Requirements of DfI Rivers
DfI Rivers is required to regulate and control water levels in Lough Neagh within a specified range, that is 12.450 metres to 12.600 metres Ordnance Datum, as defined in the Lough Neagh Levels Scheme (1955) (as amended).
Water levels in the lough are controlled by means of flood gates at Toome at the head of the Lower Bann river. Further control within the Lower Bann River is managed by two sets of flood gates. These are located at Portna (near Kilrea), and The Cutts at Coleraine.
The channel in the Lower Bann River, downstream of Lough Neagh, tends to impede the rate of outflow from the lough during periods of heavy rainfall. At such times the floodgates at Toome are fully opened, where possible, in advance of an anticipated rise in water level.
