No
Old railway crossing prior to demolition

Project summary

Edit project overview to modify the project summary.


Abandoned railway criss crossed the R Derwent at three locations at this vicinity. The failing abutments and buttresses were removed summer 2013 to improve stream hydrology and morphology.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.


River morphology recovering well. No negative impacts from subsequent major flood events including 'Storm Desmond' December 2015

Lessons learnt

Edit project overview to modify the lessons learnt.


Undertake a Level 2 archaeological survey prior to demolition Ensure landowners and fishery owners are on board in the early stages Evaluate likely channel impacts from proposed modifications prior to demolition so no significant supprises
