Fears Of Subsidence In Nainital, Unlikely 'Villains' Are Causing Cracks On Naini Lake's Edge
Cracks in Nainital Lake's retaining walls have raised alarm, with experts blaming rat burrows and fish activity for weakening the structure and threatening its stability
Naini Lake, the iconic feature of Nainital, the world-renowned lake city in Uttarakhand, is facing a new and unusual challenge. The retaining walls along its banks are weakening, with cracks appearing in multiple locations.
This alarming development could pose a serious threat to the lake's future existence. Surprisingly, the culprits behind this damage are rats burrowing along the lake's edge and certain fish species living in the water.
Sections of the wall stretching from Boat House Club, Pant Park, and Band Stand to Capital Cinema in the Mallital area have become particularly vulnerable. Visible cracks and signs of ground subsidence are raising concerns among locals and authorities.
According to local boat operators and shopkeepers, the situation has worsened due to rats digging burrows into the lake's retaining walls. Narendra Singh Chauhan, Secretary of the Nainital Boat Owners Committee, stated that the number of rats has grown rapidly, especially near Pant Park, Boat Stand, and the lake's edge.
He believes sweet corn sold around the lake could be attracting them. Tourists frequently consume corn and discard leftovers nearby, providing rats with easy access to food and encouraging their growth. These rodents are now hollowing out the walls by digging into them, compromising their structural strength.
It's not just the rats; fish in the lake are also adding to the damage. Dr Ashutosh Mishra from the Department of Fisheries at Pantnagar University explained that the Common Carp, a fish species found in Naini Lake, digs through soil in search of food. This activity not only disturbs the lake bed but may also weaken the base of the shoreline walls. According to him, this could be contributing to ground subsidence and erosion.
The Irrigation Department and the local municipality have taken note of the issue. Assistant Engineer D.D. Sati of the Irrigation Department said that repairs have already been made in the Pant Park area of Mallital, and work is underway on other damaged sections.
He confirmed that rat burrows have indeed caused damage and said the issue is being taken seriously. A permanent solution will soon be devised in coordination with the municipality to address both the rats and the structural concerns.

Plans afoot to resume SLBC tunnel work soon as Irrigation Dept. ropes in experts from Army
HYDERABAD The Irrigation Department is planning to resume work at the earliest on the Srisailam Left Bank Canal (SLBC) tunnel, which was halted on February 22 following collapse of the tunnel roof, about 14 km inside from the mouth, near Domalapenta, in Nagarkurnool district, burying 8 workers alive. Another 10 km tunnel is to be excavated to meet the work done from the other side. This was decided at a meeting held here on Saturday by Minister for Irrigation and Civil Supplies N. Uttam Kumar Reddy for an in-depth review of the pending work. The 43.931 km tunnel work was taken up from two sides – from Srisailam reservoir side near Domalapenta, and from Dindi balancing reservoir on the other side. The work was stopped in 2023 following a problem in the tunnel boring machine (TBM) from Dindi reservoir side. It was stopped in the Domalapenta side much earlier, again due to some problems in the TBM. It was resumed on February 22 after replacing some parts of the TBM in the Domalapent end, but within four days, the roof collapse incident took place. Only two of the 8 bodies were recovered before the rescue operation was abandoned in April-end, following the advice of the experts over the danger in taking up debris removal in the last 50 meters of the tunnel excavated from Domalapenta side. The Minister stated that drilling and blasting (excavation) was to be taken up in an estimated 10 km length for completing the tunnel. Terming SLBC lifeline for Southern parts of Telangana, he said its completion must be treated as a top priority and executed with urgency. He explained that the SLBC tunnel would be taken up/resumed using the latest electromagnetic survey technology in collaboration with the National Geophysical Research Institute (NGRI) and the Geological Survey of India (GSI). To ensure precise planning and seamless execution, he instructed the officials to expedite the (aerial) LiDAR survey. Earlier in the day, he had a meeting with a team of NGRI scientists to finalise the technical modalities of the survey. He reiterated that cost would not be a constraint, but highest quality and speed must be maintained at every level. The meeting also marked the first formal interaction with Col. Parikshit Mehra, an acclaimed tunnel engineering expert who recently joined the Irrigation Department on deputation. The Minister expressed confidence that Col. Mehra's expertise would help resolve long-pending technical challenges and fast-track completion of the SLBC and other key tunnel projects. He stated that Gen. Harpal Singh, former Engineer-in-Chief of the Indian Army, too would be appointed as an honorary Advisor in the Irrigation Department soon to strengthen the department's technical capacity and tunnel execution capabilities. The Minister also reviewed the progress of de-siltation and de-sedimentation works across the Krishna and Godavari basins, which he said were essential to enhance/restore the storage capacity and improve water management. He pointed out that water storage capacity of several irrigation projects had come down drastically due to sedimentation and silt accumulation.

District-Level Training Held for Water Resources Census: Emphasis on Accurate, Paperless Data Collection
Gadwal: Chief Planning Officer Yoganand emphasized that precise and unbiased data collection is essential for effective government policy-making. He instructed officials to ensure that every detail is recorded comprehensively and impartially. Speaking at the district-level training program held on Saturday at the IDOC Video Conference Hall, Yoganand addressed officials as part of the 7th Minor Water Resources Census and the 2nd Water Bodies Census for the agricultural year 2023–2024. He highlighted the importance of these censuses, stating that collecting detailed information on groundwater sources, surface water bodies, ponds, tanks, check dams, dug wells, and other minor irrigation sources in villages would provide a holistic perspective on rural water security. The 2023–24 census stands out for a significant advancement—for the first time, data will be recorded through a 'Mobile App'-based, paperless system, using LGD (Local Government Directory) codes for every village. Yoganand further informed that the census of dug wells will be conducted with the assistance of the Groundwater Department, while the enumeration of medium and major irrigation sources will be carried out under the supervision of the Irrigation Department. Detailed training was provided on schedule filling procedures, technical guidelines, data accuracy, and timely reporting to ensure a smooth enumeration process. Officials from the District Irrigation Department and Groundwater Department attended the program and shared key instructions and suggestions. They emphasized that the training sessions were designed to give clear understanding and guidance to all participants involved in the census. The Chief Planning Officer and associated officials called on all staff to ensure that the data collected meets the quality and accuracy expected by the government. Participants of the training included planning and statistical officers from all mandals, sub-statistical officers, and other relevant field functionaries. This initiative is expected to play a pivotal role in understanding local water resources and contribute meaningfully to water security and sustainable irrigation planning across rural Telangana.
