Poddorsky District in the context of Poddorye

The Lovat (Belarusian: Ловаць, romanized: Lovac', IPA: [ˈɫovatsʲ]; Russian: Ло́вать) is a river in Vitebsk Oblast of Belarus, Usvyatsky, Velikoluksky, and Loknyansky Districts, as well as of the city of Velikiye Luki, of Pskov Oblast and Kholmsky, Poddorsky, Starorussky, and Parfinsky Districts of Novgorod Oblast in Russia. The source of the Lovat is Lake Lovatets in northeastern Belarus, and the Lovat is a tributary of Lake Ilmen. Its main tributaries are the Loknya (left), the Kunya (right), the Polist (left), the Redya (left), and the Robya (right). The towns of Velikiye Luki and Kholm, as well as the urban-type settlement of Parfino, are located on the banks of the Lovat.

From the source, the Lovat flows in the southeastern direction along the border between Russia and Belarus, it turns north and enters Pskov Oblast of Russia, crossing the border as Lake Sesito. In this area, the Lowat flows through the lake district, passing, in particular, Lake Vorokhobskoye. Downstrean of Velikiye Luki, in the selo of Podberezye, the Lovat turns northwest and enters Novgorod Oblast. Close to Lake Ilmen, the Lovat shares a river delta with the Pola and the Polist, though technically Polist is counted as a tributary of the Lovat.

The Polist (Russian: река́ По́листь) is a river in Bezhanitsky District of Pskov Oblast and in Poddorsky and Starorussky Districts, as well as in the town of Staraya Russa of Novgorod Oblast of Russia. It is technically a tributary of the Lovat though it forms a common river delta with the Lovat and the Pola at the mouth of the Lovat in Lake Ilmen. It is 176 kilometres (109 mi) long, and the area of its basin 3,630 square kilometres (1,400 sq mi). The principal tributaries of the Polist are the Kholynya (left) and the Porusya (left). The town of Staraya Russa is located on the banks of the Polist.

The source of the Polist is in Lake Polisto in the east of Pskov Oblast, in the western part of the Valdai Hills. The upper course of the Polist is located in the Polist-Lovat Swamp System, one of the biggest raised bog areas in Europe. The Polist flows northeast, enters Novgorod Oblast, and joins the Lovat at its delta.

The Redya (Russian: Редья) is a river in Kholmsky, Poddorsky, Starorussky, and Parfinsky Districts of Novgorod Oblast in Russia. It is a left tributary of the Lovat. It is 146 kilometres (91 mi) long, and the area of its basin 671 square kilometres (259 sq mi).

The source of the Redya is in Lake Rdeyskoye in Kholmsky District. The upper course of the river, including Lake Rdeyskoye, is located within Rdeysky Nature Reserve, which is a vast swampy unpopulated area. The Redya flows northeast. Several initial kilometers of its course are located in Kholmsky District, after which the Redya crosses over to Poddorsky District. The district administrative center, the selo of Poddorye, is located on the left bank of the Redya. Downstream of Poddorye, the Redya crosses into Starorussky District. In this area, the Redya is one of many sizeable rivers flowing northeast over the Ilmen Depression, towards Lake Ilmen. The course of the Redya is confined between the courses of the Lovat (east) and the Porusya (west). For approximately 20 kilometres (12 mi), the Redya forms the boundary between Starorussky and Parfinsky Districts. In its lower course, it departs from the boundary back into Starorussky District and joins the Lovat, forming a joint delta with the Lovat, the Pola, and the Polist.
