Lock 1 / Corraquill Lock – Temporary Closure

Marine Notice No. 35 of 2025 - Shannon Erne Waterway

Waterways Ireland wishes to advise masters of vessels and waterway users that Lock 1 (Corraquill Lock) on the Shannon–Erne Waterway is temporarily closed with immediate effect due to unsafe high water levels, following heavy rainfall in the local catchment area.

Conditions are currently not safe for navigation through the lock. The situation is being monitored closely by Waterways Ireland staff and the lock will be reopened as soon as it is safe to do so.

Waterways Ireland regrets any inconvenience caused and thanks users for their understanding and cooperation.
