THOUGH THE MADIVALA LAKE STINKS, AND IS INFESTED WITH WEEDS (THAT YOU CAN SEE ABOVE) CHILDREN SWIM IN THIS STINKING LAKE. FORGET CHIKUNGUNYA, DENGUE, DON'T BE SUPRISED TO FIND A MUTATED VIRUS CAUSING SOME NEW "MADIVALA VIRAL DISEASE?!"
THESE KIDS FIND THE LAKE AND THE CANAL STINKING! WHAT ARE WE TEACHING THE NEXT GEN IF WE DO NOT TAKE AFFIRMATIVE ACTION? WHAT WILL WE LEAVE BEHIND FOR THE NEXT GENERATION?!IF YOU CAN INFLUENCE OR PASS THE MESSAGE ON TO NATURALISTS, ENVIRONMENTALISTS OR EVEN THE PRESIDENT OF INDIA, PLEASE DO SO!!

Hi ,
Why you have wasted your efforts and concern towards this cause?
I see you have been inactive since 2006 about this issue.
I started noticing the plight of madivala lake since past one year.Plenty of times have the thought of doing something for this endeared lake crossed my mind.
It has been my friendly neighbourhood's lake for almost last two years.
When I first saw it,I was astonished to discover this beauty among a crowded suburb of bangalore.
Now, I am disheartened to see its plight - the hycenthia weed is increasing like smoke in the air.Each passing day it is choking even larger area of madivala.
This was an article I found in Indian Express which was published in Feb,2001 :
Studies Finally Declare Ulsoor & Madivala Lakes Dead
Heavy metal sludge caused by Ganesha idols' paint choking lakes;
mode of clean up has invited protest from residents, NGO.
--------------------------------------------------------------------------------
Express News Service
Bangalore, Feb 16: Environmental studies conducted by the Central Pollution Control Board (CPCB) southern zonal office here note that pollution levels in Ulsoor and Madivala lakes are so high that they are as good as 'dead'.
Due to high pollution-levels, the lakes are filled with algae, which makes it difficult for any other organism to grow, in a condition known as eutrophication or, simply lake death. The thick layer of sludge at the bottom of these lakes has high levels of toxic heavy metals, the study states.
As the sludge is also contaminated, checking the sources of pollution alone cannot save these lakes. "The entire lake water should be pumped out and sludge should be removed," said a CPCB scientist. Similar clean up is now going on at Hebbal Lake.
CPCB also recommends a ban on immersion of idols in lakes during the Ganesha festival. The algal bloom in the lakes is caused by excess nitrogen and phosphate, which come from the sewage andtraces of garbage and other organic matter that reach the lakes.The heavy metals come from effluents and from paint used in the idols immersed.
CPCB scientists have studied the Sankey Tank as well, and found it is only 'morderately polluted', as it receives only storm water and no effluents. The lake is maintained by the Karnataka State Toursim Development Corporation (KSTDC) which offers boating facilities in the lake.
"Ganeshs festival idols, that are usually immersed in the lake, is the only source of pollution that occurs, that too only once a year," the study notes. The lake bottom sludge traces of heavy metals.
The Madivala lake, maintained by the State Forest Department, receives sewage and storm water from surrounding localities.
The study showed that the level of dissolved oxygen, an important criterion that marks the ecological health of a water source varies in Madivala Lake from a maximum of 18.5 mg per litre (mg/l) to 0.1 mg/l. This variations shows that the lake has got as dirty as it can get.
The science behind the oxygen level variation is that during daytime, tha algae thriving on pollutants release excess oxygen into water, but suck it all up by night, leaving little for other organisms to breathe.
In effect, the water is nowhere fit for fishing. At a dismal 0.1 mg/l it will be lucky to find some fish there.
According to CPCB criteria, dissolved-oxygen level should be at least 4 mg/l to make the water fit for fishing or for water supply after conventional treatment. For outdoor bathing, the level should be at least 5 mg/l.
The sludge at the bottom of Madivala lake contains high concentrations of toxic heavy metals including lead and chromium.
The story of Ulsoor lake is almost the same - a saturation of oxygen level during day but almost nil at night. Precisely speaking 0.2 mg/l. KSTDC and army personnel use the lake and maintain it.
The lake water is cocktail of nutrients including phosphate (3 mg/l) and nitrogen (13 mg.l).
The sludge at the bottom of Ulsoor lake laso contains a rich mix of toxic heavy metals. There is chromium (85 mg/kg), lead (11 mg/kg), cadmium (0.16 mg/kg), zinc (35 mg/kg) and copper (19 mg/kg).
It is learned that such a suggestion from CPCB about the modes of clean up has invited protests from residents and non-governmental organisations.
Nobody wanted to deal with the stinking sludge with traces of toxins. Even temporary storage of sludge in the vicinity of the lake was opposed to sources reveal.
"
BUT WHY IT IS UNDER SUCH AN ABJECT NEGLITION NOW BOTH FROM THE ENVIRONMENTALISTS AND THE GOVERNMENT?
BANGALOREANS,ENVIROMENTALISTS,GOVT: DO YOU KNOW THAT BANGALORE USED TO HAVE MORE THAN 3000 LAKES AT ONE TIME .NOW THIS NUMBER HAS SHRINKED TO 300 AND THE COUNT IS STILL DECREASIING ...WHAT WOULD WE DO WITH THE SKYSCRAPERS WITH A BARREN LANDSCAPE ..NO GREENERY,NO LAKES,NO BIRDS, ...A CITY WITHOUT ITS BREATHERS .....A CITY WITHOUT A SOUL.
