Site description The area includes Servech Lake and part of the Servech river floodplain. The lake covers 450 ha, and has an average depth of 2.8 m. The waterlogged south-western part of the lake is the origin of the Servech river. The width of the channel varies from 2-5 to 15-25 m within the zakaznik. The floodplain is 1-2.5 km wide. The area is located close to the watershed of the Nioman, Western Dvina, and Dnieper rivers. The Servech river flows into Vileika water reservoir and is one of the main elements defining the water balance of the Vileika-Minsk water system.

Key Biodiversity In 2001 two bird species were found, both globally threatened: Aquatic Warbler Acrocephalus paludicola and Great Snipe Gallinago media. This is the northernmost known point of the Aquatic Warbler's range in Belarus. Other rare species known to occur are Bittern Botaurus stellaris and Common Crane Grus grus.

Non-bird biodiversity: Several rare plant species have been recorded, including Betula humilis, Salix lapponum, Carex lepidocarpa, Carex chordorrhiza, Dactylorhiza ochroleuca and other.
