Project summary

Edit project overview to modify the project summary.


This project aims to improve the WFD status of all 15 water bodies in the Midlothian Esk catchment by easing barriers to migratory fish. It is at the first stage of gathering information and scoping out what easements are possible.

The project is funded by the Water Environment Fund. The first phase of the project involves scoping studies on the main barriers in the system, and planning a phased approach to barrier easements over the 2nd River Basin Planning Cycle.

All 15 water bodies in the Midlothian Esk catchment are downgraded to poor for fish passage, where there are 8 known barriers for fish migration. All barriers are high up SEPAs priority list: the priorities range from number 7 to number 16 on the list.

At least 41 other weirs occur within the catchment and these will also be visited to ensure there are no other barriers missed: it is highly likely that some of these will prevent fish migration.
