Feildes Weir

The weir marks the start of the Lower Lee.

The weir has had a complex history of changes to channel control and bypassing over the years.

Control was originally exercised by a barrage of gates and sluices.

In 1976, a 29 metres (95 ft) wide thin-plate weir was installed, with three vertical-lift sluices controlling a parallel flood relief channel.

Flows average about 4.4 m3/s discharge over the weir; higher flows enter the flood channel.
