The swift growth of the city swallowed up most small and medium-sized lakes. Urbanization has converted many lakes into the bus station and stadium layouts and apartment complexes. Encroachment has made small lakes disappear without any trace. Huge trees have also vanished along with lakes. The natural air-conditioned weather in Bengaluru heating up is an example of global warming.

In fact, the city of Bengaluru –which had no other natural water sources –grew and expanded because of lakes. The same lakes are now dying a slow death due to rapid urbanization. Lakes were built with the main intention of supplying drinking water for domestic use, agriculture and dairy farming. The presence of lakes helped in retaining high water levels in the villages around Bangalore. It is indeed tragic that the lakes have now become sewage collection areas.

The very few remaining lakes and tanks of Bengaluru are in a highly polluted condition. They are fast being encroached upon. One well known beautiful lake that is now in a bad state is Hosakerehalli Lake. It has become a garbage dump yard. Decades ago, this was a life-giving source of water for the surrounding villages. Now, it is on the verge of being damaged beyond repair. There are no aquatic fauna, birds or any creatures around the lake. Hosakerehalli village was known for dairy farming.
