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.
Ramganga (West) River originates from the western part of Dudhatoli reserve forest lying between Thailisain block in Pouri and Gairsain tehsil in Chamoli districts of Uttrakhand state. It is an important tributary of National River Gaga. The total length of the river is about 596 km. For first 200 km the river flows in Uttarakhand state and the remaining length falls in the state of Uttar Pradesh. Before it descends into plains, it is impounded by Kalagarh dam inside Jim Corbett National park.
The East and West Nayaar rivers[i] of Uttrakhand are small natural streams feeding the National River. They may meet the fate of Ganga and Yamuna, if the current trend damaging them remain unchecked. This pictorial report highlights the plight and beauty of East Nayaar river. The River is also spelt as NAYAR by a number of documents.
Degradation of Ganga river and its big tributaries gets adequate attention amongst concerned, while such small natural streams feeding the National River, largely remains absent in the mind and memory of stakeholders.
These perennial streams are making the River Ganga living and flowing in founding basin area. They seem healthy and living, however the problems of dumping of solid and liquid waste, construction debris, road cutting, water abstraction and hydro projects are rapidly catching up with the smaller streams.
Chandigarh is widely known for its well-designed urban areas and associated amenities. No doubt, the city is relatively congestion free and cleaner. The roads are wider, sideways have adequate space for walkers and cyclists and they are mostly covered under thick tree canopy earning its tag of ‘City Beautiful’.
However less is known about and rivers. This pictorial account tries to throw some light on present day situation of water sources like wells, ponds and rivers in and around Chandigarh town.

The following parts will present separate accounts for Rivers in North East, West, East and South Zones. There will also be separate review reports on Ganga & Yamuna rivers.
This week there are exemplary and encouraging wetlands revival stories from three metro cities of Chennai, Hyderabad and Delhi. In the first example from Hyderabad, meticulously chosen plant species such as tulsi, aswagandha, citronella and hibiscus have been used to create an artificial island to clean Neknampur Lake. The treatment islands are composed of four layers of which the bamboo base keeps the entire structure afloat. Based on soil-less hydroponics, these floating treatment wetlands absorb excess nitrates, thereby reducing the chemical content of the lake water. Microorganisms present in the wetland break down organic matter while the root systems filter out pollutants and sediments. https://www.thenewsminute.com/article/3500-saplings-floating-islands-help-rejuvenate-hyd-neknampur-lake-75819 (The News Minute, 3 Feb. 2018)
Similarly, Chennai-based Care Earth Trust along with the public works department (PWD) and the civic body has managed to restore three urban lakes. While many of the smaller wetlands have vanished over time, many mid-sized wetlands seem to have shrunk by almost 65 percent. Thanks to their joint effort, invasive hyacinth was removed from the Narayanapuram Lake in Pallikaranai, while sewer lines, which emptied into the Perungalathur Lake, have now been plugged. A detailed restoration proposal has been forwarded to the PWD regarding the Korattur-Madhavaram-Ambattur lakes. https://timesofindia.indiatimes.com/city/chennai/hyacinth-out-sewer-line-plugged-three-water-bodies-restored/articleshow/62748110.cms (The Times of India, 2 Feb. 2018)
Meanwhile, Delhi Jal Board (DJB) has taken up interesting new project of creating an artificial lake in Dwarka. The project will supply water in sub-city and improve ground water level too. DJB has approved Rs. 56 crore for the project which will be completed in next seven months. This would the first model project wherein a lake will be used to augment water supply. The special lake is being created next to the Dwarka water treatment plant (WTP) will have a sand bed to allow maximum percolation of water into the ground. It will have a capacity of 10 million gallons (MGD). The project is expected to add supply of 5-6 million gallons water to Dwarka every day.
In new year 2016, State Government of Uttarakhand must act against burgeoning amount of solid and liquid waste being put in Yamuna River in its home land.
River Yamuna appears flowing pollution and waste free in Himalayan stretch. But close observations go against this popular notion and paints grim picture of huge amount of waste finding its way in the river on a daily basis. This account highlights the issue in detail and urges State Govt. of Uttarakhand (UK) to take remedial actions before it is too late to reverse the degradation of the River.
Yamnotri is famous shrine and thousands of pilgrims and tourists frequent the place during Char-Dham Yatra held every year. These visitors, in absence of better options or for hygienic reasons prefer using bottled water, packaged foods (biscuits, snacks) and plastic disposals as food servings. As a result solid waste in massive amount is generated through the pilgrimage season which ultimately goes into the holy river. It’s worrying that this has become a norm for past many years.
