Ancient Idols and Modern Waste Unearthed in Bengaluru's Historic Ulsoor Lake Desilting
The deep-desilting of Ulsoor lake, one of Bengaluru's largest and oldest water bodies spanning 108 acres with its distinctive three islands, has brought to light a fascinating mix of historical fragments and contemporary debris. The project, aimed at ecological restoration, has uncovered shards of clay pots, stone sculptures, and mounds of household waste, sparking both curiosity and concern among residents and officials.
Archaeological Inspection Reveals Modern Origins
An inspection by the Department of Archaeology on February 25 determined that most of the 14 sculptures discovered during the desilting process are of modern origin. Experts suggest these idols, including one-foot Navagraha idols, a three-foot Shani idol, a two-foot Bhairava, and marble Dattatreya and Ganesha idols, were likely discarded into the lake during the renovation or reconstruction of nearby temples. According to the Bengaluru Central City Corporation, these artifacts do not hold significant historical value.
However, one notable exception is a Ganesha idol estimated to be around 200 years old, which has been handed over to the archaeology department for its potential antiquity value. This discovery highlights the lake's role as a repository of both natural and cultural sediment over the decades.
Project Aims to Enhance Water Storage and Groundwater Levels
The Rs 24-crore desilting initiative is designed to increase the lake's depth, improve water storage capacity, and raise the groundwater table in the surrounding neighbourhood. Ulsoor lake comprises 15 acres of wetland and the remainder as primary waterbody. It was drained in January, with desilting commencing in February, and currently retains nearly 10% moisture in the lakebed.
Shivajinagar MLA Rizwan Arshad Khan emphasized the necessity of the project, noting that the previous desilting occurred nearly 30 years ago and that bund repairs were overdue. "The desilting is essential to remove decades of sediment accumulation and restore the lake's capacity," Khan stated, adding that beautification efforts are also planned.
Public Reaction and Official Reassurances
The sight of the partially drained lake triggered online reactions, with many residents linking it to Bengaluru's ongoing water concerns. Photographs of the exposed lakebed circulated on social media, with some expressing fears about impacts on groundwater levels and others urging authorities to complete the work before the April rains.
Officials, however, have urged citizens not to panic, stressing that the draining is part of a comprehensive restoration plan. Rajendra Cholan, BCCC commissioner, explained, "Removing the thick silt layer will allow the lake to store fresh rainwater more effectively in the coming seasons." He added that the project is expected to boost groundwater levels in adjacent areas, contributing to long-term ecological health and sustainability.
Beautification and Infrastructure Upgrades
As part of the restoration, the lake will receive a two-level walkway to provide a safe and convenient path for walkers, and its bunds will be strengthened. A bridge linking the lake to a nearby park is under construction, and the neighbouring park will be developed with new plant species to enhance greenery and biodiversity.
Additional features include ornamental grills along the lake boundary to improve safety and visual appeal, and the three islands will be rebuilt to deepen the lake's ecosystem. Officials also noted that the increased water depth could make parts of the lake suitable for training exercises by the National Disaster Response Force.
Logistics and Environmental Impact
The desilting operation involves eight excavators and 40 compactors, with dug-up silt being transported to the Mittaganahalli landfill. The lake is being desilted up to 1.5 metres, targeting both the wetland and primary waterbody. Silt and waste enter the lake through two inlets from the Kalyani and Frazer Town sides, with garbage and sediment flowing in through drains during heavy rains.
Wetland desilting is expected to complete within 15 days, though the primary waterbody may take longer. An official involved in the cleanup noted, "We cannot accurately measure the total volume of silt removed because its moisture content varies."
Items Recovered from the Lake
The desilting process has yielded a diverse array of items, including:
- Fragments of boats
- Navagraha and Ganesh idols
- School bags
- Plastic covers
- Milk packets
- Earthen pots
- Bedsheets, clothes, and glass bottles
This mix of artifacts and waste underscores the lake's historical significance and the challenges of urban conservation. The project represents a critical step toward preserving one of Bengaluru's iconic lakes for future generations.
