Incidentally, Nebu is a regular contributor to the ‘Time Out’ feature of the New Indian Express.
According to Wikipedia, The Ponnozhukum thodu, ‘flows through Elikkulam, Mallikassery, Vilakkumadam, Edamattom regions and joins the Meenachil near the Shree Krishna Swamy temple, Bharananganam’. I have not found out where it originates.
View downstream. The Thodu looks narrower than I remember.
Obviously the reason is the granite retaining walls
which were not there earlier.
The water still looks clear though rather stagnant.
For me Ponnozhukum Thodu is a stream of memories.
