Quote: Thanks, OF. I often see signs to Lough Derg when I drive from Dublin to Limerick but I did'nt realise it was comnnected to the Shannon. How far can you get upstream from the Shannon estuary? Is air draft a limiting factor?
Hi Mike,
Yep you can go from the sea through Limerick, through Ardnacrusha Dam up into the lake system which will take you all the way up to Northern Ireland.
The limiting factor is airdraft through Ardnacrusha which is 3.6 metres. KS just made it up a month ago with an inch to spare over the radar arch. OF has no problems as the Broom's radar arch hinges down.
