Pollaphuca Reservoir, also known as Blessington Lake, is the largest reservoir in Ireland, covering approximately 5,000 acres (2,000 hectares) and formed on the River Liffey. Situated roughly 19 miles from Dublin and approximately 600 metres above sea level, the reservoir boasts an impressive 56 kilometres (about 50 miles) of shoreline punctuated by numerous bays that provide excellent angling opportunities. The Electricity Supply Board (ESB) controls and manages this fishery, which operates as a mixed fishery supporting both game and coarse angling. The reservoir's many sheltered bays, varied shoreline structure, and productive open water make it one of the most significant and accessible angling destinations in the Leinster region.
