Weir Pržno, Water management structure in Pržno, Czech Republic

Weir Pržno is a reinforced-concrete weir on the Ostravice river at river kilometre 32.97, just upstream of the Frýdlant–Pržno road bridge in the Moravian-Silesian Region. Its crest is 60 m wide and 3.65 m high, with a bent bypass channel at the left bank that turns right.

The sources document the weir only in its present form: a reinforced-concrete structure on the Ostravice at river kilometre 32.97, 3.65 m high with a 60 m crest, operated by the state enterprise Povodí Odry. No construction date or historical development is recorded, so its history cannot be given beyond its current role in managing the river's flow.

The weir is a rescue point on the Ostravice, marked FM 108 and equipped with a lifebuoy, one of the safety points along the river. Canoeists cannot run the weir; they use the angled bypass channel at the left bank, which turns right, to drag or carry their boats around it. Cycling route 59 passes the weir.
