"The Dewsbury Flood Relief Channel (further down the river) is expected to flood.
The existing flood relief channel has been improved so that it can cope with more water during a flood.
The second phase will also involve installing a penstock in the flood relief channel. This acts like a large moveable gate and it will restrict the flow of water towards Stanhope Gardens during high flows and reduce the flood risk.
Yet the town was threatened by the dangerously high level of the river just before Christmas resulting in the need to build an emergency flood relief channel.
A 1,600-ft (0.5-km) reach near the Skyway 14 Trading Estate was vulnerable to flooding, and the dense development of motorway and industrial/commercial uses around the stream precluded construction of a continuous flood relief channel. As a result, the capacity of the channel itself had to be increased.
Detailed designs for a pounds 250,000 scheme to reduce the risk, including the re-alignment of the Ormesby Beck at Kentmere Road and improvements to the flood relief channel, have been drawn up.
The route will use existing riverside paths, as well as a new path along the flood relief channel near Thornhill Road.
