Tanygrisiau Reservoir

Today was probably going to be the best weather during my stay if the forecasts are accurate (bearing in mind the uncertainty of what happens with former Hurricane Erin as it arrives over here), so I had a trip to Cwmorthin and then followed that up with a visit to the nearby Tanygrisiau Reservoir, which is the lower of the 2 reservoirs for the Ffestiniog Pumped Storage Hydroelectricity Station.
