Ardnacrusha Lock & Limerick
Ardnacrusha is a double lock managed by the ESB as part of the hydroelectric scheme on the Shannon. Water levels and currents between Ardnacrusha and Limerick can vary widely.
Users are strongly advised not to travel on this stretch of waterway when more than one power station turbine is running, due to the increased velocity of water. Increased water flows are also to be expected following spells of heavy rainfall. Always consult the advice notes before travelling which are available on our website under marine notices.
A separate guide “City Cruising” is available from Waterways Ireland and Tourist Information Centres locally.
For times of opening and all information regarding Ardnacrusha please contact: Tel no +353 (0)61 344 515.
Before travelling to Ardnacrusha please contact the lock-keeper to book your passage: Tel no +353 (0)87 997 0131 or Tel no +353 (0)61 344 515. The lock-keeper will advise the staff at Parteen Weir of your estimated time of arrival.
