Emergency officials are watching water levels along Nova Scotia's south shore but no further evacuations are planned in the area that has been hit by heavy rain and flooding since the weekend.

More than 220 millimetres of rain has hit the region, washing out a dozen roads and forcing the closure of several bridges.

About 100 people in the Fancy Lake area, about 90 km southwest of Halifax, have been kept from their homes since a local state of emergency was declared Wednesday evening.

"There certainly is significant flooding in areas. But we've evacuated no more people since that rain," said Brian Kaizer, with the province's Emergency Measures Organization.

Bridgewater Mayor Carroll Publicover told CBC News that the water levels are still high and rising.

But he said the "forecast gives us some room for optimism."

Concern about wells

With water levels so high, the Department of Environment and Labour is advising flooded residents not to drink their well water until it's been tested.

Flood water can carry sediment into wells that aren't tightly capped. Wells that are older than 10 years, or less than 15 metres deep, are more likely to be contaminated.

In the district of Lunenburg, about 100 people had to be evacuated from over 60 homes, which prompted municipal officials to declare a local state of emergency Wednesday.

Doug Quinn, the chief administrative officer for the district of Lunenburg, says more than 60 millimetres of rain fell Thursday.

Nova Scotia Premier John Hamm visited the region Thursday and said his government is "going to assess [the] damage and we will act appropriately."

Hamm says if the damage tops $1 million, he will ask Ottawa for help.
