Latvia generally does not have a water shortage problem as annual precipitation exceeds evaporation by 250 mm, in humid years even by 500–600 mm.
There are more than 12,400 rivers and 2,256 lakes in the state, which together with water reservoirs cover 3.7% of the state territory.
Wetland ecosystems, which have been destroyed in most of Europe, make up to 10% of territory of Latvia.
