your attention to River Ganga’s cries for survival before he succumbed unheeded. Carrying on the baton, Sant Gopaldas fasted for 146 days when he disappeared under suspicious circumstances unheard and unheeded. Presently the 26 year old young Brahmachari Aatmabodhanand from Matri Sadan, Haridwar, has been on a fast since 24th of October 2018 determined to carry on the baton for a positive response on Ganga from your governments.

As this report narrates, a great volunteer effort is underway in Mumbai to clean up Mithi river. What they have achieved is just about 350 m of clean river, after labouring over weekends for several months. But this is such a daunting task to even venture to start. They have not only started, but made visible progress. Let us hope it will achieve all its objectives.

In its latest report, the National Green Tribunal (NGT) appointed monitoring committee overseeing Yamuna River cleaning progress in Delhi says that the river is “fighting to stay alive” and it would not be possible to rejuvenate the Yamuna unless minimum environmental flow is provided as it is “virtually reduced to a trickle and remains dry in some stretches for almost nine months of the year”.
In the action plan, it is mentioned that “Although the Yamuna river flows only for 54 kilometres from Palla to Badarpur through Delhi, the 22 km stretch from Wazirabad to Okhla, which is less than 2 per cent of the river length of 1370 km from Yamunotri to Allahabad, accounts for about 76 per cent of the pollution level in the river”.
The committee has suggested that a team of scientists be formed from CPCB, DPCC and other institutions like IIT Delhi or NEERI to carry out inspections and submit reports to it for remedial action. The team can look into the risks and benefits of an alternative way of routing the same quantity of water which can help in reducing the pollution level, it said.
The monitoring committee also raised objection to the capacity utilisation of common effluent treatment plant (CETP) which is as low as 25 per cent. There are 28 industrial clusters in Delhi and 17 of these are connected to 13 CETPs. The remaining 11 clusters are not connected to any CETP. Another area of concern is the direct discharge of completely unregulated waste from industries and residences into the river.

With an area of little over 200 sq kms, Nagpur, the geographical centre of India, is a lucky city to have 11 lakes and two rivers within municipal limits. Nag Nadi – which lends its name to the city – is the main river along with the other, Pili Nadi; the two later merge and further join the Kanhan river near the city outskirts.
It has always been believed that the river starts as an outflow from the western weir of Ambazari Lake in west Nagpur. In 1998, a bunch of researchers went to further explore the catchment of the lake and found the actual origin of the river is up north of the lake at a place called Lava, more than 25 kms from this western weir.
