Lake Venado is one of smallest lakes of the Philippines located at the foot of Mount Apo in Mindanao. It is elevated at 1,294 meters above sea level. Due to its elevation heights, the water in the lake is freezing cold which could cause cramps on the swimmer.
 Incidents and Accidents
In April 2007, Ian Caasi - a mountaineer swimming in the lake, drowned. His fellow mountaineers were prevented from rescuing him due to the lakes freezing temperature.
