Some beautiful UAV footage of Barlogue Creek and Lough Hyne that I came across online. I did my PADI Open Water diver tests in that channel in 2007. It wasn't that clear on the day, as we had had one of the wettest summers on record and all the run off had made the water very turbid. Still - some of my favourite spots in the country are around here. The clarity of the water provides some tempting sites to look at for optical bathymetry tests.
