I am grateful to Waterways Ireland for letting me have the Shannon traffic figures for the first five months of 2015. All the usual caveats apply:
- the underlying figures do not record total waterways usage (even for the Shannon) as, for instance, sailing, fishing or waterskiing on lakes or river stretches, which did not involve a passage through a lock or Portumna Bridge, would not be recorded
- the passage records would not show, for instance, a change in the balance of types of activities from those in larger cruising boats to those in smaller (sailing, fishing, waterskiing) boats
- figures like these will not necessarily be representative of those for the year as a whole. The winter months, January to March, see little traffic in any year; for April, May and June, the weather can have a large influence on the amount of activity especially, I suspect, in private boats.
On the other hand, the figures do include the Shannon’s most significant tourism activity, the cruiser hire business. And they are our only consistent long-term indicator of usage of the inland waterways.
The big news is that there is an increase in the amount of hire-boat traffic and a decrease in the amount of private traffic. [Personal observation suggests very little activity on Lough Derg, apart from the sailing bods.]

Nonetheless, hire-boat traffic is still close to 40% of what it was in 2003, with no sign of a major recovery
In January, 18 boat passages were recorded, 9 of them at Portumna Bridge. There were 20 passages in February and 362 in March. Is there any point in keeping the Shannon open throughout the winter?
In the first five months, 11 boats used Sarsfield Lock, the sea-lock in Limerick. There were 88 passages through Pollboy Lock on the River Suck. On the Lough Allen Canal, 96 boats went through Battlebridge Lock, 95 through Drumleague and only 38 through Drumshanbo. These branches can’t be paying their way.
