The competition of Chundan Vallams (snake boats) known as Vallam Kali (boat play/game )held on the second Saturday of August every year at Punnamada Lake near Alappuzha is popularly known as Nehru Trophy Boat Race . In 1952, when the prime minister of Independent India Pandit Jawarlal Nehru visited Alappuzha was treated with a roaring reception by the people of Alleppey, escorted by the huge snake-boats and a snake boat race was conducted in Punnamada Lake for him. Excited and thrilled by this performance, Jawaharlal Nehru, who forgot all security arrangements for him, jumped into the snake boat which won the first and donated a rolling trophy to be awarded to the winner of the race. On his return to Delhi, Nehru’ji sent a trophy to the winner team which is a replica of a snake-boat in silver, placed on wooden abacus. In the fond memory of Jawaharlal Nehru’s visit, the trophy was renamed as Nehru Trophy in the year 1969. Around 100-120 feet long canoes made of wild jack wood which carry 90-110 rowers and moves like a snake through the channels at a course of 1.4 km(0.9 Miles) is a fest to eyes of visitors.
