Police and military personnel evacuated 800 people from four villages in the low-lying northern Netherlands on Friday amid fears of a dike break following days of drenching rains.
Authorities said that a section of the dike along a major canal could give way and submerge hundreds of hectares (acres) of land under up to 1.5 meters (5 feet) of water.
"The chance is small" the dike will break, said Yvonne van Mastrigt, chairman of the regional policy team that ordered the evacuation. "But in the interests of security of people and livestock I must take this decision."
Dozens of villagers and troops spent hours Thursday night piling sandbags on top of plastic sheets in an attempt to strengthen and waterproof the dike. The local water authority said the emergency repairs had stabilized the situation after water had begun seeping through the dike overnight.
In the early afternoon, authorities opened sluice gates to allow water to pour out to sea, a move that will lower water levels and ease pressure on the strained dikes.
The Defense Ministry also said an F-16 fighter jet equipped with a special camera used to detect roadside bombs in Afghanistan would fly over the region Friday to monitor the state of the dikes.
The evacuations 200 kilometers (125 miles) north of Amsterdam come after a combination of torrential rain and powerful northwesterly winds have soaked the country and prevented water being pumped into the sea.
A quarter of the Netherlands is below sea level and 55 percent of the country is considered susceptible to flooding, but the country has learned to live with the ever-present threat of high water, and devastating floods are rare.
Residents forced to leave their homes were advised to stay with friends or families but a makeshift evacuation center also was opened in nearby sports halls. A local agriculture organization appealed to farmers to come forward if they had extra space to house livestock being trucked out of the threatened area.
Water levels in rivers and canals across the Netherlands has been rising for days and authorities are on high alert for possible flooding and breaches in the thousands of kilometers (miles) of dikes that protect the country from inundation.
In the northern city of Groningen, staff at the Groninger Museum moved two exhibitions late Thursday from ground floor halls because of the rising level of a moat that surrounds the building. The museum was closed Friday.
