He Quit His Job to Restore 18 Lakes Across Karnataka

Harsha Tej responded to Bengaluru’s disappearing lakes by taking direct action. He quit his job, picked up a shovel and began restoring water bodies. Through the BlueDot Foundation, his efforts expanded beyond one location and reached lakes across Karnataka. The work matters because lakes support both urban life and natural systems.

Restoration included clearing invasive growth, removing waste and rebuilding habitats. The foundation also planted more than 1.5 lakh native trees. These actions aim to bring back healthier lake environments rather than simply make them look cleaner. They help create space for wildlife and strengthen the landscape’s ability to handle rainwater.

So far, the BlueDot Foundation has helped restore 18 lakes. Harsha’s work shows how sustained, hands-on involvement can produce wider environmental change. Each restored lake can help Bengaluru move toward a future where nature and urban life coexist more closely.

Restoring a lake means helping its wider ecosystem recover. Removing waste and invasive plants is important, but the work also includes rebuilding habitats. This matters because a lake is not merely an empty basin holding water. It is a living environment connected to wildlife, groundwater and the surrounding landscape.

The BlueDot Foundation’s work provides a clear example. Its efforts involved clearing invasive growth, rebuilding habitats and planting more than 1.5 lakh native trees. Native vegetation can support local wildlife and strengthen the area around the lake. A healthier landscape can also manage rainwater more effectively.

This broader approach makes restoration different from cosmetic cleaning. The article presents each restored lake as part of a larger environmental recovery. Across Karnataka, 18 lakes have been helped so far. The aim is to bring back water bodies that support both nature and urban life.

The scale of the BlueDot Foundation’s work is measured in both water bodies and trees. It has helped restore 18 lakes across Karnataka and plant more than 1.5 lakh native trees. These figures reveal a coordinated environmental effort rather than a single, isolated cleanup project.

The restoration work included clearing invasive growth and rebuilding habitats. Tree planting added another layer by bringing native vegetation back into the landscape. Together, these actions can support wildlife, improve the surroundings and help lakes manage rainwater. The work therefore addresses the lake and its connected habitat.

The numbers also show why local action can have wider significance. Bengaluru’s lakes are under pressure from concrete and waste, yet restoration is happening across the state. Each of the 18 lakes represents progress toward healthier water bodies. The more than 1.5 lakh trees add lasting ecological support to that effort.

Bengaluru’s flood-and-shortage paradox reflects two different problems with the same landscape. During monsoons, intense rain can overwhelm urban areas, especially when natural water bodies and open ground have been replaced by concrete. At other times, the city lacks enough stored or replenished water to meet demand.

The article connects this tension to lakes disappearing beneath concrete and waste. Healthy lakes can receive rainwater and help recharge groundwater. When lakes are damaged or lost, rainwater may run off quickly instead of soaking into the ground. That can contribute to flooding during storms while leaving less water available later.

The article does not provide detailed measurements of Bengaluru’s drainage or water supply. Still, it presents lake restoration as one response to both pressures. Restored lakes can improve rainwater management and support groundwater recharge. Protecting them could help the city become more water-secure over time.

Healthy lakes function as living parts of the urban landscape. They can support wildlife, help recharge groundwater and improve the area’s ability to manage rainwater. These benefits matter because cities need places where rain can collect, spread and interact with the natural environment instead of rushing across hard surfaces.

The article links lake restoration with clearing invasive growth and rebuilding habitats. It also describes the planting of more than 1.5 lakh native trees. Recovered habitats give wildlife better places to live, while open lake areas and surrounding vegetation can slow rainwater and allow more of it to move into the ground.

This does not mean restored lakes alone can solve every flood or shortage. However, the BlueDot Foundation’s work shows how natural infrastructure can complement urban systems. With 18 lakes helped across Karnataka, restoration offers Bengaluru a way to manage rainwater while strengthening ecosystems and groundwater supplies.

Restoring a lake works with natural systems instead of relying only on engineered structures. A concrete drain mainly moves water away, and a storage tank mainly holds water in a designed container. A healthy lake can do both storage and wider ecological work. It can support wildlife, recharge groundwater and improve rainwater management.

The BlueDot Foundation’s approach included clearing invasive growth, rebuilding habitats and planting native trees. These steps restore the lake’s surrounding ecosystem, not merely its capacity to contain water. The result can be a more connected landscape, where water, soil, plants and wildlife interact.

Drains and tanks can still be useful parts of city infrastructure. However, they do not automatically provide the same habitat or groundwater benefits as a healthy lake. The article’s example of 18 restored lakes suggests a broader model for Bengaluru: protect natural water bodies while using built systems where needed.

When rain falls on open ground, some water moves into the soil through small spaces between soil particles. It travels downward and can collect in underground layers, becoming groundwater. Lakes and surrounding natural areas can help this process by holding rainwater long enough for more of it to soak in.

Urban construction interferes when concrete, roads and other hard surfaces cover soil. Water cannot easily pass through these surfaces, so it runs across them and may collect quickly in low areas. If lakes are also filled with concrete or waste, there are fewer natural places to store rain and support groundwater recharge.

The article does not explain this process in technical detail, but it identifies the relevant problem: lakes disappearing beneath concrete and waste. Restoring lakes can help recover some natural water-management capacity. It may also make Bengaluru better prepared for heavy rain and future water shortages.
