The Home of Emergency Services, a state organisation, said in a statement that 46 people had been injured, and six of them were killed in the city of Erzurum.
Several buildings collapsed.
The move comes as Turkish flood experts have warned that they will have to cope with rising water levels caused by climate change.
In nearby Zonguldak, the Sutlu river has flooded a local hospital.
“Eighty percent of the hospital flooded,” said Gokce Akpirlu, an employee of the Hölü hospital.
