Water levels in the Monteregie region have reached record highs, and will continue to put as many as 30 municipalities on high alert for flooding over the next 48 hours.

More than 1,500 homes have been flooded around the Richelieu River, Lake Champlain and St-Jean-sur-Richelieu, and about 100 homes have been evacuated.

Public security authorities in the Monteregie area are still keeping a close eye on the Richelieu River, where water levels climbed another three centimetres Saturday, thanks to melting mountain snow and strong southern winds.

Water levels along the river and within Lake Champlain remain high and local residents are also still on alert.

"It's hard, but we're not giving up," said Sainte-Anne-de-Sabrevois resident Vicky Santerre, who hasn't slept since Wednesday as she worked to protect her home with hundreds of sandbags.

Relief should come in the next 48 hours, when the rivers will see water reduction levels of 10 to 15 centimetres, explained Yvan Leroux regional director of public security in the Eastern Townships and Monteregie.

"Right now we're reaching the peak of the situation, since 20 hours ago, and by tonight we should see about four inches less," said Sainte-Anne-de-Sabrevois city councillor Serge Benoit.

A boil water advisory is in effect for anyone who has a natural well, because the water is likely contaminated, said Benoit.

Weather forecasts are on the side of residents, explained Leroux, adding that even though flooding problems are not about to end, sunny condition will help locals.

In Quebec's Beauce area, the flooding situation is improving, thanks to decreases in the levels of the Chaudiere River.

The case is similar in parts of the Eastern Townships near the St-Francois River, where Leroux claims that river levels should continue to drop.
