Thazhambur, a locality nestled between Sholinganallur and Navallur in the southern region of Chennai has experienced extensive growth in recent years. This is mainly due to its proximity to the IT corridor of Old Mahabalipuram Road (OMR), which is 8.7 kms away. This has led to rapid urbanization in the area with a thriving residential community.
Explore the compelling tale of the EFI restored Thalambur Pond:
Chakkili Lake in Thazhambur
The Chakkili Lake is located in Thazhambur and spans across 10.5 acres.
In its natural state, the lake area looks like a forest with an impressive array of native trees along with weeds that have rampantly grown over time. The ecological significance of the lake, along with the need to preserve its natural beauty, led to the decision to restore to its former glory.
Zones of Chakkili Lake
Chakkili Lake showcases distinct zones, each brimming with rich biodiversity. The shallow littoral zone is filled with plant life, hosting a variety of terrestrial plants and native vegetation. This area is further enriched by a bund and plantation beds, creating a thriving environment for local flora and fauna.
The ponds in the limnetic zone is home to plankton and other aquatic organisms and attract a wide range of birds, including egrets and peacocks. This diverse habitat supports a healthy balance between terrestrial and aquatic life, making Chakkili Lake a blue-green wetland ecosystem.
E.F.I took on the crucial task of reviving Chakkili Lake, ensuring the preservation of native species and addressing the challenges posed by invasive plant species and environmental degradation.
The Restoration Process: A Sustainable Approach
Deweeding
The first significant step in the restoration was deweeding the lake, which had become overrun with invasive plants. A total of 8 acres have been deweeded, giving native flora and fauna the space they need to flourish.
Recharge Pits
Two recharge pits have been created, further enhancing the lake’s ability to manage water. These pits help in capturing rainwater, improving groundwater recharge and supporting the groundwater table. This step is vital for sustaining the lake’s ecosystem during dry spells.
Bund Construction
One of the key aspects of the restoration process is the construction of a bund, which will provide a proper structure and prevent erosion. Currently, a 25-meter stretch of the bund is under construction.
Trench Work
Trenches are being dug to facilitate proper water flow and recharge the groundwater levels in the surrounding area.
Future Plans to Ensure Long-Term Sustainability
While the work at Chakkili Lake is already underway, several crucial steps remain to ensure the lake’s long-term sustainability.
Desilting: The lake area will be desilted to help restore the natural depth and flow of the lake, improving its capacity to hold water and supporting aquatic life.
Fencing: Fencing will be installed to protect the lake area from encroachments and human interference. It will help in preserving the natural habitat for wildlife and ensure that the restoration efforts are not compromised.
Plantation: A plantation drive will be conducted around the lake, planting more native trees to enhance biodiversity. The native trees will help restore the ecological balance in the neighbourhood.
