Physical Characteristics

Description Peipsi is a shallow lake and is comprised of three parts: Lake Peipsi itself (2610 km2), Lake Pskov (710 km2) and the narrow but deep Lake Lämmijärv (235 km2 deep but only 3 km wide at the smallest crossing), which connects them. In Lake Lämmijärv lies the deepest place in Peipsi - 15.3 m.

The volume of the lake is twice as much as the annual runoff of the Estonian rivers. In spring Peipsi's water level can rise by almost a meter. At its highest level the area of the lake increases by 780 km2. In October the level of water is at its lowest.

There are 30 islands in the lake. The biggest - Piirissaar belongs to Estonia. (A. Jaani et al, 1998).

The Narva River Basin that feeds Lake Peipsi flows through Estonia, Russia and Latvia. However, Latvia contributes little to the overall pollution within the watershed.

Lake Peipsi is a eutrophic and biologically highly productive lake. The Peipsi basin forms 85% of the Narva-Peipsi watershed (56 225 km2), which is 47 814 km2.

Ice cover on Peipsi usually forms at the end of November. It will be thickest, up to 50-60 cm, in the second half of March.

Socio-Political

Economic Value Commercial fisheries and agriculture are the most important sources of income for the local population within the region. Fisheries supported by Lake Peipsi include lake smelt, perch, ruff, roach, bream, pike, vendace and pikeperch.
Major Cities Pskov (Russia) has 203,000 inhabitants and Tartu (Estonia) has 98,000 inhabitants. The remainder of the population within the watershed lies in small settlements. (LBMI 2003)
Population 1,000,000 (2003)

Watershed Management

Description Under a UNDP/GEF project, a Lake Peipsi Basin Management Program will be developed by the Estonian-Russian Transboundary Water Commission and authorities in each country. A feasibility study is being conducted on the development of water and ecological tourism in the Lake Peipsi region. There are plans for the establishment of two Lake Peipsi museums, one on the Estonian side of the lake and one on the Russian side.
Watershed Action Plan In development
Issues Nutrient pollution is a major threat to water quality in the lake; fortunately recent years have shown a tendency for the better. The main source of this water pollution is agriculture and municipal wastewaters.
