Lovat River
The area of the district is divided between the drainage basins of the Lovat River (which belongs to the Neva River basin) and the Western Dvina River. The Lovat crosses the western part of the district from south to north, flowing from Belarus to Velikoluksky District. The biggest tributary of the Lovat in the limits of the district is the Kunya River (right),which flows to the east and crosses into Kunyinsky District. The central and the southeastern parts of the district belong to the basin of the Usvyacha River, a left tributary of the Western Dvina. The Usvyacha flows to the south, crossing into Belarus. The biggest lakes in the district are Lake Uzmen and Lake Usvyaty, both in the basin of the Usvyacha. The settlement of Usvyaty is located between these two lakes.
