Lipno II Reservoir, balancing reservoir in Vyšší Brod, Czech Republic

Lipno II Reservoir is a balancing reservoir on the Vltava at the edge of Vyšší Brod, built to even out discharges from the Lipno I plant 4 km upstream and 160 m higher. Its dam is 224 m long and 11.5 m high, combining an earth-fill section with clay sealing core and a concrete gravity section holding two gated crown spillways, a siphon spillway and the intake of the Kaplan-turbine power plant.

Construction of the dam began in 1952 and finished in 1959, though an older power plant had operated at the site from 1902 until the 1950s. The new system with the dam and reservoir improved both water management and electricity generation significantly.

The reservoir's name distinguishes it from the much larger Lipno I upstream; locals call only that main lake the 'South Bohemian Sea'. Near the dam, a small power plant operated from 1902 until the 1950s before the current reservoir was built. The railway station Vyšší Brod klášter lies directly below the dam on the Rybník–Lipno nad Vltavou line.

The dam lies on the Vltava at the edge of Vyšší Brod, with the Vyšší Brod klášter station on the Rybník–Lipno nad Vltavou line directly below it. The 224 m long, 11.5 m high dam combines an earth-fill section and a concrete gravity section. Since 1996, a minimum flow of 1.5 m³/s has been released into the 9 km stretch of river between the two plants.

The system uses an underground connection where water from the upstream Lipno I plant flows into this reservoir and then exits along the riverbank again. This innovative design allows continuous power generation without disrupting the natural river flow itself.
