Heavy rains in France lifted the Seine on Friday to its highest levels since 1982, threatening Paris's cultural institutions and soaking the French countryside east of the capital.

The Seine has continued to swell since the river burst its banks on Wednesday, raising alarms throughout the city. As of 10 p.m. on Friday, its waters had reached 20 feet. The river was expected to crest on Saturday morning at up to 21.3 feet, and to remain at high levels throughout the weekend, the French Environment Ministry said in a statement.

The situation is still evolving hour by hour," a deputy mayor of Paris, Colombe Brossel, said at a news conference at City Hall, adding that the authorities estimated that it would take at least a week or more for the water to recede to normal levels, which are typically three to six feet above the standard reference point for measuring the height of the river.

Near the Cathedral of Notre-Dame, pieces of tree trunks floated along the swollen river. The waters had risen to the waistline of the Zouave, a notable statue next to the Pont de l'Alma that has traditionally been used as a gauge of the Seine's levels. The city's government urged residents to move valuables out of their basements. An art collection had to be removed from the city hall in Ivry-sur-Seine, a southeastern suburb of Paris.

"Around the Eiffel Tower, the banks are flooded," said Julien Rogard, 23, an engineer who takes the No. 6 Métro line, which crosses over the Seine on the Pont de Bir-Hakeim. "Where we usually can walk, we can't anymore."

The Seine has not overflowed this much since December 1982, when it rose to about 20 feet, but the river's level is still short of the 26.2 feet reached in the catastrophic flood of January 1910.

Parisians and tourists thronged to take photos of the swollen river, prompting a warning from Ms. Brossel, who said: "There are still people going on the riverbanks to take pictures. It is not safe. We are asking you to respect the ban on going there."

The government has made emergency plans to shift operations from the Élysée Palace, the seat of the French presidency, to the Château de Vincennes, a former royal fortress just east of the capital, if the waters go above 21 feet.

"We're not yet at this stage," an official at the general secretariat for national defense and security told the magazine Le Point. "For now, we're making sure that all plans are ready and that the different measures may be set in motion to ensure the continuation of governmental work."

Officials expressed fears that telecommunications and computer equipment on the lower floors of the Foreign Ministry building on the Left Bank could be inundated. They said the ministry's archives had been moved to the suburbs in 2010 for safekeeping.

Across France, 20,000 households were without power on Friday, mostly in the Seine-et-Marne area, east of Paris, and in Essonne, south of Paris, a result of the swelling of the Marne and Loing tributaries of the Seine.

Workers in Paris erected a special barrier on Friday morning to protect an underground electrical transformer station near the Pont de l'Alma. The substation provides power to about 80,000 customers in the Seventh and Eighth Arrondissements.

The evacuation of artworks from the Louvre, which was closed to visitors, has attracted particular attention. Starting on Thursday, officials at the museum activated an emergency flood-protection plan established in 2002, prioritizing the most fragile artworks, such as tapestries.

An estimated 150,000 artworks in storage rooms and an additional 7,000 pieces in galleries were vulnerable to flooding, and a large portion of those were moved to higher floors as a precaution, officials said.

Officials emphasized that no waters had entered the museum.

Other cultural institutions that were closed on Friday included the Musée d'Orsay, which is in a former train station on the Left Bank; the Musée du Quai Branly, which is devoted to non-Western art; and the main Bibliothèque Nationale building, named after former President François Mitterrand.

The Musée Girodet in Montargis, a town about 77 miles south of Paris, suffered heavy damage on Thursday. The museum is devoted mainly to the work of Anne-Louis Girodet, a Romantic painter who died in 1824.

Heavy rains also caused deadly flooding in Germany, particularly in the southwestern state of Baden-Württemberg and in the southern state of Bavaria.
