W: Water Resources
Water Resources - Belarus has about 21 thousand rivers and creeks totaling 90.6 thousand km in length and 11 thousand lakes, 470 of them exceed an area over 0.5 km2 each. Water bodies cover 2% of the country’s area. The largest lake in Belarus is the Naroch lake (79.6 km2, maximum depth about 25 m). Over half of Belarusian water resources (56%) account for the Black Sea basin, the remaining fraction for the Baltic Sea basin. The rivers of Prypyat, Dnieper, Neman, Berezina and Western Dvina and also the Dnieper-Bug Canal are most critical for navigation.
145 water storage reservoirs were built in Belarus. Of critical importance is the Vileiskaya storage water reservoir (75 km2). The Vileisko-Minsk water system, through which water of the Viliya river is supplied to Minsk, originates from it.
Renewable resources of fresh surface waters and groundwater available in the country are sufficient to meet current and expected demand in water: river water resources amount to 57.9 km3/year. The total water volume accumulated in lakes is estimated at 6–7 km3 and the storage volume of water storage reservoirs is estimated at 3.1 km3. The public water supply abstraction is less than 5–7% on the average of annually renewable water resources.
