While recent rainfall has brought relief to Bengaluru, the preceding dry spell provided an unexpected opportunity for environmentalists to restore two important water bodies in the city.
Bengaluru-based environmental organisation SayTrees undertook restoration work at Krishna Sagara Lake in Yelahanka and Valagere Kallahalli Lake near Sarjapura, taking advantage of lower water levels before the arrival of the monsoon.
Dry conditions aided restoration
According to SayTrees co-founder Deokant Payasi, reduced water levels made it easier to access lake beds and carry out restoration activities.
The dry conditions also facilitated the movement of heavy machinery and allowed uninterrupted earthwork, helping teams complete critical interventions before seasonal rains returned.
At Krishna Sagara Lake, however, the project encountered challenges due to the absence of clearly marked lake boundaries. Concerns raised by local residents prompted authorities to formally demarcate the area.
Engineering and environmental challenges
Co-founder Kapil Sharma said natural groundwater seepage, while a positive sign of ecological health, complicated restoration efforts.
The lake reportedly refilled overnight due to groundwater inflow, requiring repeated dewatering and additional engineering work during bund and revetment construction.
At Valagere Kallahalli Lake, restoration teams had to work carefully because portions of the lake shared boundaries with a graveyard. Rising fuel costs and weather-related disruptions also affected project planning and budgets.
Focus on wildlife protection
The restoration projects were carried out in coordination with the Karnataka Forest Department to ensure wildlife protection throughout the process.
During the work, animals including pond terrapins, snakes and other reptiles were safely rescued and relocated to suitable habitats or handed over to animal welfare organisations.
Environmentalists say the successful restoration efforts will help improve water conservation, biodiversity and ecological resilience in the region ahead of the monsoon season.
