Мста
The western part of the district lies in the basin of the Msta River, with its main tributary within the limits of the district being the Uver. The eastern part belongs to the basin of the Mologa. The principal river in the basin of the Mologa on the territory of the district is the Kobozha. Since the Msta belongs to the basins of the Volkhov River and the Baltic Sea, whereas the Mologa drains to the Volga and the Caspian Sea, the divide between the Caspian Sea and the Atlantic Ocean crosses the district from north to south.
