Proposal for Carnoe Weir Refurbishment

Carnoe Row Weir from the air

Waterways Ireland is proposing to undertake extensive refurbishment works to the weir at Carnroe on the Lower Bann between Lough Neagh and Coleraine. 

Carnroe Weir is essential to the retention of water levels and boat movements along the length of the Lower Bann and  also provides a resource for the local  communities and visitors such as for fishing, birdwatching and other activities.  It is imperative that the weir is repaired so as to maintain these facilities for future generations.

The proposed works will be carried out in a manner so as to conserve the heritage value of the structure and to give a minimum operational life span of 75 years.  Additionally the existing fish pass will be replaced with a new modern fish pass so as to comply with the requirements of the Department of Agriculture, Environment and Rural Affairs who has responsibility for the fishery on the Lower Bann.

As part of the design process Waterways Ireland and our  consultants have undertaken surveys and assessments, including extensive land and water based surveys, ecology assessments, noise surveys, assessments of air quality and transportation, flood modelling as well as extensive consultations with landowners, government departments and other local and regional organisations.

Waterways Ireland is aiming to finalise scheme details and submit a planning application in August 2019.  The application will include a full Environmental Impact Assessment.  Works are anticipated to take approximately 18 months with the main in-river works being undertaken in the summer months when water levels are typically lower. 

Waterways Ireland is responsible for the infrastructure that maintains water depths for navigation on the Lower Bann from Lough Neagh to the harbour at Coleraine and along the river owns a number of navigation weirs and locks. Waterways Ireland carries out regular  inspections and surveys of its structures as part of its asset management procedures.
