MARINE NOTICE No 58 of 2021
Grand Canal Main Line, Barrow Line and Royal Canal 
Low water levels
Cautionary advice

Waterways Ireland wishes to advise masters and owners of vessels that low
water levels continue to be experienced on the Grand Canal Main Line, Barrow
Line and Royal Canal at this time. Some levels are currently 450mm down on
normal levels. 
The recent prolonged dry spell of weather together with the pattern of rain
fall has adversely affected the sources which supply water to the navigation
systems. The unusually hot weather has not only reduced the sources of water
but has also caused loss through evaporation.
Masters of vessels are advised to proceed with additional caution and to
contact the water patroller for latest advice and assistance.
Waterways Ireland apologies for any inconvenience caused.

P Harkin
Inspector of Navigation
