A GROUP OF rescuers were involved in saving a herd of horses stranded on an island on the River Shannon this morning. According to one of the team, the animals wouldn’t have survived another night, without the intervention. The horses found themselves stuck on Ballymacegan Island, on the border between Galway and Tipperary today, after rapidly rising water levels on the River Shannon. Unable to save them himself, their owner contacted the Athlone Sub Aqua Club.
