3 valleys

Bengaluru is situated at approximately 3000 feet above mean sea level. When it rains unless the water is retained the rain water will flow down to lower levels. When Three generations of Kempegowdas built layered lakes they kept this aspect in mind, hence they interconnected the lakes through an excellent network of canals called Rajkaluves so that when the lakes in higher elevations filled out then the water flowed to the lakes in lower elevation.

To understand Bengaluru’s water management system, it is important to understand the city’s topography. Bengaluru has three major natural valley/drainage zones, and three minor ones. The major valleys are Vrishabhavathi Valley, Koramangala-Challaghatta Valley and Hebbal Valley. The minor valleys are Tavarekere, Kathriguppe and Arkavathi.

When these valleys are blocked by mindless town planning or lack of it.. and aided by highly corrupt combination of political, bureaucratic lobby and greedy real estate thugs then where does water go ?

Overflowing lakes

This small news column in #VK sums up everything about #BengaluruFloods.

Mahadevapura has 63 lakes. ALL are overflowing. So any low lying area there is in danger.
Halanayakana Halli lake (70 hectares) has overflown after 40 YEARS. This water has to reach Soul lake. But Rainbow Drive layout is blocking it. Hence it is flooded. You would have seen 100 videos.
Since Soul Kere is overflowing, the Ecospace IT park is flooded. Soul lake overflow has to reach Bellandur lake. But Ecospace has blocked the floodplain path. Hence water is flowing to Outer Ring Road. This is where 1000 videos were made and even drone footage was sent across the world.
In KR Puram, Vibhutipura lake is overflowing. Sai Layout flooded.

All manmade due to greed of Real Estate tycoons and gullible buyers who wanted a big profit quickly 😟 All within two zones of Bengaluru, while more than 80% of the city has almost normal life.
