Waterways Ireland advises masters of vessels and users of the Shannon Navigation that the Great River Swim will take place between Tarmonbarry and Ballyleague next Saturday 20 May.

As many as 800 swimmers as expected to participate in the swim event, the cross-border body for Ireland’s inland waterways adds.

The Shannon Navigation between Tarmonbarry Lock and Ballyleague bridge will be closed from 9am to 2pm on the day.

Tarmonbarry Lock and Clondara canal lock will also be closed for the same time period, while vessels will be prohibited from proceeding upstream from Ballyleague Bridge during this same time.

A series of large bright green and red buoys — branded with Gaelforce — will be positioned along the swim route on the evening of Friday 19 May and will removed after the swim on Saturday.
