As I understand it, the level of Lough Erne, and the occasional need to use its only lock, at Portora, are both determined by the operations of the Lough Erne hydroelectric scheme, although most of the lake, and the lock, are in Northern Ireland, while the hydroelectric stations, at Cliff and Cathaleen’s Fall, are both in the republic. The Erne scheme is less well known, and has been less often written about, than the Shannon scheme at Ardnacrusha, so it is good to note that two Ballyshannon men, Dessie Doyle and Brian Drummond, have written a book about the Erne scheme.
Unfortunately it is not clear from Messrs Lilliput Press’s website whether the book has already been published or is to appear some time in 2014. No publication date is given, but on the other hand it is not in the list of forthcoming books, but that list does not extend beyond November 2013. I would be glad to be able to carry reliable information, but I regret that I am unable to do so.
