Podhora Reservoir, lake in Ovesné Kladruby, Karlovy Vary Region, Czech Republic

Podhora Reservoir is a water storage basin near Ovesne Kladruby in the Czech Republic, formed by a straight earthen and stone dam. The structure extends about 280 meters in length and rises over 10 meters high, holding more than three million cubic meters of water for the surrounding region.

The pond was originally created by Teplá Abbey as a fishpond. Its dam burst during the flood of 24 November 1890, causing major damage in the town of Teplá. Between 1952 and 1956 the old Podhorský rybník was rebuilt as a drinking-water reservoir for the Mariánské Lázně area, with a pumping station added; a new pumping station followed between 1974 and 1982.

The reservoir's name comes from the Podhorní vrch (847 m) at whose southeastern foot it lies; the German name Podhornteich recalls its origin as a fishpond of the Teplá monastery. Today the Teplá river is dammed here to supply drinking water to the Mariánské Lázně area, and the railway line Mariánské Lázně–Karlovy Vary runs along the southern shore.

The reservoir lies 4 km southwest of Teplá and 8 km east of Mariánské Lázně, at 693 m on the southeastern foot of Podhorní vrch (847 m). The dam, 280 m long and 4.4 m wide, stands west above the village of Mrázov. The Mariánské Lázně–Karlovy Vary railway runs along the southern shore.

The reservoir was originally a fishpond of the Teplá Monastery, and its dam burst during the flood of 24 November 1890, causing major damage in the town of Teplá. The old Podhornteich was rebuilt as a drinking-water reservoir between 1952 and 1956.
