IMMEDIATE and longer-term plans to manage flood risk in Porthmadog and Tremadog are being put in place, says Natural Resources Wales.

Concerns have been raised about flooding in the area following devastating floods in Tremadog at the beginning of the year and the floods during Festival No 6, which left hundreds of cars stranded in fields near Porthmadog Football Club.

Gwynedd Council has carried out investigations into the last three flooding incidents in Tremadog since 2011 and found they were caused by severe storms which carried vast amounts of debris into the intake structures at Twll Mwn.

The debris reduced the capacity of the culverts, resulting in the water overspilling and finding its way into Tremadog.

Natural Resources Wales say to avoid blockages at Twll Mwn, Gwynedd Council inspects the culverts on a weekly basis and are cleared as and when required.

In its newsletter, it said: “In terms of longer planning, Gwynedd Council’s Water and Environment Unit is looking at catchments in the county – including Tremadog - that need improvement in terms of managing flood risk. Once projects are drawn up, a bid for funding will be made to the Welsh Government.

“Options might include having more screens located upstream of the Twll Mwn culverts to catch the initial flush of debris in a storm.

“As well as securing funding from Welsh Government, the co-operation of landowners would also be required before such a scheme could proceed.”

NRW also said it will be repairing the tidal door in Porthmadog this month.

In November, to prepare for the winter, and to remove any potential restriction in the sewer network, Welsh Water will also flush out the sewer pipes in the area.
