Canals
Before lorries and trains, canals were the most common way of transporting goods.
However unlike a river which flows downhill, a canal is flat and therefore stretches of water are at different levels.
Some famous Irish canals are the Royal Canal and the Grand Canal. They both join the River Shannon to Dublin.
There are many more canals all over Ireland. One of these these is called The Cong Canal (The Dry Canal). It was a canal between Loch Mask and Loch Corrib but it was never used. Why?
The Panama Canal
