The Geological Survey of Ireland is conducting an airborne geophysical survey – the Tellus North Midlands project. See www.tellus.ie for up-to-date flight lines on an interactive map with aerial imagery and map details, or freephone 1800 303 516. The aircraft will fly at an altitude of 90 metres in rural areas with an instrument towed beneath the aircraft at an altitude of approximately 45 metres. The aircraft are C208B Cessna Grand Caravan planes with registrations ZS-FSA and ZS-SSA.
The extended period of dry weather has meant that water levels in the navigations are presently lower than normal for this time of year. Make sure you stay in the centre of the navigation channel, do not cut corners, don’t navigate too close to markers.
Drumshanbo Lock is closed for essential lock gate repair until Friday 24th October 2014.
Recent surveys have detected aquatic weed in significant quantities in Upper Lough Erne. There is a risk of vessels being disabled due to fouling of propellers and by weed being drawn into the engine intake, causing it to overheat and stop.
- stay within the marked navigation channels
- be aware that weed may be encountered in any location where there is a water depth of around 1.8 metres or less
- navigate with caution
- keep a sharp look-out and
- proceed at slow speed where the hazard of weed exists.
Take account of any temporary aids to navigation placed by Waterways Ireland. Hazard warning signs highlighting the presence of weed or temporary navigation markers (red/white square) will indicate channels from which weed has been cleared; always pass on the white side. In the event that a vessel fouls the propeller due to weed, stop the vessel and go astern (reverse) on the engine for a few seconds to see if the propeller clears itself. If, after two or three attempts, this proves unsuccessful, ring our office. Allow extra time to make a passage under these environmental conditions
The red porthand buoy marking the entrance to the marina at Garrykennedy has been reported as being out of position. A temporary red porthand buoy has been placed on station. Masters should approach the marina entrance with due caution.
