From Wikipedia, the free encyclopedia.
The River Shannon, which divides Ireland into east and west, has been an important waterway since antiquity. First mapped by Ptolemy, the 200 mile long river empties into the Atlantic Ocean in a western direction at Limerick, turning north in the city.
Tributaries include the River Suck and the River Brosna.
There is a hydroelectric generation plant at Ardnacrusha.
