Varthur lake – sluice gate project

Varthur lake – froth and debris

Varthur lake sluice gate project gets a new deadline.  According to the BDA the work will be completed by April 2019.

The sluice gate project has already missed many deadlines.  

History – Varthur lake

Varthur Lake is an artificial lake, or tank, located in the Bangalore South taluk of the Bangalore District in Karnataka. This lake has played an important role in maintaining water resources for irrigation since its construction during the Ganga Empire over 1,000 years ago (Karnataka State Gazetteer, 1990).

Over the centuries, the lake has developed into a complex ecosystem that provides habitat for a variety of plant and animal species.  This includes resident and migratory waterfowl.  The lake also provides the local community with a pleasant micro-climate and considerable pleasing appeal.

Inter-connection and degradation

Varthur lake is part of a system of interconnected tanks and canals that receive practically all the surface run off, waste water and sewage from Bengaluru South.  Urbanization and population expansion in Bengaluru and surrounding towns and villages have taken a brunt on many tanks.  Varthur lake is one among them.

Pollution has exceeded the ability to integrate contaminants.  This has lead to visible degradation of the quality of water in the lake. 

Sluice gate project – Varthur lake

The BDA has completed the installation of sluice gates in the varthur lake and are working. The 20 metres of the waste weir is yet to be completed.  BDA has set April as a deadline for the work completion.

According to the residents the contractor has not received enough funds from the authority to carryout the work, hence the delay.  The work was halted due to the construction of the new bridge adjacent to the old bridge in varthur.  This demanded diversion of water.

Present scenario

Lake bed is still filled with excess soil and debris. The minor irrigation department had dug it up to set up KC valley pipelines.  The clearance of the debris is yet to take place and restore the lake-bed.
