[2] RK Puram lake's also Known as Mukidigan Cheruvu (Original Name) roots can be traced back to 1798 when the 'subsidiary alliance' was proposed by then British Governor-General in India, Lord Wellesley.

The engineers and electricians who worked here needed water, So RK Puram Lake was commissioned by the Nizam and dug up in the mid-1800s, occupying a space of around 100 acres.

[3] There is no established date for when the RK Puram lake was dug up, but its roots can be traced back to 1798 when the 'subsidiary alliance' was proposed by then British Governor-General in India, Lord Wellesley.

As part of the alliance, the East India Company offered protection to the rulers of princely states, in exchange for money or land.

At this time, Secunderabad was a small taluk, described as a low flat ridge, near a village north of the Hussain Sagar Lake.

The lake remained a major source of drinking water and largely clean, until the late 1960s, when the Electronics Corporation of India Limited (ECIL) was established.
