## Geography

The district lies in the southeastern part of the Valdai Hills and is split between the drainage basins of the Baltic and Caspian Seas. The rivers in the western part of the district drain into the Msta, a major tributary of Lake Ilmen, which belongs to the basin of the Neva and thus of the Baltic Sea. The Msta itself crosses the southwestern part of the district and makes a stretch of the border between Udomelsky and Bologovsky Districts. The central and the eastern parts of the district belong to the basin of the Mologa, a tributary of the Rybinsk Reservoir in the basin of the Volga which drains into Caspian Sea. Udomelsky District is a part of the lake district located in the Valdai Hills, with the largest lakes within the district being Lake Udomlya, Lake Pesvo, and Lake Navolok, all in the drainage basin of the Msta. Most of the district area is covered by forest.

## History

The area of the district was originally populated by the Finnic peoples, in the 11th century, Slavs started to arrive. Until the 15th century, the area belonged to the Novgorod Republic, and subsequently, together with Novgorod, it was annexed by the Grand Duchy of Moscow. The area belonged to Bezhetsk Pyatina, one of the five pyatinas into which Novgorod Lands were divided.
In the course of the administrative reform carried out in 1708 by Peter the Great, the area was included into Ingermanland Governorate (since 1710 known as Saint Petersburg Governorate), and in 1727 Novgorod Governorate split off. In 1775, Tver Viceroyalty was formed from the lands which previously belonged to Moscow and Novgorod Governorates. In 1770, the area was included into Vyshnevolotsky Uyezd of Tver Governorate, and between 1775 and 1796 it belonged to Tver Viceroyalty, which was subsequently transformed back to Tver Governorate. In the 1870s, the railroad was open, which led to quick development of the area.
On July 12, 1929 the governorates and uyezds were abolished. Udomelsky District, with the administrative center in the railway station of Udomlya, was established within Tver Okrug of Moscow Oblast. On July 23, 1930, the okrugs were abolished, and the districts were directly subordinated to the oblast. On January 29, 1935 Kalinin Oblast was established, and Udomelsky District was transferred to Kalinin Oblast. In January 1961 Udomlya was granted work settlement status. In February 1963, during the abortive administrative reform by Nikita Khrushchev, Udomelsky District was merged into Bologovsky District, but in January 1965 it was re-established. Between 1974 and 1984, the Kalinin Nuclear Power Plant was constructed. On September 11, 1981 Udomlya was granted town status. In 1990, Kalinin Oblast was renamed Tver Oblast.
On June 1, 1936 Brusovsky District with the administrative center in the settlement of Brusovo was established as a part of Kalinin Oblast. On November 14, 1960 it was abolished and split between Maksatikhinsky and Udomelsky Districts.
