Lake Trasimeno
Lake Trasimeno (Italian: Lago Trasimeno, Italian pronunciation: [ˌlaːɡo traziˈmɛːno]; Latin: Trasumennus; Etruscan Tarśmina), also referred to as Trasimene or Thrasimene in English, is a lake in the province of Perugia, in the Umbria region of Italy. The Lake is located in the south of the Po River and to the north of the nearby Tiber River, has a surface area of 128 km2 (49.4 sq mi) and it is the fourth for surface in Italy (it is slightly smaller than Lake Como). Only two minor streams flow directly into the Lake and none flows out. The water level of the lake fluctuates significantly according to rainfall levels and the seasonal demands from the towns, villages and farms near the shore.
The lake
Trasimeno is shallow, muddy, rich in fish, including pike, carp, and tench. During the last 10 years has been 5 m deep on average. Lake Trasimeno is an endorheic body of water; it is an impounded lake that receives water but has no outlet. Other endorheic bodies of water include the Caspian Sea, Aral Sea, Utah's Great Salt Lake, and the Dead Sea. Evaporation can lead to a buildup of minerals in the water, resulting in saline conditions, making these lakes sensitive to pressures from pollution.
