From the google map when I searched this is named as RBI layout lake. The actual name of this lake is Subbarayara kere.
I wanted to go to Arekere from ISRO layout and on the way I found this lake. There is green water in this lake in some area and might be upto four feet deep. Actually a man was walking inside this water and was waist deep. Seriously I could not figure out what exactly he was doing as the water wasn’t clean at all. But this lake is fenced and is a protected property now.
