Remember those days when we were taught about different types of body of waters? Of course, lake is one of the list. Lake is defined as a large body of water surrounded by land. Several lakes can be found in our country and among the lakes which are known in the Philippines are Laguna de Bay,the largest lake, and Taal Lake situated in Luzon and Lake Lanao in Mindanao. Our country has 59 lakes and the origin of most lakes is a result of volcanic and tectonic activity.
