Blessington - Poulaphouca Reservoir

Poulaphouca Reservoir

Also known locally as the Blessington Lake, the reservoir was created when the waterfall at Poulaphouca on the River Liffey (which flows from the Wicklow Mountains to Dublin) was dammed by the ESB for a hydroelectric plant which is still in use today. The valley was flooded and the resulting lakes extend over approximately 5,000 acres (20 km²). A small village was submerged by the damming of the waterfall, and the remains of roads can still be seen leading down into the lake.

In addition to electricity, the lakes also provide water for the locality and the Dublin region as well as provide a leisure resource. There is now a lakeside luxury hotel complex in the Blessington area, with its own helipad, and lakeside facilities which has helped to develop tourism in the area. The lake is also extensively used by boatmen and fishermen, and is a training location for the Irish Air Corps HQ divisions from Baldonnel, 15 km north of Blessington, and also Local Civil Defence Water rescue teams.
