Madiwala lake is one of the biggest lakes in Bangalore, spread over an area of 114.3 hectare situated in the BTM Layout in Bangalore, Karnataka. It is a home to many migratory birds. There is also a beautiful Children park.
As the city's growth spiraled, the Madivala Lake was subjected to intense pollution, with the blockage of inflow channels, encroachments into the catchment area and inflow of sewage water. All these had transformed the lake into a very large sewage pool. Madivala Lake, which was once, a fresh water tank, was fully covered with thick growth water hyacinth, thus preventing aeration and affecting the bio-diversity of flora and fauna. The restoration process was started in Aug 2008 to clean up the lake and restore it to its original beauty. Now the water in the lake is crystal clear. The area of Lake Restoration encompasses 108 hectares, for desilting, island formation, bund formation, wetland and recreational area, forming an important landmark in the city of Bangalore.
The forest department has started boating services as well, by Jan 2009. There are six pedal boats in the lake. Rs 20 is charged for a two-seater boat ride and Rs 40 for a four-seater ride.
Madiwala Lake hosted the second Kere Habba of 2016 on 23rd Jan. The first Kere Habba was held earlier in January at Kaikondrahalli Lake. The activities included Bird Watching, Yoga by the Lake, Cycling, Clay Modeling, Drawing/Sketching, Tree naming/Treasure Hunt, Talk by the LDA and Street Play.
