Forecasters are predicting less rain on Tuesday but the high water level of many of Spain's rivers is continuing to cause serious problems.
The current situation is most difficult along the River Duero, especially where it passes through the provinces of Zamora and Valladolid.
In Castilla-Leon, water levels should be more or less stable in the next few days, according to José Valín of the Hydrological Confederation of the Duero.
"This depends on rainfall over the course of this week," Valín was cited as saying by national broadcaster RTVE.
A travel advisory issued on Monday warned of flooding affecting nearly all of Spain's river basins.
Also on Monday, a motorist and a truck driver died when a bridge collapsed in central Spain following torrential rains, regional officials said.
The collapse in Fuencaliente, northeast of Cordoba in Castile-La Mancha province, caused a car and a truck to plunge into the Yeguas River, they said.
The driver of the car was aged 23, the officials said, without stating the age of the truck driver.
On Saturday, a cyclist died near the Colemenar in Madrid's sierra.
Authorities say that he probably drowned when he attempted to cross a swollen stream on his bicycle.
In the Sierra de Alcaraz in Albacete, meanwhile, 25 people were stranded at a campground because of a rising Mundo River which blocked the only access to the facility.
