It is well known that excessive diversion of Yamuna waters at the Hathnikund Barrage (HKB) in Yamuna Nagar, Haryana over the past two-and-a-half decades has turned the perennial river into a seasonal stream in its upper reaches during the lean season. However, an analysis of the Central Water Commission’s (CWC) hourly discharge figures and hydrographs since July 1, 2026 reveals that the river is now being deprived of its essential flows even during the monsoon.

In a significant development, the ongoing proceedings before the Hon’ble Supreme Court on May 27, 2026, in the Kondli drain pollution matter appear to have expanded into a broader Yamuna rejuvenation case. Notably, this marks the third such intervention by the apex court, with the previous two not resulting in any substantial change in river governance or pollution control or state of the river.

Fresh protests over the past month by tribal communities affected by the Ken-Betwa River Linking Project have again raised serious concerns about its environmental impact and social costs. The project is going ahead despite questions over its hydrological assessment and environmental, forest and wildlife clearances.

केवल सफाई नहीं, चाहिए समग्र यमुना नदी तंत्र संरक्षण नीति

October 24, 2025October 24, 2025 SANDRPLeave a comment

दिल्ली चुनाव के दौरान यमुना नदी प्रदूषण एक अहम मुद्दा बना। चुनाव जीतने के बाद नई सरकार निरंतर यमुना सफाई को लेकर कई घोषणाएं और योजनाओं पर बात कर रही है। स्वयं प्रधानमंत्री और उसके बाद केंद्रीय गृहमंत्री, जल संसाधन मंत्री इसके लिए बड़ी बैठक कर चुके हैं। इन सबमें हरियाणा, दिल्ली और उत्तर प्रदेश सरकार द्वारा मिलकर कार्य करने की आवश्यकता सबसे सराहनीय पक्ष रहा है। सरकार द्वारा एसटीपी क्षमता विकास, औद्योगिक प्रदूषण रोकथाम, जल संचयन बढ़ाने और जल स्रोतों को बचाने की बातें भी कही जा रही है। पर ये सब बातें तो पिछली सरकारों द्वारा पहले भी कही जा चुकी हैं और बातों से आगे ठोस नीति और सफल निष्पदान कार्ययोजना की तरफ नहीं बढ़ पा रही है। इन सबके बीच यमुना नदी स्वास्थ्य में गिरावट जारी है।
