Bengaluru’s Historic Lake Gets Rejuvenated – Devanahalli Kere

Located on the Northeastern part of Bengaluru, the Devanahalli town is a historic town well known for the Devanahalli Fort, the birthplace of Tipu Sultan. To the north of this fort lies a water body known as the Devanahalli Lake. This 17-acre large lake plays an important role in providing water for the people residing in the region and several farm lands.

Over the years owing to anthropogenic activities, the Devanahalli Lake was found to be fast diminishing. Excessive dumping of solid waste along its bunds, and no maintenance of the lake leading to uneven bunds with a rampant growth of invasive weeds on its periphery and water surface were rapidly degrading the lake.

With administrative support from the Government of Karnataka, funding support from Kennametal, and philanthropic support from United Way India, E.F.I had taken on the restoration of the Devanahalli Kere.

Removal of Invasive Weeds and Solid Waste

Nearly 768 tonnes of invasive weeds such as Prosopis juliflora and Alligator weeds were from the periphery and surface of the lake. A total of 96 tonnes of solid waste was cleared from the lake as well.

Strengthening of Embankment

The weak embankments of the lake were strengthened using excavators to improve the lake’s resilience in case of flooding, and also enhance the lake’s holding structure.

Nesting Islands

A total of 11 nesting islands were constructed at the lake to serve as a nesting site for local fauna such as birds, reptiles and amphibians to thrive.

Protective Fencing

To prevent further exploitation of the lake, protective outer fencing was installed at the lake. This also provides a definitive boundary to the lake.

The lake with all its new features is now all set to become a biodiversity hotspot of its own!

We thank the local residents and volunteers who helped strengthen our efforts.
