Lovat River
The area of Andreapolsky District is shared between the drainage basins of the Neva, the Western Dvina, and the Volga, and thus the divide between the basins of the Atlantic Ocean and the Caspian Sea runs through the district. The northwestern part of the district belongs to the drainage basin of the Lovat River, a major tributary of Lake Ilmen. The rivers in the central part of the district drain into the Daugava, or the Western Dvina as it is known in Russia. The source of the Western Dvina is located in the district. This area contains a large lake district in the southwestern outskirts of the Valdai Hills. The biggest lakes are Lake Luchanskoye and Lake Brosno. The southeastern part of the district belongs to the drainage basin of the Zhukopa River, a tributary of the Volga.
