This wide-swath ASAR image shows Lake Peipus, the biggest transboundary lake in Europe, on the border between Estonia and Russia, and south of the Gulf of Finland.
The lake is the fifth largest in Europe after Lake Ladoga and Lake Onega in Russia, Lake Vänern in Sweden, and Lake Saimaa in Finland. It covers 3,555 km2, and has an average depth of 7.1 m, the deepest point being 15 m.
The lake has several islands and consists of 3 parts: Lake Peipsi/Chudskoe, the northern part of the lake with the area of 2611 km2 (73%); Lake Pihkva/Pskovskoe, the southern part of the lake (area 708 km2 or 20%); and Lake Lämmijärv/Teploe, the sound connecting both parts of the lake (area 236 km2 or 7%).
Some 30 rivers and streams discharge into Lake Peipus. The largest rivers are Emajõgi and Velikaya River. It is drained by the Narva River. The lake is used for fishing and recreation, but suffered from some environmental degradation from Soviet era agriculture.
