If the natural reservoir dam wall is breached the village would flood within an hour. The evacuation is being described by North Wales police as a "precautionary measure" but fears are running high in the region following the flooding in Aberystwyth on Saturday where villages were flooded by 5ft (1.5m) of water. The Environment Agency Wales said the flooding had been an "unprecedented event," reports the BBC
The situation in Pennal on Sunday is being described as "manic" with local publican, Gwyn Davies fearing the pub he leaves behind this evening could be gone when he returns. Authorities at the village include council workers, fire services, water authorities, environmental officers and police.
at the dam said a crack had developed in the dam wall, this allowed small amounts of water to escape. The reservoir is a natural one and if the wall was totally breached it would cause the river below to overflow and burst its banks. The river runs through Pennal.
Authorities are optimistic that providing the situation shows no further deterioration over the coming hours, then villagers should be allowed to return to their homes.
The flooding fears come just a day after 48 people were rescued
from homes and caravans in West Wales, near Aberystwyth.
