Manimala River, or
Manimalayar, is a 92km long river which flows through South and Central Kerala. The river used to be wrongly considered as a tributary of Pamba River before satellite maps became popular, but this was proved incorrect. Manimala does not flow into the Pamba, instead a distributary of the Pamba river flows into the Manimala river at Kallunkal, later branches out again from Manimala at Nedumpuram and flows through Niranam, Thalavady, Edathua, Changankary, Champakulam, Nedumudy, Chennamkary, and finally Kainakary and then empties into the Vembanad lake. This branch again links with the Manimala River at Chennankary in a short, but broad connection known as Munnattumukham.
