The River Wensum

Project summary

Edit project overview to modify the project summary.

In the past this section of the Wensum at Bintree Mill has been dredged creating a deepened and overwidened channel with uniform flow, and has suffered from over-grazing and trampling by Limosin cattle. The Bintree Angling Club had ownership of the fishing rights of this stretch of the river and implemnted habitat improvements that to promote wild brown trout fishery with less reliance on stocking. This was achieved through channel narrowing, riffle installation, fencing, flow deflectors, tree planting and the creation of fenced cattle crossing points.
