Agara lake is an 80-acre lake located in Agara, Bangalore. It is part of the Varthur lake series. Madiwala Lake is upstream while Bellandur Lake is downstream. Inter-lake connections have seen fragmentation and urbanisation.
Agara Lake is one of the most well maintained lakes of Bangalore.[2] At the inflow end there is a partitioned constructed wetland and a sediment basin with a sluice. The lake is surrounded by a walking and cycling track. There is a park at the north end. An immersion tank has been built here. A storm water drain or rajakaluve flows immediately alongside the lake on its left side. The lake is surrounded by roads on all sides.
Description
[edit]The lake dates back to at least the 8-9th century.[3][4]
The lake is filled by overflowing water from Madivala lake, the surrounding catchment area,[1] and a number of rajakaluves.[3] Surplus water traditionally drained into Bellandur Lake.[3] There is a storm water drain or rajakuluve between Bellandur and Agara lakes. The Agara-Bellandur region or wetlands provides an area for the primary outflow of Agara to flow towards Bellandur Lake via a stream network.[5] This connection has seen fragmentation and urbanization.[3] Land use changes from the 1970s have resulted in a decrease in surrounding water bodies.[3]
From 1990s onwards the surroundings of the lake began to see construction.[3] From traditionally being a community lake for those nearby including Agara village, the lake largely became a recreational public space.[3]
In 2007 the lake was privatised. Following protests against the privatisation, the lease of the lake was cancelled. The private firm then filed a case against the administration.[3] In 2012, the High Court directed a citizen group to manage the lake.[1] A citizen group, the Agara Lake Protection and Management Society, was formed in 2013.[1]
In 2004 restoration work was done on the lake by BDA and the forest department. Citizen initiatives to keep the lake in shape have spanned at least four years.[6] In 2018, with a ₹16 crore (equivalent to ₹33 crore or US$4.0 million in 2023) grant from the state government, the Karnataka Lake Conservation and Development Authority began a de-weeding and desilting program. Surplus silt was used to increase the height of the encircling bunds.[7] The lake has an immersion tank or kalyani that is disconnected from the main lake.[8] The lake is fenced and surrounded by roads on all sides.[3] A park has been created at one end and a walking path encircles the lake.[3]
At the inflow end the lake has a constructed wetland covering 9 acres.[1] Here permeable retention walls create partitioned areas.[1] The partitioned areas allow time for silt to settle and the permeable walls act as filters.[1] Before this system, a manual sluice gate had been installed to control inflow into the lake from a sedimentation area.[1]
In 2018 bird watchers spotted 30 species of birds including Scaly-breasted munia and Red-naped ibis. A decrease in bird numbers was attributed to a number of factors.[9] Fishing rights have been granted to select fisherfolk.[10]
