Erne System

Reducing Water Levels


Waterways Ireland has been advised by Rivers Agency that from 1st October, in keeping with water level management protocols, users of the Erne System can expect reducing water levels throughout the navigation as water levels on Lower Lough Erne are lowered, weather permitting, to a minimum of 149 feet (Above Poolbeg Ordnance Datum), in anticipation of increased precipitation during Autumn & Winter.


If water levels do fall masters should be aware of:



To reduce the risk of grounding masters should navigate on or near the centreline of the channel, avoid short cutting in dog-legged channels and navigating too close to navigation markers. 


Mooring of Vessels

Masters should be aware that water levels may change rapidly and that mooring lines will require adjustment therefore these should be checked regularly.
