Hanover Weir Rock Ramp Fish Pass Scheme

Client:
Inland Fisheries Ireland

The weir has been chosen by Inland Fisheries Ireland for remedial works due to an ongoing issue with the existing fish pass facility at the weir. The weir was inspected by the Inland Fisheries and The Department of the Environment, community and Local Government which confirmed that the fish pass at the weird is not effective in providing the free movement of all fish over all periods of the year as stated in Section 116 of the 1959 Fisheries (Consolidation) Act of the requirements of the European Habitats Act. It is proposed to construct a rock ramp type fish pass immediately in front the existing weir. The footprint of the ramp is 13m wide x 50m long. The weir crest will be lowered by 600mm.

The Works incorporate the following:
  Review of information of existing services regarding planning and execution of the works.

Installation of Environmental Mitigation Measures.
