Lovat River
The whole of the district lies in the basin of the Lovat River. The Lovat crosses the district from south to north. The main tributary of the Lovat within the district is the Kunya (right). The town of Kholm is located at the confluence of the Lovat and the Kunya. The western part of the district is occupied by the Polist-Lovat Swamp System located at the border between the basins of the Lovat and the Polist Rivers. In the middle of the swamp, in the northwestern corner of the district, there is Lake Rdeyskoye, the biggest lake in the district and the source of the Redya River, a major left tributary of the Lovat. The Polist-Lovat Swamp System is protected as the Rdeysky Nature Reserve, which is shared between Kholmsky and Poddorsky Districts. 72% of the district's territory is covered by forests.
