Waterways Ireland wishes to advise masters of vessels of a planned temporary reduction in water levels at Shannon Harbour. The purpose of which is to facilitate excavation works for the construction of the new jetty, while minimising environmental impact along the bank.
Water levels will be lowered by approximately 200mm for 6–8 weeks. The reduction will be implemented as soon as possible, commencing 13 April 2026, subject to operational requirements.
Concurrently, a construction pontoon will be in place and operating within the navigation area during the works. While vessel passage past the works will remain possible, it will be restricted. Masters of vessels are requested to proceed with caution and to comply with instructions provided by site staff.
Vessel owners are advised to check and adjust mooring lines from 13 April to accommodate the reduced water levels. Waterways Ireland staff will also monitor and adjust moorings where necessary.
Waterways Ireland regrets any inconvenience caused and thanks all users for their cooperation.
