Project summary

Edit project overview to modify the project summary.


Haltwhistle Burn: ‘a total catchment’ approach is a partnership project which will use CRF funds to improve the whole catchment which has suffered the pressures of quarrying, farming, industry and an increasing population. Although the ‘official’ reasons for failure concern pressures on fish according to the criteria provided by the Water Framework Directive (WFD) this project addresses total waterbody issues deriving from a multitude of pressures, each creating ‘sub-lethal’ but chronic stresses. Haltwhistle’s ‘Centre of Britain’ identity, together with attraction of Hadrian’s Wall makes it a po-tentially significant tourism centre, with a focus on both heritage and natural features. There are however significant economic difficulties and youth behaviour issues. Haltwhistle Burn is a central focus and has already attracted works of improvement and interpretation by the Haltwhis-tle Partnership. Since the 2007 floods in the town, Tyne Rivers Trust has nurtured excellent relationships with agencies and extremely enthusiastic individuals directly connected to their catchment. Whilst the project is not a flood defence project this CRF funding now gives us a clear focus for agency action and direct spending on mitigating excess runoff and pollution.

Tyne Rivers Trust have already carried out geomorphological and habitat assessment of the entire burn, concluding that the ‘catchment approach’ would, by combining the small issues, create a significant benefit for the South Tyne and address the WFD ‘poor status’ classification.

Social measures (incl. engagement) Increase awareness of flood issues
Other Community engagement with, and responsibility for, the delivery within every strand of this project will be encour-aged. A Tyne Rivers Trust River Watch group has already been set up collating existing local knowledge, carrying out some improvement tasks such as tree planting and to achieve monitoring via fixed point photography, inverte-brate analysis, electro-fishing, and rainfall and flow measurements. The local school has also experiences a ‘Living Rivers’ day with Tyne Rivers Trust exploring their local burn and issues of the wider catchment. They will be further engaged as the project develops.
