Weir

There was a weir across the river here, but it never caught many fish.

Circular water currents at the base of a weir can trap people, causing them to drown.

The dam design includes an emergency spillway weir, to handle flood flows without risking erosion on the rest of the embankment.

In summing up, Judge Reginald Weir said he was critical of forensic evidence presented by the prosecution that relied heavily on a new kind of DNA testing. He also criticized the police for how they handled and stored the evidence, with possible cross-contamination.

The lock on the weir was released for the boat to pass through.

Though Hambleden's parish register records the death, in 1753, of a bargeman 'Kill'd by accident, shooting ye lock', the turbulent waters of Mill End weir on the River Thames, about a mile from the village, still attract canoeists.

The weir must not represent a physical barrier to fish migration, both locally and throughout the whole river system. If necessary, a fishway is included in the weir.

A walkway over the weir is likely to be useful for the removal of floating debris trapped by the weir, or for working staunches and sluices on it as the rate of flow changes.

The Taff is naturally a good salmon river, the Ely a sea trout river, but what with weirs and pollusions the fish have been pretty well exterminated.

The weir catch of mackerel at Monomoy and along Cape Cod has been a failure.
