Thanks to Colin Becker, I have updated this page to show the location of the ESB’s third pumping station between Meelick and Portumna: I had known only where two of them were.
I have also added to the page some rude remarks about the ESB’s policy of not revealing the clearance of their cables above navigable waterways. If, dear reader, you know of a change in the policy, or if you can effect such a change, or if you know the clearances, do please let me know by leaving a Comment.
