Arekere Lake is situated in the Arekere - Hulimavu area of the city of Bangalore. Originally spread over an area of approximately 37 acres, the lake is bounded on the west by Bannerghatta Road, on the north by BDA Eighty Feet Road, on the east by Shantinikethan Layout and on the south by Hulimavu Main Road. According to the BBMP website, the perimeter of the lake is about three kilometers. It was possibly a manmade water reservoir created approximately 100 years ago.
The lake is under the jurisdiction of the Bangalore Development Authority (BDA). As is the case with many other lakes in Bangalore, in the last two decades the Arekere Lake has been encroached upon by real estate developers, and the current extent of the lake has been estimated to be only approximately 25 acres. Also due to rapid urbanization of the rain catchment area of the lake and the consequent lack of seasonal water filling, by the end of the first decade of the 21st century the lake had nearly dried up. In October 2012 the lake was breached, and sewage water flowing out of the lake flooded the nearby residential areas. Following the floods, BDA prepared a detailed plan for the development of the lake at a cost of Rs.14 crore.

Concerned over the deteriorating quality of the lake, several residents in the area formed a collective called the Arekere Neighbourhood Improvement Trust (ANIT) with the express purpose of coordinating all efforts to rejuvenate the lake. The Trust was registered on 30 June 2012. The formation of the Trust was inspired by the success story of Puttenahalli Neighbourhood Lake Improvement Trust (PNLIT) formed in June 2010. The Trust has succeeded in creating awareness of the need for citizens' initiatives for saving the dying Arekere Lake. This was achieved by organizing several programs, including the formation of a human chain along the boundary of the lake.
In early 2015, BDA began work related to the development of Arekere Lake, along with 16 other lakes in Bangalore. The planned activities include de-silting, weeding, fencing, setting up counter bunds, inlets and outlets, construction of paths for walking around the lakes, and seats for walkers.
Environmental protection groups Save Bangalore Lakes Trust and Namma Bengaluru Foundation together published a report on the encroachment of lakes in the city. The report contains information on the total area, encroachment details, BBMP action plan, and survey numbers of 43 lakes in Bangalore. It also contains several maps and satellite images. The report also contains a detailed status report with several images prepared by Dr. Arbind Kumar Gupta, a trustee of Arekere Neighbourhood Improvement Trust.Survey on Lake Encroachments (PDF).
