Sir,

Hebbal Lake, located in Hebbal industrial area, is facing a severe ecological crisis. Over 60% of its surface is now covered by floating plants, primarily water lettuce. This invasive plant forms dense mats on the water’s surface, blocking sunlight, depleting oxygen levels, and harming aquatic life. If left uncontrolled, water lettuce can completely alter the lake’s natural balance, leading to severe ecological damage.

The unchecked spread of these plants is reducing oxygen levels, making survival difficult for fish, birds and other aquatic species. If the situation worsens, the lake could soon experience eutrophication — a process where excessive plant growth depletes oxygen, killing aquatic life and turning the lake into a stagnant, lifeless water body.

Authorities must take immediate action to prevent further degradation through mechanical removal of floating plants, water aeration and scientific assessment of nutrient levels. Community involvement is also essential — residents can help raise awareness and participate in clean-up efforts.

Hebbal Lake is an essential natural resource that sustains local wildlife and ecosystems. Without timely intervention, its delicate balance could be permanently disrupted. A collective effort is needed to restore and protect this vital water body before it’s too late.
