Which Nallah? What Drain? Series: Colours of Ulsoor Lake.
On the left is the calmer, settling and aeration tank where the drain from Cox Town and beyond empties into the Ulsoor Lake. In this separated area of the lake, the muck is allowed to settle and a series of fountains aerate the water. Using gravity, and depending on the flow into the lake, the water slowly spills over a separation wall (shown in the above picture). However, enough nutrients spill over to feed the green algae of the Ulsoor Lake proper (that is seen on the right).
And that's Muniraju fishing on the green side. He catches enough fish everyday to make a living. The fish that will make its way back to a pot in Cox Town, completing a cycle and harvesting what we sow.
