Děhylov weir, Water control structure on Opava River, Czech Republic.
Děhylov weir is a water control structure built across the Opava River to regulate water flow through a series of monitoring installations. The facility manages river discharge and enables coordinated water management across the surrounding area.
The weir was built as part of regional infrastructure development to prevent flooding and enable controlled water use. Since its completion, it has played a key role in managing water resources in the Opava river system.
The weir functions as a central gathering point for local fishing communities while supporting agricultural practices through controlled water distribution in the Opava District.
The best time to visit is during spring and autumn when water levels are moderate and conditions are stable. It is easiest to reach by car, with parking available near the structure.
The weir uses an array of sensors that continuously record water volume and temperature data. This information feeds into a regional system that helps predict and respond to flood events across a broader area.
