Derwent Projects

The East Yorkshire Rivers Trust co-ordinates and participates in a wide range of projects to improve the fisheries and biodiversity of rivers within their catchment. A selection of projects completed on the River Derwent can be seen below. For further information on the Trust's recent activity why not read our recent newsletter.

 

£12m Salmon Fishery for the River Derwent

A scheme to allow salmon and sea trout back in to the River Derwent for the first time in 40 years aims to create Yorkshire's most valuable fishery – worth at least £12.5 million a year. A barrage on the River Derwent, at Barmby on the Marsh, will be opened eight hours a day from May 24, allowing thousands of salmon and sea trout migrating along the Ouse from the sea to enter the 72-mile river and its tributaries. Further details.

 

Hertford Workshop

Hertford rehabilitation workshopThe East Yorkshire Chalk Rivers Trust in partnership with the Environment Agency and Wild Trout Trust, collectively organised and ran a two day workshop demonstrating habitat enhancements for maintained river and drainage channels. The workshop showcased techniques that can be employed to create self-maintaining river channels and improve habitat quality, with minimal impact upon flood conveyance. Further details.

 

Costa and Pickering Beck Channel Restoration

EA work day

The Costa is a “failing water body” as designated under the Water Framework Directive and the Environment Agency has been working with all interested parties to reverse this state of affairs.

The Costa Project has been in progress for some time now but is at the stage where willing hands were needed and these members of staff volunteered their “Environmental Leave Day” to help out. Further details.

 

Pickering Beck Channel Restoration

EA work dayPickering Beck is fed from the NorthYorkshire Moors. It follows a meandering course alongside the North Yorkshire Moors Railway as it approaches the town of Pickering from the north. Part of this course is within a SSSI and the boundaries of the North York MoorsNational Park.

The aims of the project are to use large woody debris (LWD) and coarse woody debris (CWD) to stabilise the bed of the stream. This will also provide much needed habitat for small fish and invertebrates. Further details.

 

‘Straightened’ Derwent Project

Straightened DerwentThe proposed project is to invest in a trial length of the straightened river, approximately 1½ km and address the lack of morphology by using recognised river mending techniques and green engineering methods to benefit the geomorphology of the river.

We will monitor the effects on both the WFD failures as well as any land drainage and flood defence issues. If, after the first year, all parties are agreeable, it is then suggested that the 1½ km trial site be rolled out on straightened River Derwent and River Hertford. Further details.

 

 

Scalby Beck Fish Pass Project

Scalby beck fish pass

Over 100 years ago a man-made channel was cut from the headwaters of the Derwent to Scalby Beck to take flood water and discharging into the North Sea. As part of the flood relief channel a number of weirs have been built to manage the energy of the floods. These weirs are a barrier to upstream migration for salmon, sea trout, eels and lampreys.

Scalby Beck Angling Club with the help of EYRT succesfully replicated their “home-build” fish pass to improve the passability for salmon and sea trout. Further detaiC
