A viral social media video media shows the frightened impact of a huge scale blasting work done for building the main structure of controversial Lakhawar dam on Yamuna river in Dehradun district, Uttarakhand. As per the locals, the blast took place in the morning hours of April 07, 2025, and caused shaking of hills to a large extent apart from blocking the flowing course of river with enormous debris for several hours forcing the project authority to employ heavy machines to clear the blockage.

The social media post shared with the video mentioned that the heavy blast scared the birds in the area and questioned how the company was allowed to destroy the entire hill environment. The heavy blast has indeed created havoc for the aquatic life in the river and downstream projects.

Post July 2023 unusual flood spell in Yamuna river reaching unprecedented levels in Delhi, the Ministry of Jal Shakti (MoJS) on August 06, 2023, constituted a committee for conducting a “Joint flood management study of river Yamuna for its reach between Hathnikund and Okhla Barrage”. The Committee headed by Chairman, Central Water Commission (CWC) & Ex-Officio Secretary to Govt of India with members from Haryana, Uttar Pradesh, NCT of Delhi and expert Organizations was mandated to examine the meteorological aspects, return period of floods, discharging capacity of barrages, functional requirement of ITO barrage, etc.

The findings of the latest Project Dolphin Survey Report released on March 3, 2025, by Prime Minister Narendra Modi in presence of Union Environment Minister Bhupendra Yadav have raised significant concerns over proposed Pachnad Major Irrigation Project.

While the survey reiterates the adverse impacts of dams, barrages fragmenting the national aquatic animal’s habitat as the population has been found nearly absent between Narora barrage and Kanpur barrage stretch in main stem of Ganga, it also reveals that the endangered species are preferring refuge in Ganga tributaries and confluence points and has been found in highest numbers along 47 km long river stretch between Chambal and Pachnad in Bhind which still undammed.

दिल्ली में नई सरकार: क्या अब निर्मल होगी यमुना?

February 16, 2025 SANDRPLeave a comment

दिल्ली विधानसभा चुनाव प्रचार के दौरान यमुना नदी प्रदूषण एक महत्वपूर्ण राजनितिक मुद्दा बना। चुनाव जीतने के बाद स्वयं प्रधानमंत्री और भाजपा पार्टी के वरिष्ठ नेताओं ने ‘आप’ सरकार की हार के लिए यमुना की दुर्दशा को एक प्रमुख कारण बताया। साथ में यमुना को साफ करने की बात कही। ऐसे में क्या दिल्ली के नागरिक एक स्वच्छ बहती नदी की उम्मीद रख सकते हैं?

Yamuna Manthan 050225: River Needs Attention beyond Politics & Elections

Political blame games surrounding the Delhi assembly election have brought Yamuna in focus for about past one month. Disappointingly, the central and all state govts in basin are responsible for continual degradation of river and none of the parties have offered practical solutions to improve the condition of the river in the national capital.

It’s a fact that the pollution from Haryana drains, namely Dhanaura Escape in Karnal, Drain No 2 in Panipat and Drain No. 6 and 8 in Sonipat have been bringing untreated effluents in increasing amounts in the river upstream of Delhi, ultimately severely crippling the Wazirabad barrage based potable water supply in the city. In addition to diversion of river waters for industrial, irrigational and potable demands from Hathni Kund Barrage, increasing unsustainable mechanized mining for about past eight years have been ruining lean season flows in the river in upper segment. The concerned central govt departments and Haryana government are required to address these issues effectively as part of a solution to improve the health of river in Delhi.

DRP 200125: Whither Env Clearance Rejection rate from Expert Appraisal Committee or MoEF?

January 20, 2025February 28, 2026 SANDRPLeave a comment

A detailed review of functioning of Union Ministry of Environment and Forests’ (MoEF) Expert Appraisal Committee (EAC) on River Valley Projects (RVP) for 2024 by SANDRP shows that the committee or for that matter MoEF has almost non-existent rejection rate. Even when a project is not cleared, when it applies again, it gets clearance, whether the application if for stage I (Terms of Reference) or Stage II (Environment Clearance- EC) clearance. Even in some cases like Pump Storage Projects (PSP) in Western Ghats or the Hydropower projects in disaster prone Himalayas, including the disaster-stricken projects like the 1200 MW Teesta III projects in Sikkim, the scrutiny including field visits by the EAC Sub committees is minimal, not worthy calling even scrutiny.

Having covered dam induced flood incidents and embankment breach flooding events in part 1 and part 2, this third part on annual overview compiles media reports on manmade Urban flood disasters in India during the year 2024. While the cities of Pune, Nasik, Nagpur, Vadodara and Bharuch were affected by dam induced floods, the high discharges from Prakasam barrage and multiple breaches in Budameru river deluged the Vijayawada city. Interestingly, these urban flood episodes coincided with heavy rainfall events giving a reality check to dam and city managers.

In addition to failure in dam management, the deluge in Pune, Vadodara and Vijayawada city were particularly worsened by river front development projects and encroachment on river floodplains putting question marks on the urban planning and development works in these cities. Similarly, the breach in embankment of Munak canal in Delhi flooded several homes Bawana area during the monsoon season.

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.
