How many locks are on the river Barrow?

This is a question I get asked on a regular basis from those on our boat trips. I usually tell people that there are 23 locks of the Barrow Navigation system between Athy and St Mullins. The reason I say “usually” is because you could argue that there is 24. This is because the lock at Ballykeenan, just north of Graiguenamanagh is a double lock. It is two locks, one directly after the other. When you exit one chamber of the lock you enter the chamber of the second lock. Some have argued that it is two locks but Waterways Ireland refer to it as a double lock but count it as one in their Guide to the Barrow. Given that it has three sets of gates instead of four, with the centre gates acting as both Breast and Tail gates, it’s probably wise to count it as one lock, while noting it has two lock chambers. Therefore the number of locks on the river Barrow is 23.
