Lalbagh Lake restored using science-led nature-first methods, boosting dissolved oxygen, reducing nutrients, controlling algae, enhancing biodiversity, and improving overall ecological balance spread across 30 acres in Bengaluru's Lalbagh Botanical Garden. Lalbagh Lake had fallen into severe ecological distress, showing foul odour, pale-yellow water, eutrophication, and dangerously low dissolved oxygen levels. In December 2024, a long-term ecological restoration project was launched, not as a beautification effort but as a science-driven recovery mission. Combining nature-first approaches with biological and mechanical treatment systems, the initiative tackled core ecological failures, achieving a sustainable revival of the historic waterbody.
