Bangalore, known as “The City of Lakes” in earlier days was established with several tanks and lakes to impound runoff water for better utilization and enhance the beauty of our Garden City, by Kempegowda, the founder of Bangalore,

There were around 262 water bodies in Bangalore, of which only 34  are recognized as live lakes, which shows a decrease in terms of water spread area.  Way-back in 1883, contamination in Ulsoor Lake was found, from which time the lake water for public consumption was prohibited.

Role of Lakes

In the urban area of Bangalore, water bodies cover about 5% of the land. The lakes of Bangalore have attained an important ecological status as the lakes have turned into lentic-closed aquatic habitats. These lakes form a unique irreplaceable system and are home to a diversity of living beings.
A large number of lakes in and around Bangalore had a vital hydrological role in recharging groundwater in its lower command areas and in the valley portions enriching the flora and fauna and giving a green belt around every lake. The terrain of Bangalore is such that the water flows out on sloping land, but does not infiltrate quickly into the surface soil horizon. If this runoff water is not trapped and groundwater aquifers not recharged, the scenario would indeed become bleak.

Lakes are vital parts of freshwater ecosystems of any country. A freshwater lake when maintained free from pollution can offer many beneficial uses in an urban area.

BlueGreen Water Technologies’ solution was distributed into Chippewa Lake to kill the cyanobacteria in the algae bloom without harming the environment.  BlueGreen is a privately held company based in Tel Aviv, Israel, dedicated to developing novel solutions to water-related problems.  The products of BlueGreen Water Technologies are market approved and hard tested in multiple markets, including in Israel, the United States, China and South Africa.

The Lake Guard™ Blue and Lake Guard™ Oxy, are floating, slow-releasing formulations of market-approved algaecides designed to prevent the intensification of cyanobacterial toxic blooms in freshwater bodies (aka “blue green algae”).  Both certified internationally to meet the NSF/ANSI-60 standard for drinking water.

Lake Guard was designed to fuse market-approved, well-validated algaecides with a novel delivery mechanism thereby removing all pre-existing limitations in terms of feasibility, affordability and eco-friendliness,” according to the company.


“It’s a good way to protect the fish, protect all the beneficial algae, and all the plants that are in the lake, so we are very optimistic,” said Mark Krosse, a volunteer with the Save the Lake Coalition in Ohio.


According to the US-based Environmental Working Group, “In recent years, algae blooms – actually microscopic bacteria called cyanobacteria – have erupted in hundreds of lakes nationwide, putting at risk Americans whose drinking water comes from those lakes, or who swim, ski or fish in them.”


The years of efforts and tons of hard work by activists and civic bodies to rejuvenate lakes in the city have gone futile, due to many on the verge of losing their ecosystems despite getting a revival boost.
