This twelfth edition of monthly Yamuna updates and the first one of the new year 2025, rounds up the critical issues impacting the river eco-system during the past year. The updates of the past one month only hint towards the bleak future the river is heading to. Without addressing the adverse effects and exploring cost effective alternatives, foundation stones of two massive river interlinking projects namely Ken-Betwa and Parbati-Kalisindh-Chambal have been laid. The work of unjustifiable Renuka and Lakhwar dams in climatically sensitive and geologically fragile region of Himalaya is going on.

सर्दी शुरू होते ही दिल्ली में यमुना नदी में झाग की समस्या चरम पर पहुँच जाती है। इसी के साथ कई दिनों तक ओखला बैराज के नीचे नदी सतह पर तैरते ‘आइस बर्ग’ की भांति दिखने वाले झाग के बड़े-बड़े खंड लोगों के आकर्षण और मीडिया की सुर्ख़ियों का केंद्र बन जाते हैं। बढ़ते नदी प्रदुषण पर नागरिकों की बढ़ती चिंताओं और नदी प्रेमियों के बढ़ते सवालों के बीच राजनितिक दोषारोपण का दौर शुरू होता है। समस्या का फौरी निराकरण करते दिखने के प्रयास में संबंधित सरकारी विभाग आनन-फानन में कुछ आधे-अधूरे कदम उठाते हैं। त्यौहार और खास तौर पर छठ पर्व समाप्त होते ही, लोगों की नदी पर जाने वाले भीड़ कम हो जाती है और दो-तीन सप्ताह बाद सब यमुना नदी में बढ़ते प्रदुषण और झाग की समस्या को भूल जाते हैं। लगभग एक साल बाद फिर से यह क्रम दोहराया जाता है जब सर्दी के समय झाग के आगोश में लिपटी प्रदूषित यमुना, नागरिकों की उदासीनता और नदी सफाई योजनाओं की नाकामी को उजागर करती है।

DRP 28×24: Hydropower Impacts on Biodiversity

A new study of available scientific publications on impact of Hydropower projects on biodiversity provides a thorough review of the subject. The review does not directly give a call not to construct more such destructive projects. But it is useful for anyone concerned about the impact of dam projects on rivers.

The study discusses the impacts of hydropower projects on both aquatic and semi-aquatic species in riverine ecosystem and cumulative impacts spatially and temporally across river basins. Dams disrupt longitudinal connectivity and act as physical barriers in upstream-downstream movement of species. Upstream of dam, there is static water environment rather than flowing river environment. In the downstream, the hydropower projects adversely affect the water flow, sediment flow, thermal regimes, affecting water quality and environmental cues for the fish movement. All these also affect the floodplains both upstream and downstream.

The waterbodies, lakes, wetlands in Yamuna basin continue to face damages and threats from many quarters, including concerned govt departments. In latest examples of this, there are reports of Uttar Pradesh govt’s plan to reduce the eco-sensitive zone (ESZ) of Keetham lake to zero. The wetlands also known as Sur Sarovar is a large ox bow lake formed by Yamuna River in Agra. It is a protected bird sanctuary and has been designated a Ramsar site in August 2020. In Sept. 2022, the Supreme Court had directed the govt to increase lake’s ESZ to 799 ha from 403 ha.

Similarly, the Uttar Pradesh govt departments have also been delaying process to notify Dhanauri wetlands as a Ramsar site in Greater Noida. The case is going on in NGT (National Green Tribunal) for the past many years. In the recent hearing held on Sept. 26, the NGT asked govt department to explain reasons behind delay in notifying the wetlands apart from directing it to remove water hyacinth chocking the wetlands. The next hearing will be held on Jan. 27, 2025.

After remarkable deluge in 2023, the upper segment of Yamuna river has seen no significant flood spell all through the just concluded southwest monsoon 2024. This is unusual as the river generally witnesses at least a couple of low or medium flood spells in this segment every year.

However, this year the discharges from Hathnikund Barrage (HKB) in Haryana did not cross 1 lakh cusec figure even a single time. The peak discharge from the barrage was 87,017 cusecs at 06:00 hour on 26.09.2024.

DRP 160924: Urban Flood lessons from Vadodara, Vijaywada

Like every monsoon, a number of cities have faced catastrophic floods in SW monsoon this year. Vadodara and Vijaywada have got the media attention more than any other city for urban floods this year. In both cases a number of factors are common: role of upstream dams, encroachment on water bodies including rivers, lakes, streams, role of illegal sand mining particularly in Vijaywada, not having learnt any lessons from past flood disasters.

It is interesting to see Andhra Pradesh CM hinting at bringing HYDRAA like enforcement institution to remove encroachments on Budameru and other water bodies. Considering the nature of his politics and track record, it is doubtful if this NDA CM will take such a bold step, but it is certainly worthy of consideration for almost all urban areas in India.

The controversial Ken-Betwa Interlinking project is undergoing several changes being proposed by central and state governments of UP and MP. Firstly, there are plans to build two new barrages at Pailani and Banda and renovate Beriyapur and Pariksha weirs and Barua Sagar dam apart from renovation of 15 dams and large ponds in Mahoba district. Then, the construction of a 21 km link channel will require 271 ha of forest land.

Similarly, the CM of MP has requested to increase irrigation capacity of Patne-Biarma Irrigation Scheme from 90,100 ha to 2,50,000 ha under the interlinking plan. On the other hand, the CM of UP has suggested inclusion of Hamirpur district in the plan.

Yamuna Manthan 080824: Welcome Judicial Decisions for River Floodplain

In the past one month there have been some interesting judicial interventions taking up the matters of floodplain, pollution and aquatic eco-system of the Yamuna River in Uttar Pradesh, Delhi, Haryana and Himachal Pradesh. Of these, the most significant one is the NGT order on July 11 fining MoJS & CWC of ₹50 000 each for the non-demarcation of floodplain in Agra.

The fine was to be submitted before Aug. 06,2024 hearing but there is no update available so far on this. It is also not clear whether Yamuna floodplain has been demarcated and officially notified in Agra stretch or not. Earlier in May 2019 and March 2022, the NGT had asked for demarcation of Yamuna floodplain in Agra and Mathura respectively.

The cloudburst induced flashflood destruction took place late on July 25, 2024 in Palchan area of Manali tehsil in Kullu district. Many of the media reports have also mentioned about the deluge damaging a hydroelectric power (HEP) project in Palchan just in a single line without revealing any details or even the name of the HEP.

While looking for more information about the affected HEP, we came to know that not just one but two HEPs have faced significant damages due to the flashflood incident. Both projects are owned and run by private companies in upper Beas River basin.

It has been a year since Delhi witnessed one of the worst flood spells in Yamuna after four and half decade. The unusual deluge in river on July13, 2023 breached the highest flood level (HFL) 207.49 meter at Old Delhi Railway Station (DRS) attained on September 6,1978 by 1.17 m margin and set 208.66 m as new HFL.

Apart from severely impacting thousands of people in the city, the July 2023 Yamuna flood caught the concerned govt agencies responsible for flood mitigation by surprise and exposed the way city planners particularly DDA, NHAI have been dealing with river floodplains.
