Újezd Reservoir, lake in Vrskmaň, Ústí nad Labem Region, Czech Republic

Újezd Reservoir is a reservoir on the Bílina in the Most Basin, built 1978–1981 to replace the Dřínov reservoir. Its straight earth dam is 1,768 m long, up to 13.9 m high and 9 m wide at the crown, which carries the road from Vrskmaň to Vysoká Pec. The water surface covers 152.1 ha and holds up to 8.4 million m³.

Built between 1978 and 1981 by the Wasserbau Chomutov company as a replacement for the Dřínov reservoir, it went into operation in 1981 and the Bílina riverbed was relocated at the same time. The village of Újezd, which gave the reservoir its name, was flooded, and the village of Kyjice was demolished to make way for the 13.9 m dam on the eastern shore.

The name Újezd comes from old Czech and refers to land marked out by noblemen. The village that once stood here was a farming community with crafts and small workshops, now submerged beneath the reservoir's surface.

The dam crest, 1,768 m long and 9 m wide, carries the local road from Vrskmaň to Vysoká Pec, so the reservoir can be crossed on foot or by bike. The Ústí nad Labem–Chomutov railway crosses the water on a viaduct, and road I/13 runs along the western and northern shores.

The dam's crest carries the local road between Vrskmaň and Vysoká Pec, and the railway line from Ústí nad Labem to Chomutov crosses the reservoir on a viaduct. The reservoir was built as a replacement for the Dřínov reservoir and began operating in 1981.
