Zdymadlo Lysá nad Labem

Zdymadlo Lysá nad Labem is a lock on the Elbe River that helps boats move between different water levels while managing the flow of the river. The installation combines a navigation chamber, weir structure, and hydroelectric facilities that work together to control water levels.

Construction of this lock began in 1931 as part of a major Elbe River regulation project. The hydroelectric component was added later and started operating in 1948 after wartime delays.

The lock represents Czech engineering excellence in water management, combining navigation infrastructure with renewable energy production through its hydroelectric power station.

Boat operators can communicate with lock personnel via radio to coordinate passage through the facility. The lock operates during daylight hours and weather permitting, so check local conditions before visiting with a vessel.

The facility includes a fish passage that runs alongside the main lock, allowing river fish to migrate between different water levels without going through the main chamber. This feature is built into the weir structure and supports the local ecosystem.
