The flow of water through Parteen Weir is likely to increase in the coming days, given the high levels of rainfall forecast in the Shannon catchment, as a result of Storm Frank, the ESB has confirmed. The flow is set to increase to 440 cubic metres per second later today (Tuesday).
The levels in Lough Derg are likely to increase to 2009 levels in the coming days and, as a result, the flow through Parteen Weir may increase up to 2009 levels (up to 500 cubic metres).
This level of water flow will have increased associated flooding to land and property in the vicinity of the Shannon downstream of Parteen Weir including the areas of Springfield, Montpelier, Castleconnell, Mountshannon (Annacotty) and the University of Limerick. Note that other areas between Parteen Weir and Limerick may also be vulnerable to flooding due to local issues.
The ESB is continuing to monitor the situation and is liaising with the relevant local authorities.
Following Storm Desmond, between Sunday, December 13 and Wednesday, December 16 flow of water through Parteen Weir down the old River Shannon was at 440 cumecs.
