Russian proverb AKE PEIPSI/CHUDSKOE-PSKOVSKOE, a transboundary lake that discharges into the Baltic Sea, is shared by Estonia and the L Russian Federation, both of which are responsible for its management. There is abundant water to meet the needs of an ageing, essentially rural, local population. However, uncontrolled fishing, eutrophication and pollution from untreated wastewater and power plant emissions have put the environment under increasing pressure. A joint water commission was created in 1997, but so far the economic potential of the area is underexploited, and more could be done to engage local and regional authorities, stakeholders and private businesses in solving common problems. Many changes will have to occur in 2004/5, as Estonia must adopt new standards in order to gain entry to the European Union.

Its L three names originate from the three languages historically used in the region – Estonian, Russian and German. Lake Peipsi belongs to the Atlantic watershed of the Narva River, a 77 kilometre (km)-long watercourse that Ocean RUSSIAN FED. connects Lake Peipsi to the Gulf of Finland in the Baltic Sea.

Lake Peipsi is located on the border of the Republic of Estonia and the Russian Federation between Lake Peipsi lowland (eastern border of Estonia) and the East European Plain (the Russian Federation).
