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.

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.

On April 11, 2019, is the birthday of Yamuna river. The Yamuna Jayanti comes every year on the sixth day of ‘Chaitra’ (summer) Navratra. The Kapat (door) of famous Yamnotri shrine would be opened this year on May 7 for Char Dham Yatra.
In April-May 2019 India will vote to elect 17th Lok Sabha or Parliament. On April 11, the 1st of the 7 polling days, the home state of Yamuna river, Uttrakhand and the districts of Western Uttar Pradesh through which Yamuna river flows, will vote.
The two other states heavily dependent and Yamuna river, Haryana and Delhi will see voting on May 12. The district Mathura, Agra, Etawa, Kanpur, Hamirpur, Fatehpur and Allahabad of Uttar Pradesh located along Yamuna river will witness voting from second (April 18) to sixth phase on May 12.
The NDA government come to power in May 2014 promising clean Ganga and Yamuna. The thousands of devotees of Mathura and residents of Agra were especially convinced of a promise of clean flowing Yamuna river. People were also hopeful that the government of the same party, BJP, in centre and in key basin states of Yamuna (Uttarakhand, Haryana and Uttar Pradesh) would bring a change in the situation. But over the five years, things have only deteriorated further. In fact, under the present government apart from dams and pollution a illegal sand mining has emerged as equally dangerous threat for the Yamuna rivers from upper reaches through middle and lower stretches.
On the occasion of Yamuna Jayanti, the Yamuna Nadi Mitra Mandli (YNMM) a voluntary group of villagers and concerned; established along the length of Yamuna by Yamuna Jiye Abhiyan is highlighting the issues affecting the Yamuna river and riparian communities which have remained unaddressed during past five years and none of the political parties even now have remotely focused on these. They also warn that ignoring the problems of Yamuna and dependent community will soon affect every state and dependent people in a significant way apart from endangering the river itself.
The release of around 1.31 lakh cusecs of water in Yamuna from Hathnikund barrage at 09:00 hours on July 26, 2018, was certainly first surge of flood this monsoon in the river. But no one expected, most are still in the dark that the release would multiply by over five times in just two days! It is almost a month after the Southwest monsoon arrived. By this time the river usually floods couples of times.
Looking at the lack of significant rainfall in the catchment area over past weeks, the flood is unexpected and has taken many by surprise. The Irrigation and Flood Control Department, Delhi Government has issued warning for flood plain farmers and human settlements close to river banks, but the warning does not seem to commensurate with the flood peak that is likely to hit the capital in next day or two.
Yamuna has already crossed warning (204 m) and danger level (204.83) at Old Delhi Railway Bridge (ORB), Delhi. The High Flood Level is 207.49 meters, reached on Sept 6,1978 after around 7 lakh cusecs (cubic feet per second) water was released in Yamuna on 3rd Sept 1978 at 04:00 hrs from Tajewala barrage, that was decommissioned and replaced by Hathnikund barrage in early 1990s. The flood monitoring of River Yamuna began in 1963.
Since then, the river has seen high floods in 1988, 1995, 2010 and 2013. The 2010 and 2013 floods also crossed 207 metres mark but fell short of 1978 level.
Every year on the sixth day of summer Navratra the birthday of Yamuna river is celebrated. This year it was on 23 March 2018. On this occasion, SANDRP has prepared a photo blog covering almost entire length of the river. The Yamuna Mitra Mandali (YNMM) (Friends of Yamuna River) group established by Yamuna Jiye Abhiyan has essential contributed for this pictorial blog.
The photo blog tries to show the present day situation of river Yamuna and activities of YNMM on the day of Yamuna Jayanti.
Yamuna River is infamous as one of the most polluted rivers of the country. A mere thought of Yamuna, brings the picture of a stinking black water course, in the mind of most of the concerned. But the initial 26 km of the River in Delhi from Palla upto Wazirabad Barrage presents a totally different Yamuna.
Unlike the city part, the river here has clean flowing water. Natural vegetations can be seen standing tall along still inviolate banks. Sighting of riparian birds in good number offers great solace from robotic city life. Few in-know of this secret, go fishing here during leisure and weekends. Farming activities on adjoining lands adds rustic charm to the panorama. If this is not enough, nearby floriculture strips, turns the riverbank colourful.
The river water is bathing quality. Many fresh water birds flock around. Herders take out cattle. Fishermen catch fish. Boatmen ferry visitors on demand. Devotees bath in the river and say prayers. Farmers remain busy with cultivation.
Annual flood marks are visible. It replenishes ground water and enriches the soil. Floodplains are still spared of concretization. All this contributes to make the river live and lovely.

Perhaps we all have our pet projects which we wish would go on forever. I have been working on a Primer on Riverine Fisheries of South Asia for some years now (my office may disagree with the definition of ‘some’). Like a magpie collecting shiny knick-knacks, I keep collecting (quite serendipitously, or so I think) anecdotes and interviews and snippets on the subject.

In addition to the Gangetic Fisheries Primer, SANDRP will shortly publish a Primer documenting the Impacts of dams on Riverine Fish and Fisher Communities. One of the most profound impacts of dams on fish is blocking migration routes and perhaps no other fish symbolizes this impact as dramatically as the Hilsa: the Silver Queen of the River.
Glimpses of the impacts of dams on Hilsa in South Asia.
Arguably, Hilsa is not just a tasty and healthy fish species that migrates from the sea up the river to spawn. It is a cultural icon that binds Bengalis, whether from West Bengal or Bangladesh, together in their shared love for Ilish Machch. Pohela Baishakh or the new year day’s meal is not complete without Ilish. Though Hilsa is celebrated fervently by the Bengalis, it is prized in all estuaries of South Asia, from Narmada, Mahanadi, Godavari, Cauvery to Indus and Irrawaddy and takes the name of Chaski, Palva, Ilishii, Palla, Pulasa, etc. It is also found at confluence of Tigris and Euprates in Iran, where it is as prized and known as Sbour. The fish flavours several poems, folklore, songs and phraseologies of the entire South Asia. In cultural terms, the significance of Hilsa is comparable only to Salmon and Mahseer.
Tenualosa ilisha, Hilsa or Indian Shad belongs to the sub family Alosinae of Family Clupeidae. Commercially, it is the most important fisheries in the estuaries, especially in the Ganga-Hooghly region.It occurs in marine, estuarine and riverine environments and is found in Indus of Pakistan, Irrawaddy of Myanmar and Indian rivers like Ganga, Bhagirathi, Hooghly, Rupanarayan, Brahmaputra, Godavari, Narmada, Cauvery, Tapti, coastal rivers like Padma, Jamuna, Meghana, Karnafuly and others in Bangladesh. It is seen to migrate up smaller estuaries like Pennar too.
Hilsa, by habitat, is a marine fish but migrates in estuaries and rivers for spawning, normally inhabiting the lower region of the estuaries and the foreshore areas of the sea. Hilsa ascends the rivers for spawning and the spent fish and their progeny migrate down the river towards lower estuaries and coastal areas, moving in shoals. The peak upstream migration of Hilsa in most of the rivers of the country is generally in the monsoons months of July and August and continues upto October or November. The spring spawners that enter the river for spawning in January-March return to the sea during July-August when these are caught in good numbers. The monsoon spawners that enter the river during September- October return to the sea after spawning and these spent fishes are caught in good numbers during January- March. Similarly, the off springs of spring-spawners make journey for the sea from the river during November- January, whereas the off springs of monsoon spawners return to the sea from the river during July- September. (Bhaumik et al, CIFRI, 2012)
Obstruction to undertaking this spawning migration by dams and barrages has been singled out as the primary reasons for the fall of Hilsa fisheries in India as well as Bangladesh. The trade of this commercially important fish species constitutes upto 1.5% of Bangaldesh’s National Gross Domestic Product and about 2 million fishers are estimated to depend on Hilsa fisheries in Gangetic estuaries. Till August 2014, Bangladesh has stopped Hilsa exports to India to contain astronomic price rises in Bangladesh as the costs of the fish are becoming uncontainable due to its cultural importance on one hand and dwindling supply on the other. India has requested Bangladesh to lift the ban of Hilsa export, but it is yet to relent, due to a number of socio-political reasons. 
One of the main reasons for the phenomenal fall of Hilsa in Gangetic delta has been the Farakka Barrage built by India in the 1970’s, just a few kilometers upstream the India –Bangladesh border, to divert water from Ganga into the Hooghly river, to keep the Kolkata Port at the mouth of Hooghly, free of sediments.
Prior to commissioning Farakka Barrage in 1975, there are records of the Hilsa migrating from Bay of Bengal right upto Agra, Kanpur and Delhi covering a distance of about 1400 kms. Maximum abundance was observed at Buxar, near Allahabad, at a distance of about 650 kms from river mouth. Post Farraka, Hilsa is unheard of in Yamuna in Delhi and its yield has dropped to zero in Allahabad, from 91 kg/km in 1960s. Studies as old as those conducted in mid-seventies single out Farakka’s disastrous impacts on Hilsa, illustrating a near 100% decline of Hilsa above the barrage post construction.
An obligatory Fish lock provided in Farakka Barrage is non-functional and tagging experiments reveal that Hilsa cannot move across the barrage due to obstruction of three-tire sluice gates. For more on how Farakka has failed its objective and continues to impact livelihoods: https://sandrp.wordpress.com/2014/11/25/lessons-from-farakka-as-we-plan-more-barrages-on-ganga/
Fishers who live off the Ganges strongly feel the pressure of dams, personified by Farakka. In north India, ‘Farakka’ –the word doesn’t mean a village on the Bangladesh border anymore, but means destruction by dams. The local Hindi dialects have borrowed new phraseology: “Farakka hua, tabse hilsa toh bas bhabis” (Farakka happened, and then Hilsa exist only in imagined future)”. The same phrase repeats up to the Yamuna River! In a recent status survey of Gangetic fisheries almost 75-80% of fishers singled out ‘Farakka’ as the root cause of all their miseries. They actually referred to multiple barrages built on the respective rivers. But destruction had a common name: Farakka.
Bangladesh has been making several serious attempts to revive Hilsa fisheries and implements a strict fishing ban in certain months to avoid fishing “jatkas” or small Hilsa. It has also declared several Hilsa Sanctuaries to protect the fish and is witnessing small and steady improvements in the population. India has hardly taken any steps to protect this specie. IUCN has led a program called Ecosystems for Life: A Bangladesh-India Initiative and Hilsa fisheries is a part of this project. There is also a Norwegian project on Hilsa Aquaculture  ( All prior efforts of Hilsa Aquaculture have failed). However, the primary need to address the giant problem of the Farakka Barrage is being unaddressed. The barrage and reduced freshwater in the downstream is also exacerbating other stressors like sedimentation of the river mouth, high fishing pressure on limited stocks, concentrated pollution, etc.
Hilsa in other Rivers (would taste as sweet!) Hilsa is found not only in Ganges delta but most of the estuaries in India. In all of these places, Hilsa fishery is primarily affected by dams and barrages near the estuaries, blocking spawning migration and reducing freshwater from upstream.
Hilsa in Cauvery: A century of impacts In Tamizh, Hilsa caught at Sea is Kadal Ullam and the one in the River is the Aattu Ullam. Here, the impact of Mettur dam on valuable Hilsa fisheries in the Cauvery has been recorded as early as 1939 in an issue of Current Science, where it is stated: “Unfortunately the effect of the dam (Mettur on Cauvery) on the fisheries below was disastrous. The number of valuable Indian Shad or Hilsa, the most important sea fish ascending the Cauvery for breeding purposes, declined as the high floods which enabled them to ascend the rive no longer occur. The serious decline of fisheries in Cauvery would be evident from the fact that the fishery rental of the river below the dam which used to amount to 80000 Rs. annually has steadily declined since the formation of the dam to about 42,900 rupees.”Puntius species also disappeared in Cauvery post dam, which formed 28% of the landings prior to dam construction.
As per the Report “Fishing the Cauvery: How Mettur Changed it all,” by Ramya Swayamprakash published by SANDRP, It was Sir Aruthur Cotton himself, way back in 1867 who alerted the erstwhile government about the damages wrought by weirs on river fisheries. Immediately, Dr. Francis Day was commissioned to investigate the impact on fisheries and subsequently appointed Inspector-General of Fisheries in India. In his report on the fisheries of India and Burma, Day condemned dams as insurmountable barriers to fish passage; he designed a fish passage which was on the Lower Anicut on the Kollidam. The pass was primarily designed for the Hilsa who could not ascend it, as it was too wide. According to the Madras Fisheries department in 1909, the fish pass did not ensure Hilsa migration because of various practical and technical difficulties; in the first place, the expenses for the construction of a fish pass were not commensurate with the expected results and secondly, sufficient water could not be provided for the efficient working of the pass. Interestingly, Hilsa was sought to be cultivated and exported along the lines of the Salmon in north-western United States. So important was the Hilsa that a stuffed specimen made its way into the exhibits sent to the Great Exhibition from the Bombay Presidency, in 1851!
Today, the Hilsa is unknown on the Cauvery. According to fish biologists, the Hilsa ascended the anicuts on the Cauvery up to Mettur to spawn overcoming the low anicuts. But the coming of the Mettur Dam formed an impassable barrier.
Hilsa in Godavari is known as Pulasa when caught i the river and Vilasa when caught n the sea! Here too, the fish is declining and main reasons are said to be declining water levels and the Dowleswaram Barrage  (Arthur Cotton Barrage). In Andhra villages too Pulasa has a huge cultural significance.
This author made a presentation to the Standing Committee of the Lok Sabha, the lower house of Indian Parliament in June 2012 about the impacts of dam on riverine fish and discussed Hilsa, when an MP from Coastal Godavari district in Andhra Pradesh said, “I know Pulasa! My constituency depends on riverine fisheries like Pulasa, and not marine fisheries, but we end up talking only about marine fish and not river fish and Pulasa and the impacts of upstream projects on livelihoods of river fishers”
In Mahanadi, Orissa, Hilsa has been hit by dams and is recording a declining trend. Paradip recorded about 500 tonnes Hilsa, but prices have increased astronomically.
Hilsa in Narmada, Sardar Sarovar and the proposed Bhadbhut Barrage The narrative of damming the Narmada by the Narmada Valley Projects is one of the most significant stories of an on-going struggle against modifying a river and way of life of her people. Although there are many facets to the story ranging from displacement, false benefits and true costs, forest loss, non-existent rehabilitation and an all-pervasive insensitivity of the government towards weaker communities, the impacts of this project on riverine fisheries have been equally profound. Narmada River system experienced a nearly 70% decline in Hilsa catches in just a decade between 1993 to 2004 ( From 15319 t to 4866 t ) and this decline was prominently recorded from 1998-99 onwards. As per CIFRI, the most stressed species after Sardar Sarovar Project (SSP) construction is the Hilsa and Macrobrachium prawn (Jumbo River Prawn). CIFRI made some prediction about impacts of the dam after 35 years, calling it a ‘critical period’ when fisheries will be nearly lost. Shockingly, these conditions are already being witnessed in Narmada Estuary in Bharuch which records nearly 30% Inland Fish production. More than 12,000 people from 21 villages in Bharuch alone depend on Narmada Estuary for fisheries.
Assessment of impact of commissioning of Sardar Sarovar dam and other projects in 2009 by CIFRI revealed that SSP will retain 96% of the sediment, adversely affecting biological productivity of the downstream including Narmada estuary. However, already the Sardar Sarovar and upstream dams in Narmada Basin have already resulted in retention of about 95% sediment, cutting off the delta from nutrient rich silt. Historical sediment discharge of Narmada was 61 million tonnes and the current sediment discharge (average of last ten years of the study) was found to be 3.23 million tonnes.
According to CIFRI, “While the annual inflow is 23.68 MAF (1981-1990), it will be reduced to 15.9 MAF after 10th year of SSP, to 4.34 MAF at the 30th year and will cease at the 45th year. This freshwater decline will severely affect Hilsa fishery and prestigious fishery contributed by M rosenbergii (Jumbo River Prawn)”. As freshwater declines, there will be “Steep hike in salinity regime with tidal ingress. Fishery not tuned to such enhanced salinity will succumb to such pressure. Mangroves will also be affected and this will impact marine fish production as Mangroves are nurseries of many marine fish.”
Gujarat Government has agreed to release 600 cusecs water from Sardar Sarovar and Bhadbhut Barrage as environmental flows. There is no study as to whether this amount is sufficient for estuarine balance, for ecological needs of Hilsa or other species, for spawning migration, etc. Also, there is no guarantee that Gujarat will release this meagre quantity. Ironically, the minimum flows of 600 cusecs agreed to be released by Gujarat through SSP come to 532. 9 Million Cubic Metre (MCM) water annually and CIFRI’s warning of a sharp fisheries decline at 30th year was for 4.34 MAF or 5353.4 MCM! So, 532.9 MCM released now as minimum flows is barely 10% of a dire scenario predicted at 30th year of commissioning SSP[i]!
It is hardly a wonder that Hilsa is falling sharply in Narmada Estuary and fishers are directly blaming the Sardar Sarovar for this decline.
Last Straw for Narmada Hilsa: Bhadbhut Barrage: Gujarat Government is planning to build Bhadbhut Barrage about 17 kms from Bharuch, directly affecting the Narmada estuary and the Hilsa and Prawn fishery. The Barrage is planned for SEZ and also water sports and is a part of an infeasible scheme known as the Kalpasar project which plans to dam almost all rivers as they meet the Gulf of Khambat.
The Bhadbhut Barrage is being fiercely opposed by fishers in Bharuch because of its serious impacts on their livelihoods and Hilsa fisheries. Public Hearing of Bhadbhut Barrage was held in July 2013, wherein the fisher community staged a walk out, stressing that the EIA had under-reported Hilsa fisheries in the region, number of fishers and their dependence on the Estuary for fish. The walkout took place immediately after Pravin Tandel, the fisherfolks’ local leader, spoke saying the project would “adversely affect the fish catch, especially Hilsa, once it is implemented. Currently, Hisla fetches Rs 1,200 per kg, and is our main source of livelihood.”
Hilsa in the Indus: In the Indus too, Hilsa fisheries, known as Palla are the main stay of local fisher communities. Hilsa fish is a highly contested territory due to declining catches.
Before the construction of the Sukkur Barrage, the Palla used to reach to Multan as per records of 1907. The Sukkur Barrage and then later the Kotri Barrage severely restricted Palla’s range, affecting the fish and its fishers. According to M. R. Quereshi, ex-Director of Marine Fisheries Department of Pakistan, the Palla used to ascend the river (Indus) to spawn in the middle of June but its ascent is now delayed by at least one month owing to late freshets. Kotri Barrage near Hyderabad has severely restricted its breeding range. Like the Cauvery, in Kotri too the fish ladders do not work due to faulty designs and Hilsa is unable to ascend them, consequently prevented from going up to the upper reaches of the river. As a result the Hilsa fishery is being depleted and immediate action is imperative to increase its production. “Failing this, the fish will eventually disappear from the river.”
To conclude, the fate of this silvery fish hangs in a fine balance. Not only does the Hilsa enjoy huge cultural significance, it also supports millions of livelihoods. In the United States, several dams, like the recent Glines Canyon Dam on the Elwha, have been decommissioned for their impacts on migrating fish and dependent communities. Elwha river dams came down in a biggest decommissioning effort because the indigenous Klallam tribe asserted its rights on traditional Salmon fisheries which were blocked by these dams. In Japan too, Arase Dam was decommissioned because of its impact on Ayu fish and fishers.
What has happened in India to the Hilsa fish and fishers is far more serious.
Hilsa has a striking ecological, economic and cultural significance. Till date, ranching or farming of Hilsa has not worked. Till date, fisher communities continue to face conflicts, hardships and risks, go deeper and deeper in the sea to gather a few Hilsa. Till date, dam operations have not changed, nor have the fish passes been designed, built, operated or monitored to help the fish. Till date, none of the fisher communities who suffered colossal losses when a dam affected Hilsa, have been compensated for their loss.
Is it not time to rethink these dams, to help the fish and our fishers?
