Project summary

Edit project overview to modify the project summary.

The River Test is a chalk stream renowned worldwide for its excellent trout fly fishing. The reaches of the Test flowing through the Bossington Estate have been dredged and impounded by weirs leaving them wide, deep and silty with resulting low velocities and poor fish stocks.

Cain Bio-Engineering Ltd. produced designs for the five reaches that flow through the Bossington Estate. In partnership with the Estate and the Environment Agency, Cain Bio-Engineering Ltd. supervised the installation, based on 450m of channel narrowing on the Old Station Beat. The restoration was constructed using a variety of techniques, including woody deflectors and gravel fronted berms.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.

The restored reach provides a range of flow velocities and habitats with a reported increase in wild brown trout and a reduction in the Estate’s necessity to stock. The pre and post-restoration macro-invertebrate communities have been monitored by Southampton University, with results expected in Autumn 2014.
