Ba Bể Lake

Ba Bể Lake (, Ba Bể meaning "Three Lakes" in the local Tay language) is the largest natural fresh water lake in Vietnam, stretching about 8 kilometers in the north-south direction. The surface area of the lake fluctuates between 3 and 5 km² between dry and wet season. Unlike many lakes in

areas, Ba Bể Lake never falls dry. Its average depth varies between 17 and 23 meters, the maximum depth is 35 meters. The lake lies about 150 meters above sea level, making it also Vietnam's highest lake. The name "Three Lakes" refers to the three parts of the lake named Pe Leng, Pe Lu, and Pe Lam. All these three parts are connected into a single continuous body of water, however. The Ta Han, Bo Lu, and Leng Rivers feed into the lake from the south and the west. During the dry season, water is drained from the lake northwards into the Nang River. During high floods in the wet season, the latter flow is reversed however, and the lake takes up water from the Nang River thereby acting as a buffer regulating flooding.

Flora and fauna

The vegetation in Ba Bể National Park mainly consists of limestone and evergreen forest. The former covers steep mountain slopes on which the soil cover is thin. The latter depends on thicker soil cover and has a higher species diversity. The dominating tree species of the limestone forest are '' Burretiodendron hsienmu'' (
