Rescuing Kaarakuttai A Forgotten Lake’s Revival With Drone Technology

Once a thriving water body, Kaarakuttai — a small yet vital lake in northern Coimbatore — had been reduced to a shadow of its former self. Shrubs had claimed the shoreline, debris piled up along its banks, and its water-holding capacity had dwindled.

But when Siruthuli, a renowned NGO dedicated to water conservation, joined hands with SKYX Aerospace, the vision was clear — to breathe new life into Kaarakuttai using cutting-edge drone technology.

This wasn’t just about mapping a lake – it was about uncovering hidden vulnerabilities, redefining its potential, and ensuring it could hold its ground for years to come.

Mission

Mapping the Forgotten Waters

Our mission began with a detailed Drone Mapping Survey to capture every corner of the lake. But this wasn’t an ordinary mapping exercise — our objective was to unlock crucial insights that traditional methods often overlook.

Armed with precision drones and advanced GIS technology, our team launched a mission with multiple objectives:

  • Total Area Mapping: Surveyed the lake’s entire perimeter to establish accurate boundaries, identifying encroachments, structures, and vegetation.
  • Elevation Analysis: Scanned both the lake bed and its surrounding landscape to detect subtle elevation changes.
  • Digital Twin Creation: Built a stunningly detailed 3D replica of Kaarakuttai to serve as a reference for future
    conservation work.
  • Water Holding Capacity Analysis: Calculated the lake’s maximum capacity down to the last liter.
  • Surplus Weir Identification: Simulated rainfall and water inflow patterns to identify the lake’s spillover point.
  • Water Flow Simulation: Predicted the lake’s natural water-filling behavior to spot potential weak points.
  • Bund Weak Point Identification: Used elevation data to flag vulnerable points in the bund that could lead to structural failure and flooding.
From Data to Action: Turning Insights into Impact

Once our mapping was complete, the results revealed that the lake’s original capacity had been drastically reduced. Shrubs, silt deposits, and unwanted structures were choking its potential.

The data we provided enabled Siruthuli and its partners to take targeted action:

  • Dense shrubs were cleared.

  • Unwanted structures were dismantled.

  • Parts of the lakebed were carefully excavated to increase its capacity.

Every decision – from where to dig to which areas required reinforcement – was driven by data from our drone survey.

Transformation Unveiled

The Final Step: Showcasing the Transformation

Once the rejuvenation was complete, we deployed our drones once again to perform a Post-Rejuvenation Mapping Survey.

The results were breathtaking.

Our second mapping not only showcased the increased storage capacity but also visually captured the dramatic transformation of Kaarakuttai. By overlaying Before vs. After data, stakeholders could see:

  • Areas that had been deepened to boost capacity.
  • How the water flow path had improved.
  • Weak points in the bund that had been successfully reinforced.
The Impact: Data-Driven Conservation Done Right
  • Faster Project Execution: What would have taken weeks to survey manually was accomplished in just one day with our drones.
  • Enhanced Water Holding Capacity: Strategic excavation increased the lake’s storage potential — ensuring more water for local communities.
  • Improved Flood Prevention: Early detection of weak bund points allowed timely reinforcement, protecting nearby areas from potential flooding.
  • Smarter Conservation Strategies: The precise Before vs. After comparison provided a powerful tool for stakeholders to showcase the project’s success to the public.
A Forgotten Lake, Now a Lifeline

Thanks to Siruthuli’s dedication and SKYX Aerospace’s technological expertise, Kaarakuttai is no longer a neglected water body — it’s now a thriving ecosystem with renewed potential.At SKYX Aerospace, we believe that data can drive transformation — and this project proved just that.
